GRUB has been wiped..(Solved)..

GRUB was wiped by Win 7. Totally forgot about it when i was installing. I have tried to restore it myself but im just getting more confused. Right now the Win 7 bootloader is working fine but i want to get into Arch soon.

I have tried the stuff on the arch wiki -Reinstalling GRUB, but its not working . I keep getting an error 17 "Cannot mount this partition". All i can tell so far is this:

1) Its the second partition in my boottable (/boot). So that makes it (hd0,1) right? (in accordance to grub)
2) Its dev name is sda4
3) I only have one hard drive.

I have used the arch 2009.02 images to bootup the live system and done { grub - root (hd0) - setup (hd0,1) }. This gives no stage1 files found. Could this be because both my /boot and / are ext4?

Can someone please help me out. I really need to get Arch running again.

If you're certain the partition is the #2 one, it should be /dev/sda2 not /dev/sda4 - your partition table is screwed up.
Do this:

Boot w/ the arch cd, log in as root, then

# fdisk /dev/sda

Once you're in fdisk, enter e[x]tra/expert mode, [f]ix the partition order, then [w]rite the table and exit. You'll do this by three keys, X, F, W. Now exit fdisk.

Now reinstall grub on your MBR:

# grub
grub> root (hd0,1)
grub> setup (hd0)
grub> quit

You'll need to add a chainloader line to your /grub/menu.lst to get into windows 7...
