It's not clear to me what you mean.  Was there an *error* message?  If so,
what does it say?

If you simply mean "I expected a graphical interface, and instead I got
a text console login prompt", that's because you used the -standard image
which has a minimalist set of packages, equivalent to what you would get
if you installed Debian normally, and un-selected the desktop environment

If you want a graphical interface, you'll need a different image.



I agree with Greg - I use Ventoy/debian-live-12.2.0-amd64-xfce.iso and 
it works just fine in the xfce graphical interface. Use the desktop you 
prefer as part of the debian live iso for a graphical install.

Hi Sophie,

We are asking you questions because we can't see you, we can't see 
what you type, we need clear information.

It's like playing chess by post: every time we ask for details
on what you have - what has happened, how the pieces are laid
out - we get an "I have a chess problem" message.

In your reply, please try and answer each of the questions
written below *under* the question so it is clear. If you only have
a phone to reply, that's OK, but please reply to one question
at a time in that case.

Please try and keep to the subject of the message. I have changed
that to "Problem booting the machine" I expect your reply to be
something like AW: Problem booting the machine

First - and most important question - is this your only computer?

If so, I would not want to break it further but in order to fix it,
we will need more information.

Second question - is this the computer that you mail us from to this list
or are you using some other device to mail us?

Your reply above has given more information: this happened after
you upgraded from Debian 10 to Debian 11. 

Third question - Even if it's now more than two years ago: can you
remember whether the upgrade completed successfully?

Fourth question -Is it that when the computer starts - and you get a
(blue or green??) first screen with white writing, it lists 
several kernels to choose from?
 
Fifth question - If you have only one kernel listed, then under that may be
a "rescue" option - is that what you use to boot the machine every
day?

If so, then *what do you type* to get into the system: what commands?

Sixth question - One line may list the Debian 11 kernel version -
with 5.10 - or may list the Debian 10 kernel version - with 4.19
Which do you select  / which one works?

Thank you in advance for your replies

FWIW check the BIOS L[123] cache settings and consider changing them to
more conservative "slower" values if possible. And you have different RAM
models and configurations, could there be one DIMM in the mix that is
running overclocked?

  as i may have said before.  whatever you have going on
with file saving and file system access may be getting
stomped all over by whatever settings you have in the KDE
desktop or the particular application.  so one thing i
would do for sure is make sure that the KDE desktop file
extension associations that may be turned on to do anything
automatically are turned off (until you resolve where the
issue actually resides).

  once you have the KDE desktop stuff turned off then you
can at least know it isn't that which is mucking you up.

  from there is it some other thing?  well, if it now 
works then you've solved it, and if it hasn't been solved
then you've at least eliminated one variable.

  from there if it still does not work then you are up 
against any automatic automounter crap (which i find a
PITA so i remove it or find ways to turn it off which
then gets through another layer of possible variables).

  after that you should be down to the applcation and
what settings it has for dealing with file and accesses
and again i turn off all automatic stuff i can there to
make sure exactly what i'm trying to do can get done with
minimal interference.

  since you have network stuff going on which i hardly
ever do and i also don't do bluethooth, samba, ssh, rpc 
(or plenty of other things) well then you're going to
have to wade through those things and see what each may 
let you do to narrow down where the issue is at.

  when you have a complicated system it may be well 
worth it to set up a blank slate new machine and put in
each layer and test it before adding the next to see
which step is going kerblooey.  if i'm running a 
production system this is a natural and common 
procedure for any upgrade and debugging.  gotta have a
way to do tests that doesn't shut down production.

been made to understand that resolv.conf is now not the place to put

There was once a stanza at the end of dhcpd.conf where one could setup 
his network by filling in the blanks and removing the # comments. If all 
else failed, that worked, But that was too easy so it was removed. And 
I'm back to hunting for the reason I can ping yahoo.com but not other

does not seem to be any consistency.


Take care & stay well Brian.

If I understand correctly, Gene identifies himself as "a hosts file
user" and one of his major delusions is that there is some
conspiracy within the Debian-like world to make the life of people
who make use of /etc/hosts very hard. One of the ways, in this
delusion, that it is made hard is by "forcing everyone to use a DHCP
server", which also leads to Gene's resolv.conf being modified,
which Gene does not like and uses the immutable file approach to
prevent.

I think since I have criticised the immutable resolv.conf "solution",
Gene has decided I must be part of this wide-ranging conspiracy and
so I must be offended that he *also* uses hosts files. That is, he's
saying I am offended by "a hosts file user", i.e. him and by
extension what he does, not offended by "a hosts file". It did take
me some effort to parse.

That is my best guess at how this particular one of Gene's bizarre
rants even tangentially connects with reality as I know it, anyway.

Cheers,
Andy

Sorry you are so offended by a hosts file user Andy, but when the guys 
decide to do networking differently, usually in the badly mistaken idea 
that everybody runs a dhcpd server even for their isolated local 
network, and don't check that their brainless changes don't screw up a 
host file based local network, or worse, don't care if it does, then you 
should expect that we WILL do what WE KNOW JUST WORKS.  Blaming me in 
that case is just plain poor form.  If there indeed IS a better way to 
deal with this in a hosts file system, then teach us /how/ WITHOUT 
ASSUMING we'll just run a dhcpd server with all the configuration sand 
maintenance bs that entails. Tain't gonna happen.


We hide our local stuff behind something like dd-wrt and its ilk for a 
reason.  As a guard dog, its an 800 lb pit bull with a very bad attitude.

Yes my system is exactly using NM for networking. so resolv.conf is just a
symlink. I delete that symlink and create a real file, put content into it
(no chattr needed), and reboot the OS everything works fine now.

I must admit that I was one of those proposing chattr +i in this
context (it feels like half to one decade ago). To my defense, I
said then (and repeat now) that I don't recommend it as a permanent
fix, rather as a debugging tool. The next step would be to go to
the logs and see which software is complaining. Then you know which
man pages to hit :-)

Leaving "chattr +i" behind in /etc at random spots will come back
to shoot you painfully in the foot (e.g. at the next system upgrade,
when you'll have forgotten about it).

If the sysadmin is me, I'll just leave it for as long as the single
debugging session lasts.

Then you'll [1] come here, whining ;-)

So you honestly do not see a problem with how this has played out,
despite your tone in the preceding paragraph where you seem
exasperated that Jon has not taken the time to understand the
problem or read any of the documentation or basically do anything
that involves effort on their part?

I'm surprised I need to clarify this, but I'm not disappointed
because Jon chose to make a file immutable, I'm disappointed because
Jon leapt at the option that involved pasting some commands in
without understanding them or what is actually going on with their
machine. And not purely because I think Jon ought to understand
these things as some pure ideal state of being, but objectively
because when Jon hits any sort of networking problem in future, Jon
will STILL have no idea how their network is actually set up. Which
is astonishing for someone wanting to run a server. And this
attitude will be applied to other parts of the system. And this list
will see Jon or someone like them again very soon and be asked to
unpick this behaviour.

Here I think chattr +i is a useful tool that should be used to reach
a state of understanding if necessary, not an actual fix. I agree
that it belongs at the bottom of documentation and couched with
caveats, not handed out as a "just do this". That's very sad to see.
And even sadder to see promoted as the "solution".

Cheers,
Andy

And so another one fails to spend the time to work out how their
operating system works for trivial minutiae like "how my network
gets set up", leaving a nice rake in the grass for some point in the
future when they are trying to debug something else. 

And we wonder why this list ends up dealing with the aftermath of
the Gene school of "don't understand it? Hit it with chattr +i / rm
/ apt-get purge!" so often.

The first thing you could do is check whether a DHCP client daemon
is running.  That's usually a sign.

Failing that, find out what your primary network interface's name is,
and then find out how that network interface is brought up.  In a server
configuration, it's *usually* brought up by a stanza in the
/etc/network/interfaces file.  If that stanza consists of a line
ending with "dhcp", then voila.

If the primary network interface is not configured in /e/n/i then the
second most likely configuration is NetworkManager.  Usually if NM
is in the picture, /etc/resolv.conf will be a symlink, and you will
see evidence of NM both in the symlink's target, and in the contents
of the file.  Thus,

ls -ld /etc/resolv.conf
cat /etc/resolv.conf

Both of these should give you hints, if NM is involved.

These same steps are also on the wiki page that's been discussed many
times in this thread.  You might want to read what the wiki has to
say about it, especially about /etc filling up with temporary files.

They're also the same steps that someone else in this thread has
criticized.  Again.  As you can see, some people simply *despise* this,
despite how simple and effective it is.

They can't say WHY it's wrong, of course.  Maybe because it's too simple
and effective.  I dunno.


How about the fact that it just solves the symptom but not the real problem?

/etc/resolv.conf does not change by itself, some tool must be making the 
(possibly undesired) changes, so in most cases, I'd say it's better to 
configure that tool to stop changing resolv.conf, or to add the 
nameservers you want instead of whatever the tool auto discovers. Or 
perhaps you don't even need that tool (in a server with static IP, for 
example).


I'm not saying that chattr +i should never be used, but it should be the 
last resort, and the user should know what they're doing and possible 
consequences.

The file /etc.resolv.conf is just a soft link.

You need to:

1: Delete /etc/resolv.conf - rm /etc/resolv.conf
2: Create a new /etc/resolv.conf file: touch /etc/resolv.conf
3: Configure you nameservers
4: Make the file immutable: chattr +i /etc/resolv.conf

I am not sure about the details. But with DHCP a bunch of network
configuration items can be send from the server to the client. The
nameserver configuration is one of the items.

It's a VPS provided by a local ISP. The VPS has a static IPv4.
Do you know how to know if /etc/resolv.conf is modified by dhcp?

In case you get the configuration overwritten by DHCP you can avoid that
by the following lines in /etc/dhcp/dhclient.conf.

interface "bond0" {
supersede domain-name-servers 127.0.0.1;
}

Just replace the interface name with yours.

Not all Debian systems are in a "data center".  Sometimes they're on a
home network, or a workplace network.  In both of those environments,
the DHCP server may be questionable -- either because it's being provided
by a cheap router (home), or because it's being managed by a different
department (workplace).

Some workplaces require the use of DHCP to configure network interfaces,
even when the DHCP server behaves in a way you do not wish.  For example,
it may offer DNS nameservers that are not the ones you want to use.  So,
many of us are running Debian systems where the IP address has to come
from DHCP, for political reasons, but the DNS servers that would come
from DHCP are *undesired*.

Therefore, we want to edit /etc/resolv.conf ourselves, and not let the
DHCP client daemon, or any other program, change it.

Therefore, this wiki page.

Do you have a specific wording change you'd like to see?

Is there any part of the page that is actually *incorrect*?

Are there any alternative solutions that are *missing*?

I'm referring to these exact words:
"It also works well for many desktop and server systems, so long as the
network infrastructure is perfect."

Its a red herring because the DNS infrastructure in a data center is static
at the IP address and host name level. And I feel certain that any network
infrastructure constructed by humans is imperfect to some degree.
There's their escape hatch.

Those words do not appear on that page.  I don't know which sentence(s)
you're actually referring to.  The closest thing I see there is "so
long as the network infrastructure is perfect", which refers to the DHCP
server, not the Debian system.

A lot of us run Debian systems on networks where we DO NOT CONTROL the
DHCP server, and have to work around it.  That's what the introduction
of the page is talking about.

In any case, appeasing EVERY reader is impossible.  I have to use vague
wording to try to make sure nobody is offended that their personal
preference configuration is not snubbed.  No matter how utterly batshit
insane such a configuration may be from my point of view.

I'm also forced to relegate the chattr solution to the end of the page,
and couch it in caveats, because some people think that it's wrong.
They can't say WHY it's wrong, of course.  Maybe because it's too simple
and effective.  I dunno.

People are horrible sometimes.

With all that in mind, and considering that this is a WIKI and you may
edit it your damned SELF if you disagree with the content, what is your

Contrary to what that page states, auto changes to resolv.conf are never
appropriate in the server environment. The statement there that it works
fine in a "properly configured server" is the boilerplate escape hatch for
that inconvenient fact :-)

You might want to read this;

https://lists.ubuntu.com/archives/ubuntu-users/2023-June/310491.html

and, of course, after that procedure, in the system UEFI/BIOS, change 
the boot order to


USB drive
Optical (eg, DVD) drive (if the computer has one)
HDD

so that the computer should attempt to boot from the respective 
drives, in that order.




It occurred to me, after posting the above message, that I should have 
worded that last part, slightly differently, for clarification; the

"and, of course, after that procedure, in the system UEFI/BIOS, change
  the boot order to"

should have been

"and, of course, in that procedure, while still in the system UEFI/BIOS, 
between steps 2 and 3, change the boot order to".

In this, since I last posted, I remembered that, on one of my computers,

If the original poster has not yet been able to boot into a Linux iso

You can download a bootable CD-Rom from this site:

Look for the Bootmgr. It is a live-cd., which is booting, then you can chose

It helps, whenever your BIOS does not have the capability (i.e. it is too old), 
to boot from USB.

Hope this helps.

(after reading the other comments)

I recently had a similar issue with a HP 840G3 laptop

after editing the BIOS to disable secure boot and setting the boot order 
no joy.


I discovered that holding down F9 and then pressing the power button it 
goes directly into BIOS boot menu.

THEN selecting the USB drive from the list it works.


maybe your laptop has some such direct boot path option
best of luck

I don't have experience with your specific problem and after reading the
rest of the thread, I'm not sure what might be the problem or how to fix
it, but faced with this, I think I'd try to open the machine up and
remove the "disk" to which it boots (i.e. the one with Window-11 on it).

Not sure it would fix the problem, but if not I'd hope it might give
further hints.

It occurred to me, after posting the above message, that I should have

Check what devices are enabled in boot settings in system setup (BIOS or

When you switching off a computer with windows, perhaps actually it 
performs suspend do disk (hibernate), not shutdown. Alternative boot 
options may be disabled when system is resumed from hibernation. Ensure 
that you namely *shutdown* windows. The following page suggests that it 
may be configured in "System and Security". Perhaps some modifier (Alt

I may have missed it: have you tried going into Windows 10 and into 
setup, looking for 'boot' in the search bar and select 'change 
advanced startup options'? then you go to "Advanced startup" and 
hit "Restart now"?


When the machine reboots go into the BIOS/UEFI system and select your 
usb.


Sorry if this has been proposed already and I missed it. Also sorry if 
it doesn't work. I have to do it if I want to boot from usb on my Acer

Sorry, i have no experience with this concrete issue. Last time, i
experienced USB boot issues, it did help to just use another USB-port
instead. ;-)

But honestly, i see many hints and advices are coming, but still the
cause of the problem has not yet been identified, which would be my
first attempt in any case.

Since you confirm, that booting from the stick is possible on another
machine, it cannot be, that the stick itself doesnt work. But does that
other machine also have the same processor architecture (celeron ...)?

IIRC it is possible to boot a 32-bit OS on a 64 bit machine (not
recommended, but possible), whereas the other way round would just fail.

Sure, in here Windooze is regarded as a nuisance, but even windows can
inspect its boot config and determine, how the machine is coming up, if
the disk has GPT or MBR (probably the first), and you might be able to
find out, if your setup allows ANY booting from USB (like non flash
storage).

Even without aspiring for completeness, i was suggesting different areas
being possibly of concern, like
- hardware (usb, processor)
- bios (setup)
- version mismatch (partition tables, OS-architecture)
- there may be more (like secret holes leading to hidden switches)

Once the cause will be identified, it is going to be much easier (or
just plain impossible) to remedy the problem. And please report back,
what you found.

Other than with legacy BIOS, EFI looks for different boot programs in the
EFI System Partition's FAT filesystem:
i386:  \EFI\BOOT\BOOTIA32.EFI
amd64: \EFI\BOOT\BOOTX64.EFI

debian-11.7.0-i386-netinst.iso only offers BOOTIA32.EFI :
  mount debian-11.7.0-i386-netinst.iso /mnt/iso
  mount /mnt/iso/boot/grub/efi.img /mnt/fat
  find /mnt/fat
So a normal amd64 EFI will not consider booting it.

The MBR code for legacy BIOS should be usable for 64-bit and 32-bit
alike. But Rodolfo Medina's machine seems not to like the USB stick in
CSM mode.


Have a nice day :)

Perhaps we have to distinguish between "CPU can run 32-bits too"
and "a particular UEFI can boot into a 32-bit OS".

I should have included, in my previous posts about this, that the 
imperative first step, before either using a newly purchased computer, 
or, trying to add an extra booting operating system to any computer, new 
or otherwise, is to ensure that you have the latest available UEFI/BIOS 
installed on the computer.


The computer manufacturer's web site should have the applicable 
procedures involved,  for both checking the installed and latest 
UEFI/BIOS versions for the computer, and, for upgrading it as needed.

A Celeron should be able to run i386 Debian. But the amd64 might be a
better use of its capabilities.

I understand from the link that it has a 64 bit Celeron J4105 CPU.
So its EFI would want an "amd64" ISO.

You could try with
  
https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-11.7.0-amd64-netinst.iso
and CSM disabled.
(Maybe it even begins to work with CSM if the firmware is brain damaged
enough.)

Can you perhaps point out a link to read that procedure?  Thanks!

My understanding is that Windows 11 computers have malware that is 
designed to prevent booting into anything other than the malicious 
Windows 11.


A procedure to get around the Windows 11 malware, and to be able to boot 
into Linux, has, I believe, been described on the Ubuntu Users mailing list.


My understanding is that, to boot into Linux or any other non-MS 
operating system, Windows 11 should be avoided like the plague that it 
is, and, that a computer with the Windows 10 OS should be obtained, 
rather than the malware that is Windows 11.


Windows 11 also, in the malware that it is, proscribes software that 
runs on Windows 10 and earlier versions of Windows.


The best use for a Windows 11 computer, is to use it as a projectile. 
Such computers are not even substantial enough to use as boat anchors.

This way:

 $ dd if=debian-11.7.0-i386-netinst.iso of=/dev/sdd bs=4M; sync

As I said, another machine of mine boots regularly into it, so it must be ok.

No message: it simply boots into Windows instead of the USB drive that I chose
in the menu.

It might help if you identified the new machine.

You might also check web sites related to Linux on that manufacturer's
products. E.g. thinkwiki (https://www.thinkwiki.org/wiki/ThinkWiki) for
Lenovo/IBM machines. Or https://linux-hardware.org.

Hi Rodolfo,

What model of machine is this - and how new?

How did you write the image to the USB stick?

CSM is probably not needed. USB boot *should* work but there is a
way of forcing boot only to Windows 11 in some machines. (I had this
on a relatively new T490).

Does it show any messages?

Hi, Sophie.. While you're waiting for others to respond, am typing to
say I just went through this a couple days ago. Our situations are all
so different so this is a recap of what happened for me.

In *my* case, something unknown changed a BUNCH of (but not all) top
level root directory permissions. I found out by accident while trying
to mitigate the first errors I encountered.

At some point, systemd was referenced and was freaking out that it had
lost permissions. That's when I ran "ls -ld /*" and received e.g.:

lrwxrwxrwx   1 root  root  7 Feb 11 14:26 /bin -> usr/bin

drwx--   8 root  1001  4096 May 16 22:19 /root

1001 is the username I was on when the incident occurred. That /root
change is odd because it only changed one of them. Even odder is how
whatever did this made only partial permission changes instead of
altering all child directories under the top level parent "/"
directory.

First sign something was wrong was that I suddenly couldn't log onto
the Internet. Prior to that, everything else worked as expected.

Then I rebooted and landed at an "sh" prompt. A second or third reboot
landed at that dreaded kernel panic screen that only shuts down for me
by punching the hardware ON/OFF button.

I had also done an update/upgrade a few hours before. Newest program
added was Einstein after a different Debian-User thread reminded me it

Hi, Sophie.. While you're waiting for others to respond, am typing to
say I just went through this a couple days ago. Our situations are all
so different so this is a recap of what happened for me.

In *my* case, something unknown changed a BUNCH of (but not all) top

to mitigate the first errors I encountered.

At some point, systemd was referenced and was freaking out that it had

After thinking about it again, I take that back. I THINK Adobe
affected only the directories it touched, not all "/" directories,
which would partially match how whatever changed mine didn't change
all the child directories.

It still doesn't explain how e.g. /root became "root 1001" instead of
"root root" permissions. My impression as someone who reported this
years ago is that someone has figured out how to take the damage to a
new level.

Hi, Sophie.. While you're waiting for others to respond, am typing to

In *my* case, something unknown changed a BUNCH of (but not all) top

At some point, systemd was referenced and was freaking out that it had

1001 is the username I was on when the incident occurred. That /root
change is odd because it only changed one of them. Even odder is how
whatever did this made only partial permission changes instead of
altering all child directories under the top level parent "/"
directory.

First sign something was wrong was that I suddenly couldn't log onto
the Internet. Prior to that, everything else worked as expected.

Then I rebooted and landed at an "sh" prompt. A second or third reboot
landed at that dreaded kernel panic screen that only shuts down for me
by punching the hardware ON/OFF button.

I had also done an update/upgrade a few hours before. Newest program
added was Einstein after a different Debian-User thread reminded me it
exists.

In case it helps narrow down a culprit, the last four apt-get actions
I performed between 2023.05.15 and 2023.05.16 are:

 END SNIPPETS FROM /var/log/apt/history.log 

The affected partition is still here, but I didn't have time for
fighting with it. I debootstrap'ed onto another partition, installed a
ton of favorite programs (not Einstein), ran "ls -ld /*" on the new
partition, and all has been well...

So far.

PS I reported this exact kind of thing to Debian Security a number of
years ago. I was "blown off", shown the cyber door. The PRIVATE email
I sent them had explained the situation two different ways to help
expedite their receiving end's grasp of the repeatedly reproducible
direness of what happened.

In last year or so, someone else got credit for reporting a part of
the same thing I reported years ago. I don't remember what was left
out, but whatever it was, someone else has possibly figured it out...
so that it's not just Adobe perping it this time.

And they're perping it in a different way. Adobe had gone straight
down the line and changed everything directly under "/" to a third
party username. No root, no 1001 for that one back then.

Booting Debian from NFS (using EFI PXE GRUB)

[tuxifan]

Hey!

As kind of a network-wide fallback system (and for some diskless computers in 
our network) I'd like to set up EFI PXE boot for a simple Debian system. 
However, I have only been able to find very sparse and possibly outdated 
information on how to actually tell the kernel/initramfs to mount a NFS 
filesystem as filesystem root. I even asked Chatgpt, and it replied with its 
usual hallucinations, unable to provide real links to source of information.

This is what my TFTP root currently looks like:

├── grub
│   └── grub.cfg
├── grubnetx64.efi
├── initrd.img (Generic Debian Testing initrd.img)
└── vmlinuz (Generic Debian Testing vmlinuz)
(1 directory, 4 files)

And my NFS root currently isn't much more than the result of a Debian Stable 
debootstrap.

Do you have any tips and ideas on how to get Linux to mount that NFS root as 
the filesystem root?

Thanks in advance
Tuxifan

Debians,

I'm trying to pxe boot a client with UEFI BIOS to no avail.

Everything works with legacy BIOS but if I use those two lines in my
dnsmasq.conf:

"dhcp-boot=bootnetx64.efi
pxe-service=X86-64_EFI, "Boot UEFI PXE-64", bootnetx64.efi"


the client gets an IP but no file are sent.

I'm at a lost on what to do to PXE boot a EFI client.

Does PXE booting of EFI clients require other ports than 69 UDP and 4011

Any pointers is appreciated.

I think this was your issue. pvshim is PV-inside-PVH. So the
hypervisor that starts your guest kernel is in PV mode, which as

Modern Linux kernels should either be run in PVH or HVM mode under
Xen. pvshim is strictly for older guests.



Yes, thanks. I understand now. I was actually running the 64 bit kernels
this way too - a bit of googling and I worked out that I should be using
the grub-i386-xen_pvh.bin kernel for 64 bit too.

The old pv grub kernel had to be different for i386 and amd64 but the
pvh grub kernel can be used for both - which simplifies things.

Thanks for your help - I was completely stuck and duckduckgo wasn't
giving me any clues but as soon as you said pv had been removed my
'enhanced' searching and experimenting put me on the right track.

The Linux kernel removed PV mode 32-bit Xen domU support at version

Making the domU multiarch and booting it with an amd64 kernel while

This is a minimal install - I've now tried both as a fresh install and
upgrading from buster but I always get this same failure. The 4.19
buster kernel boots bullseye fine. Dom0 is bullseye.


I cannot find anybody else reporting this so either I'm doing something
wrong, doing something that is no longer supposed to work, or nobody is
using xen any more...


Assuming there isn't a simple solution, what do people think is the best
way forwards:

1. Convert to using KVM instead - this seems to be more popular now -
when I started using xen I don't think it even existed.

2. Convert my few remaining i686-pae images into amd64 images.

Will KVM boot a 686-pae kernel? If not then it seems I need to do 2
first anyway.


My processor says it supports VT-x although I don't see that in flags -
perhaps because I'm looking in a dom0? So changing to KVM might need new
hardware...

Re: "Failed to start Create System Users" when booting Debian 10 rootfs from NFS mount.

Hi,

A suggestion: we've had issues in the past, where on NFS root the issue 
was that setting "Linux Capabilities" (setcap) fails, because NFS does 
not support the extended attributes to store them.


Perhaps that is your issue as well?

Hi,

I'm trying to bring up the Debian 10 root file system on an ARM SoC

And this is the only error message printed out. The board went all the

Good research, and "thank you" from a systemd-abstainer, that's
my way to learn, after all :)

I'd contribute my hunch: perhaps systemd is trying to get sysusers
up "too early", before the root file system is pivoted-in?

Feeding my search engine with "NFS root" and +systemd turns up a
bunch of interesting suggestions (e.g. network has to be up before
NFS has to be mounted, etc:).

Good luck... and tell us what it was ;-)

That's enough to get you started down the rabbit hole(s).  You should

I'm trying to bring up the Debian 10 root file system on an ARM SoC board.
When the rootfs was in an SD card the board worked well. When I put the
rootfs on an NFS server and tried to boot the board through NFS mount, it
reported error through serial port:

[FAILED] Failed to start Create System Users.
See 'systemctl status systemd-sysusers.service' for details.

And this is the only error message printed out. The board went all the way
to login inputI, but I could not login with any of the preset accounts
including root (because no users have been created as it suggested?), and I
didn't see any way to run commands to check system status for details.

So how is the process "create system users" performed when Linux/Debian
starts? What can be contributing to this error?

Any suggestions would be greatly appreciated.

That is correct.  I did install in UEFI mode.

If this is the case, you should be able to fix the problem
via BIOS setup, to select the (presumably Debian) entry that is probably there 
to
select as top priority.
After the BIOS update I mentioned the only boot choice was Windows which 
is why I figured some part of the GRUB stuff had been broken or deleted.

Alternatively, having executed mount -a after chrooting,
running efibootmgr should allow reorganizing the priority list to put your 
choice
at the top, or to add a new one if the one you need to be first is missing.

man efibootmgr


That didn't seem to work but as I was trying to figure out why I 
discovered I must have missed where rescue mode was telling me to mount 
the partition that must have had the EFI stuff I needed.  I can't give 
precise information but I was able to reinstall GRUB from Rescue mode 
and now all is well!


Thank you very much for your help,

Paul

booting from install usb

[Paul Scott]

Greetings,

I haven't done serious system work for many years.

I let my laptop update its UEFI BIOS which of course zapped GRUB.

I am in rescue mode from the USB stick used for install and have mounted 
the root file system and done:


chroot /mydisk (where my root file system is mounted)

I am not sure where to install GRUB with grub-install

I initially installed on a Windows 10 system.

.I have:

/dev/sda1 which is empty

/dev.sda2 which is "ef EFI (FAT-12/16/32)"

/dev/1p[1-7]  the first of which is EFI System followed by there MS 
partitions and the last three are my Linux partitions.


TIA for any help (I have been searching the web for quite a while 
without success beyond the above),


Paul

I did this last fall, I may still have notes with links somewhere. I
think I did resize the EFI and recovery and the main Windows partitions
to have enough space for Linux system and boot files on the respective
partitions. I had no issues with the Debian installation even though it
was my first UEFI machine.

My desktop upgrade this winter was second UEFI experience and there
things were more complicated since I converted it from BIOS boot to UEFI
boot and it has Windows 10 and Debian and Arch. Windows didn't actually
survive the changes in HW, no problems with the actual conversion
though.

As for secure boot, I tried it with the laptop and it worked fine,
except Linux (or at least Debian 11) doesn't yet support hibernation
with secure boot so I turned secure boot off.

You've had the usual variety of suggestions, all of them good in
slightly differing circumstances.

Here's a case history:

I bought a 'refurbished' netbook containing Windows 10 about two years
ago. It had a hardwired 32GB SSD (not actually large enough for Windows
to do its out-of-box first upgrade without the temporary help of an
external USB drive) and internal space for a real laptop hard drive. The
installation was UEFI.

I was prepared to wipe Windows and start from there, but just for a
laugh I ran the Stretch netinstall and told it to install to the new
additional hard drive.

Well, the damn thing created a perfect UEFI dual-boot. Just like that.

Sadly the effect was spoiled somewhat when I later upgraded to Buster,
which stopped the computer booting at all without manual intervention
to the UEFI boot menu, and even then would only boot to Windows. I
spent quite a lot of time (including a fresh install of Buster) trying
to fix this, but to no avail. To this day, if I boot into Windows, I
then need to used a netinstall disc in rescue mode to get grub booted
again.

To complicate matters, the netbook UEFI implementation has at least
two problems: it implements NextBoot but not DefaultBoot, and when I
edit the UEFI boot menu, on its next boot it restores the Windows drive
to the default entry (and then fails to find it!) so it is entirely
possible that with a decent UEFI firmware, there might still not be any
problem. I'd love to know how Stretch got it right first time, though.

So I'm adding a warning here: do not assume the UEFI firmware of this
laptop is implemented correctly. Spend some time searching for UEFI
issues with the model before beginning work. My netbook is an Acer, and
apart from this issue is a wonderful machine, but Acer is notorious for
BIOS/UEFI issues, and slow to issue upgrades, if ever.

You are right, but OP asked for "newbie instructions" on how to multiboot
Debian and Windows.

AFAIK it is up to firmware to support MBR or not. Even more fun: firmware
_may_ support any filesystem including NTFS or ext3, but every modern
firmware _must_ support GPT and Fat32.

A "few" years ago,  I acquired an HP Tower with Windows 8.1 on it.  I
invested in a 1 Terabyte External "spinning rust" drive, connected via
USB.  I installed xubuntu on it and fixed Bios and UEFI to allow USB to
boot. This included disabling Secure Boot, by the way.

I ran it that way for a couple of years,  before shrinking Windows and
making use of the, rather delicious internal Hard drive space.   (Windows
was, eventually upgraded to 10, using one of Microsoft's "free offers", but
that's a different story.  And, when I recently asked about upgrading to
Windows 11, Microsoft simply laughed at me).

I am still using that Infrastructure, but without the external USB, and
with Debian Bullseye being the primary system.

As mentioned earlier, I disabled Secure Boot to even be able to boot
External USB but, on one of my laptops, made use of the shim file someone
else mentioned. And yes,  Debian suports Secure Boot, as noted on the
previously mentioned Debian Wiki article.

Good luck!

Hi,

i have to add some technical nitpicking for the archives:

IL Ka wrote:

  https://uefi.org/specifications
current is UEFI Specification Version 2.9 (March 2021)
  https://uefi.org/sites/default/files/resources/UEFI_Spec_2_9_2021_03_18.pdf

It may also be partitioned by an MBR partition table.
(UEFI 2.8, 5.2.2 OS Types:
 "0xEF (i.e., UEFI System Partition) defines a UEFI system partition."
)
Debian ISOs boot from USB stick by such an MBR partition.

In GPT the EFI partition is specified to be marked by type GUID
12A7328-F81F-11D2-BA4B-00A0C93EC93B.
(UEFI 2.8, Table 23 Defined GPT Partition Entry - Partition Type GUIDs)


Have a nice day :)
