HI again.

Well I have managed to get rc4 installed in UEFI mode, but it's not 
a nice process :)

The Qubes iso seems to contain two menus for EFI booting, but the
Dell XPS15 won't display them at all, hence there is no possibility
to edit the boot line and add the modprobe.blacklist option at bootup.

There are two ways I've found to overcome this - in one, I edited the
Qubes iso file before writing it to a usb stick, and the other was by
following the Lenovo troubleshooting link, 
https://www.qubes-os.org/doc/thinkpad-troubleshooting/

1. Binary edit the Qubes iso (I used gvim as plain vim could not
   handle the temp file!?!).
   Search for "i915.preliminary_hw_support=1" and REPLACE it with
   the string "modprobe.blacklist=nouveau   ".  This MUST be exactly
   the same length as the i915 string, so it add three spaces at its
   end.  ANY change in the length of the text line will damage the
   iso and it definitely won't work.

   This probably only needs to be done for the "qubes-verbose" menu
   options, but I didn't check this, I just replaced all the repeats
   of the string in the two menus.  There is a third menu for GRUB
   legacy, but I did not bother replacing them there.

   Then write out the iso to usb, and reboot.  Interrupt the Dell boot
   screen with F2 and select the UEFI usb boot option.  All should work
   OK.  (Qubes-check will fail because the iso has been edited, but
   the check option only appears when legacy booting.)

2. Or, follow the Lenovo troubleshooting guide at the link above, and
   create the usb and change the Label to BOOT and mount it.  I could
   not find the xen.cfg file, but there was a ".cfg" (can't remember
   the name) that contained the bootup command lines.  I replaced the
   option "quiet" with the modprobe.blacklist=nouveau string.  Length
   of the string does not matter in this case. Save the file, unmount
   the usb and try to boot from the it.

   It didn't provide an UEFI boot option on my DELL, but I was able to
   boot the "fallback boot on Anaconda" from my boot manager "refind".
   You may not want to go to the trouble of installing that if you are
   not multi-booting your laptop.  In which case, you only have option
   1.

Some of the problems with the Dell (apart from the nVidia device), are
that it seems to require that any EFI partition must have both the
correct partition type (EFI) and the specific EFI disk identifier,
otherwise its bios does not recognise an EFI boot partition.

Mike.

Think I had this working at one point too with the chainloader entry
listed in https://www.qubes-os.org/doc/multiboot/ .

Hi Yuraeitha,

Thanks for the explanation. I actually didn’t try installing in legacy on dell 
xps 15 but on an acer. 

Do you switch between legacy and uefi (dual booting) on xps 15?  And qubes4 
installed good in legacy?

I can both switch without issue, but also boot UEFI windows from Grub, which is 
something you may want to look into too. 

So as a basis you can use LegacyBOOS with Grub, and then point the Grub menu 
for Windows to UEFI/EFI boot, even though you're on LegacyBIOS initially. I 
don't remember the exact command-line in Grub, but it should be somewhat easy 
to do once you know the command-line to put in there. You might be able to find 
it quickly by googling it, this is not something exclusively for Qubes but all 
other Linux systems can do this too.

Also the inability to switch between LegacyBIOS/UEFI sounds like a bug in your 
UEFI? It shouldn't behave like that from just switching between LegacyBIOS and 
UEFI. Did you also make sure SecureBoot was enabled if Windows is relying on it?

Generally I believe, if nothing has changed (I'm no expert either), that 
LegacyBIOS is deemed more secure, because of the updates in the Kernel/Xen to 
prevent some of these security issues. Not all of them are fixed, but 
considering how fluky and poorly maintained/buggy UEFI is, it appears 
LegacyBIOS is the better option.

My understanding of the reason in the details, is that UEFI/EFI is less able to 
be fixed in the Kernel/Xen, or perhaps it's because there are so many unique 
UEFI distributions on every motherboard that it's just not feasible to keep it 
updated, while LegacyBIOS is much less frequently changing. Either way, UEFI is 
often buggy, and motherboard developers often care little about updating them 
properly, especially on the cheap models, but not always exclusively so.

I guess I’ll not jump into booting into legacy mode and having to mess up all

In 3.2, Qubes installed OK from an UEFI boot, but it installed itself
as the first and only boot option in the bios.  I was able to add back
the original UEFI boot options in the bios, and then use the F12 to
interrupt before boot, and select Qubes from the one-time menu list.

The best thing to do is to backup your EFI partition first, and make
a note of the bios settings regarding boot up and UEFI.

You should be able to boot in UEFI mode for Windows, but be able to
use Legacy boot for Qubes by interrupting the bios with F12 and then
selecting Qubes there.

But as I say, I haven't managed to get there yet.  I had to fix the EFI
partition this time too - for some reason the installer messes up the
EFI partition type on the disk, and the bios doesn't recognise any boot
partition.  I had to boot from a cdrom and use fdisk to change the EFI
partition type to EFI (which fdisk thought it was anyway!).

I had rc3 running fine, all in UEFI mode, so I think it will all work
eventually.

Good luck.

That's the same laptop as mine.  In the bios, there are a couple of
boot settings.  You need to enable Legacy boot in one of them.
It's not a disk thing.

Is there a way that I can set boot options through command line when I hit 
alt-tab it takes me to the command line with root@localhost

If I Ls then I can see boot folder along with others and boot folder contains

Use the Legacy boot, not the UEFI boot option.  Legacy runs grub to
diplay the options menu.  

I ought to warn you that I did not manage to finish the installation
yet.  Everything worked OK up to the boot loader install - that failed
and I don't know why yet.  Also the building of the "init ram disk"
(or whatever it is called - I forget) never finished, so I can't yet
boot into rc4.  Will have another go probably next week.

Mike.

You might need to use your Bios boot select options.  

When I first tried the installer, I got the same thing - it tried to
boot up straight into the installer, without giving me options.

I had to interrupt the laptop's boot phase (F12 on my Dell), and then
choose the option to make it boot from the usb in legacy mode I think.
Then the boot menu appeared.

Add nomodeset to your installer's boot options. If that doesn't work, try
the "Inst.text bootoption to start text Installation".

You need to add 'modprobe.blacklist=nouveau' to the kernel options
in the boot line.  Hit the Tab key on the be=oot menu line that you
want to use (I used the Check and Install line), then move the 
cursor to the 'quiet' word and append the above phrase.

Best of luck.

Is it trying to initialize a driver in the message immediately before the
first soft lockup? If so, try disabling the corresponding device from your

[qubes-users] 4.0-rc4 Install Help

[Shashank]

Hi I’ve been trying to install qubes 4.0 rc4 in my dell xps15
But I am not able to get the installation done. 

After I boot through the USB:

*starting graphic installer
*if installer doesn’t start type inst.txt to start text install
* not starting VNC because we don’t have network
* cannot start installation 
*PRESS ENTER

At the bottom of the screen I see
* PANE DEAD

and the message below goes on repeating
Watchdog: BUG: soft lockup - cpu stuck for 22s[xorg:1325]

I tried installing rc3
Rc3 shows the install menu but again has the same
Problem like mentioned above

Could anyone guide me to install it.
