I was looking again at this reference,
and I really don't think it is very good,
or likely to be helpful to someone trying to boot from hard disk.

That reference is(was) particularly important for showing explicitly
that you need the leading slash {/) for the directory.
The leading slash needed starting in F10,
prior to F10  no leading slash, which caused much confusion
when attempting hdinstall starting from F10 (see bugzilla ref below).

In the first place, I would have thought that almost anyone doing this
would want to (or need to) avoid CDs or DVDs altogether,
by abstracting vmlinuz, initrd.img and the images directory
from the ISO file,
and adding a stanza to grub.conf to boot from these.

There are no instructions for doing this, as far as I can see.

Well, you seem to have figured it out, congrats!
May I ask, just where did you find the instructions re install.img,?



I myself depended heavily on the references following;
not much on the fedora site


hdinstall was thoroughly discussed in these 3 refs:

1)

I think I first came across it when installing Fedora-10,
which I believe was the first distribution
where it was necessary to abstract install.img 
as well as vmlinuz and initrd.img .

I guess I would first have read of it here,
in a posting to this list/newsgroup.

the installation image for Fedora is the .iso file, when doing the

The installer wants you to specify the disk partition where the .iso
is, AND the full path to the directory.  So, if it's on your /home
directory (on partition /dev/sda5) and in your /home/tim/images
directory, then you'd tell the installer:

/dev/sda5   (for the partition)
/tim/images (for the directory)

All those do is give you enough of a system to boot and run the 
installer.  They do NOT include the items necessary to install Fedora.

For that you need the Packages directory.


There are no instructions for doing this, as far as I can see.
The implication seems to be that the user is running a Fedora CD or DVD,
and then wants to install from hard disk,

Not at all.  CDs and DVDs are much slower than hard drives and are
subject to all the possible errors inherent with non-contact, removable
media (scratches, dirt, etc.).


If you can boot from CD or DVD, why not install that way?

Actually, the whole Installation Guide, while beautifully produced

The portions of the manual dealing with network or hard disk installs
are intended for more experienced users.  The vast majority of newbies
will simply burn the ISO image to a CD or DVD and boot that.  Anaconda
is pretty simple from there.

Even at that, a lot of newbies burn the actual ISO file to a disc
(ending up with a disc with one file on it), when they're supposed to
use the ISO file as a disk image to burn the disc.

If you can find a way to make computer software installation absolutely
foolproof, yet accessible to everyone regardless of skill level or
experience, then PATENT IT QUICKLY!  You'll make a mint!

Where the hell's the 'any' key?  I've looked and looked and can't find
it!

Thanks.
But since there actually is a file called install.img
involved centrally in this process,
to use the term installation image for another file
seems bound to cause confusion.
Why not just call it the ISO file, or .iso file?

I've been doing hard disk installs for quite a while now, and
since fedora 10 (I think it was) you do indeed need the
install.img file from the iso.

Here's the procedure I have now used successfully many
times:

1. Get the iso image stashed in a directory which contains
no other .iso file on a partition that will survive the
install. Let's use a specific example from my system.
I have a external USB drive mounted at /backup with
the disk label BACKUP and lots of iso images stashed
in /backup/iso-images subdirectories.

cd /backup/iso-images/Fedora-12-x86_64-DVD/
mkdir mnt
mount -o loop Fedora-12-x86_64-DVD.iso mnt
mkdir images
cp mnt/images/install.img images
mkdir /boot/f12
cp mnt/isolinux/initrd.img /boot/f12
cp mnt/isolinux/vmlinuz /boot/f12
umount mnt
rmdir mnt

Now edit the /boot/grub/grub.conf file and add an entry
like this (adjusting the hd0,4 or whatever appropriately):

title Install Fedora 12 x86_64
root (hd0,4)
kernel /boot/f12/vmlinuz 
repo=hd:LABEL=BACKUP:/iso-images/Fedora-12-x86_64-DVD/
initrd /boot/f12/initrd.img

Things to note: It is much simpler to have the install.img file
extracted in the images directory next to the iso image than to
provide separate boot parameters to say where it is.

Using the LABEL= syntax to specify which disk seems to be
essential as well, since anaconda appears to quite frequently
enumerate the disks in a different order than the current installed
linux does (so you may think it is /dev/sdc, but when anaconda
boots, it is really /dev/sdb, then it can't find the files, etc).

Now all you have to do is reboot and pick the Install item
when it gets to grub, and off you go...

 The install.img is placed in a images directory.
 There are strict requirements on where that images dir is to be placed;
 I am not sure, but i think the OP did this part correctly.
 Where he might be going wrong is how he interacts with Anaconda,
 as I tried to explain in  my earlier reply

As I mentioned in a post above, this worked fine
when I moved the Fedora ISO and the images directory
to the top level on another partition.
I'm not sure what I did wrong before.

 /mnt/Fedora/isolinux/* /boot/Fedora-12/ -

 This is the entry I have added to /etc/grub.conf :
 -
 title Upgrade to Fedora-12
 root (hd0,1)
 kernel /Fedora-12/vmlinuz ro
 initrd /Fedora-12/initrd.img
 -

 Now when I boot into this, all goes well until I try to install from
 Fedora-12*.iso when I the error Device /dev/sda6 does not appear to
 contain an installation image.

 Am I doing something wrong?

You don't give enough detail.
What you have shown I think looks ok
(would have to check old notes to be sure)
The missing information is just what exactly did you enter into
the anaconda gui.

I have no f12 experience, but
in my successful f11 hard disk install
I did this two ways
1) using repo= option in kernel line:

#title Install Fedora 11   repo=hd:/dev/sdb1:/root/diso   reordr
#root ...
#kernel /boot/f11/vmlinuz noselinux  repo=hd:/dev/sdb1:/root/diso
#initrd /boot/f11/initrd.img

2)not using the repo= option

#title Install Fedora 11  h NO repo=
#root ..
#kernel /boot/f11/vmlinuz noselinux
#initrd /boot/f11/initrd.img
#here I have to pick /dev/sdb1  and /root/diso for directory

you enter these in the anaconda gui.
The leading slash /   in  /root/diso is essential.

This is documented on the fedora site somewhere;
the leading slash requirement started with f10.
Are you operating from f11? or earlier?

The entire process for hard disk install,
including detailed instructions for the images directory,
was subject of a long thread Mike Cloaked and Tom Horsley,
I think in Nov 2008, including a bugzilla re the leading slash.
I don't have that bugzilla ref right now.

If my experience is any guide, if you follow the
instructions in that ref, it should just work.

I don't know for certain, but the only time I've ever tried this was
on RHEL and the ISO file had to be on the root of the partition. So I
think that means you should try moving it to
/home/Fedora-12-i386-DVD.iso on the assumption that /dev/sda6 is /home

I think I tuned in late here, but I'm not clear what you're trying to
do.  If I'm reading this correctly:

1. You're running Fedora from hard disk
2. You're then loopback mounting an ISO image of F12
3. You're trying to install from that loopback mount

You can't install a new Fedora on top of an already running Fedora to my
knowledge.  The install from DVD or LiveCD are special instances and
Fedora is not running off the hard drive in those cases--it's running
in a RAM disk.

If you're trying to install via a network install (NFS or HTTP), then
the ISO image itself is what you point at, not a loopback mount of it.
The installer wants to see the ISO image itself, not the files in it.

When I've done network installs in the past, it was possible to do it
either way (dependent on what sort of network install you were doing).
But I found it much faster to install from ordinary files on a drive,
there seemed to be an enormous memory and processing overhead on dealing
with a large ISO.  Sometimes it'd be a complete show-stopper.

One can only guess, but...

you put the images directory and Fedora12.iso in /home/tim ? 
and /dev/sda6 is /home ? 

Then when you boot you should specify both the drive and the path to the 
images directory. Don't remember if you must specify /tim or just tim. 
The point is you need to specify the path to the images directory, not 
just the drive.
