[SOLVED] GRUB Problem with LVM

Hello,

Okay, so I followed the steps here, and I end up with an Error 17: cannot mount selected partition.

This is the breakdown of my setup
sda - 250GB
-- sda1 - 250 GB LVM
sdb  - 80 GB
-- sdb1 - 80 GB LVM
sdc - 40GB
-- sdc1 - 250MB, bootable Linux filesystem (for GRUB, since it can't handle anything LVM)
-- sdc2 - 39.3 GB LVM

All of the LVM partitions are clumped together to create one large Volume Group labeled VolGroup00

In VolGroup00, I have a few logical volumes:
20GB /
20GB /home
1GB swap
250GB /storage

/boot is supposed to be mounted on /dev/sdc1. My GRUB menu looks like this:

# (0) Arch Linux
title  Arch Linux
root   (hd2,0)
kernel /vmlinuz26 root=/dev/mapper/VolGroup00-lvolroot resume=/dev/mapper/VolGroup00-lvolswap ro
initrd /kernel26.img

I dunno what I did wrong. /boot is on a normal, bootable Linux filesystem, and I don't think I screwed up while following the wiki. =/ Any help is appreciated.

Some more info:

Re: [SOLVED] GRUB Problem with LVM

Nevermind. Turned out that the root in the GRUB menu was (hd2,0), when it should be hd(0,0)

What's weird is that the hard drive with /boot is on the third harddisk, thus hd(2,0). But whatever, it works.
