[solved] grub error

This is my first time trying Arch Linux. Install seemed ok but when I try to boot, I get the following:

Booting 'Arch Linux'

root (hd1,7)
Filesystem type is xfs, partition type 0x83
kernel /boot/vmlinuz-linux root=/dev/disk/by-uuid/2f0d5812-3cab-4e3d-988c-ebf2c2d6e180 ro

Error 15: File not found

Press any key to continue...

Now, I've double and triple checked the UUID and it definitely matches my '/' partition. (I did not make a '/boot' partition.)
(hd1,7) if I'm not mistaken should correspond to "sdb8" which is my root partition.
However, the filesystem is NOT xfs. It is EXT4.
GRUB is installed to the MBR of the same drive (sdb). (I have Windows Vista loader on the mbr of sda.)

I have no problem booting Windows from GRUB. But when I try to boot Arch, it fails with this error.

Any idea what I might be missing here?
Thanks

Show us the output of "fdisk -l".

Re: [solved] grub error

Can't copy-paste it all since I'm on a different comp, but here's the gist of it:

Device         Boot     Id    System

/dev/sda1       *         7     NTFS
/dev/sda2                  5     Extended
/dev/sda5                 83    Linux
/dev/sda6                 82    Linux swap
/dev/sda7                  7     NTFS
/dev/sda8                 83    Linux
/dev/sda9                  7     NTFS

/dev/sdb1        *        7     NTFS
/dev/sdb2                  5     Extended
/dev/sdb5                  7     NTFS
/dev/sdb6                  7     NTFS
/dev/sdb7                  7     NTFS
/dev/sdb8                 83    Linux

(Root is on the faster sdb drive. The other partitions are on the larger drive sda)

Unless I'm misunderstanding what the asterisk means, I think you haven't made your /dev/sdb8 bootable.

Re: [solved] grub error

Never mind. Sorry. Now that I'm looking at the fdisk output I realized it was trying to boot hda8 instead of hdb8. I had thought hda = hd0, and hdb = hd1. But apparently on my system it's the opposite. hd0 is hdb and hd1 is hda. (I guess hd0 is whichever grub is installed to?) Anyway I've got it sorted. Thank you both for your help.
