[solved] Messed up MBR, help :)

Sooo... I did something rather stupid. Long story short, I reinstalled Windows 7 on my other patition and I lost GRUB. Why did I reinstall? Because the Arch partition was the main one where the bootloader was located so I couldn't get in Windows 7.

Here is my configuration:

/dev/sda1  ~20GB Arch partition (not seen in windows 7)
/dev/sda2  ~70GB NTFS Windows 7
/dev/sda3  2GB swap

I can't install GRUB from the Arch installation image as it says /dev/sda (tried /dev/hda as well) not found. FDISK does find it, though and sees everything.

I used 1 hard drive, divided in two. What was C: is now /dev/sda1, what was D: (now is C: in Windows 7) is /dev/sda2.

How can I get GRUB back without reinstalling Arch (not that I have anything important, but don't want to go through hassle again)?

Cheers.

GRUB 1 from the installation image.

setup (hd0) cannot find the drive.
setup (ho0,0) works, but it's pointless as Windows 7 holds the MBR.
grub-install /dev/sda doesn't work as it says not found.

I think I will just reinstall Arch, it's my fault that I didn't set up Windows properly before installing Arch.

Any other helpful thoughts?
