FC9, failed boot


Hi guys,

I previously had dualboot of Vista and Fedora9, as time passed I began hating vista, and reverted back to XP. So I formatted the vista partition and installed XP. This however removed the Grub boot loader, so I only had XP. I read some posts and figured out how to reinstall the grep using the fedora9 DVD and getting a shell by choosing the system recovery.

However, after doing this, the grep boot loader works fine, and I can change the menu.lst to whatever I want, but I seem to always get this:

mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Mount failed for selinuxfs on /selinux: No such file or directory.
switchroot: mount failed: No such file or directory

I'm not very familiar with the linux world as I've only been using it for about a month or so. So please stupify things for me if possible

I've read a few posts here concerning this exact problem, but I couldn't follow the suggestions (either because I didn't fully understand the explanation or that it didn't solve my problem)
Here are the different screenshots that I thought might be relevant:

Firs of all the the screen I get when it fails to boot:
[BOOT SCREEN NORMAL]

The same end, with silent turned off:
[BOOT SCREEN NONSILENT]
http://folk.ntnu.no/roaldf/LinuxProb..._nonsilent.jpg

The return of "fdisk -l"
[SCREEN FDISK-l]
http://folk.ntnu.no/roaldf/LinuxProb...4_fdisk_-l.jpg

The fstab file (which I'm not even sure of its purpose...)
[SCREEN FSTAB]
http://folk.ntnu.no/roaldf/LinuxProb...0896_fstab.jpg

Finally my menu.lst file:
[SCREEN MENU.LST]
http://folk.ntnu.no/roaldf/LinuxProb...8_menu_lst.jpg

Can anyone spot what the problem might be, and how I could fix it?

have a look at the partitions listed in fdisk -l and grub.conf
it looks like when you installed fedora the boot was in sda6
and from grub.conf it is trying to boot from ( hd0,5)-- this is sda6
so where is boot now ??
from fdisk -l it looks like it is know in sda1 (hd0,0)
try editing grub.conf to point to the new location (hd0,0)

Maybe you could explain the workings of the grub? Maybe there are some fundamentals I'm missing. If grub starts fine on startup (the menu appears with the different fields corresponding to the grub.conf), shouldn't this be ok?
Also, isn't it correct that it is trying to boot linux from (hd0,5), as it's here I had the /boot ?
Perhaps when I did the grub-install it transfered the necessary files to (hd0,0), is that feasible?

Maybe the fdisk is referring to the remains of the MBR from the xp install?
