GRUB Fails to Boot Arch Linux

After 3 tries to install Arch Linux, I think I'm finally close (the process of installing it on my eeePC was way smoother). The installer said everything was successful from package installation to GRUB. I reboot, select Arch Linux from the GRUB menu, and got this error:

  Booting 'Arch Linux'

root    (hd2,0)
 Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz26 root=/dev/disk/by-uuid/a868aa81-ced0-4c38-af20-5a0f6af356da ro

Error 15: File not found

Press any key to continue...

So I boot up into an old Xubuntu installation on a different hard disk and mount the disk I installed Arch on. I do an ls and this is what I get:

root@rockstar:~# mount /dev/sdb1 /media/sdb/
root@rockstar:~# cd /media/sdb/
root@rockstar:/media/sdb# ls
grub  kernel26-fallback.img  kernel26.img  lost+found  System.map26  vmlinuz26

To me this doesn't look like enough to be bootable, but I could be wrong. Is this enough to boot? Did I install correctly? If so, then onto my next question. A few months ago I got a similar error from GRUB when I installed Ubuntu. I remember I had to fix UUID to get it to boot. What I don't remember is how to retrieve the UUID. Here is what I have in the grub/menu.lst file:

# Config file for GRUB - The GNU GRand Unified Bootloader
# /boot/grub/menu.lst

Thanks for any help. I'd really like to use Arch Linux on my desktop. When I put it on my eeePC netbook it was running GNOME faster than Ubuntu was on my desktop. That was the thing that made me want to totally switch over.

Regards,
Brad

Should be. Same as mine

Re: GRUB Fails to Boot Arch Linux

Grub and the kernel doesn't always see the discs in the same order. Try with root (1,0) etc

I tried switching it to all 3 of my drives and all of them returned the same error.

Thanks for the link and manpage. I found the UUID of /dev/sdb1 according to Xubuntu. I first tried that UUID in the Arch GRUB, which then returned the same error. Then I tried adding an entry to the Xubuntu GRUB using that UUID, tried booting from it, and got the error again. I don't know what to do now. Is there something I'm overlooking?

Re: GRUB Fails to Boot Arch Linux

File not found error means just that, it is not finding that drive

Either uuid is wrong or you have the wrong partition

Also check you have kernel installed? know it sounds crazy but worth checking

Re: GRUB Fails to Boot Arch Linux

Some days ago I had a "Error 15: File not found" that put me searching all day. It turned out that the problem was the partition
was formatted as ext4.

Now, that shouldn't happen with the arch GRUB version, which should be patched to recognize ext4.

Perhaps its just me, I have a GRUB only partition and the files on it could be to old.

Anyhow, just my 2 cents.
