Can't install grub during .7.1 cd install

During my .0.7.1 install, when I get to grub, I get an error that grub could not install, and it tells me to see the output in tty5.  In the output console it says
"grub> root (hd2,0)"

"Error 21:  Selected disk does not exist"

"grub> setup (hd2)"

"Error 12: Invalid device requested" 

"grub>quit"

Something along those lines.  Now, I've been trying to solve this for hours, as it wasn't happening before with my 0.7 base cd I was trying to use to install before, but I had other problems with that with udev when trying to upgrade...

For info, my hard drive IS /dev/hdc  so I believe hd2,0 is correct, but I tried changing it all the same to hd0,0 and hd1,0 and both times it still seems to try to use hd2 because I get the exact same errors.

I'm tired and thinking of giving up on Arch.  I don't want to, but I'm frustrated at this point, after searching through documents for answers, and asking many people on irc(who were helpful, but all ended up leaving with my problem unable to be fixed) so any help would be greatly appreciated.

I got the same error, but grub was actually installed correctly!! Have you tried to boot normally after the failed installation?

Yes.

It does a "Search for Boot Record from IDE-0..OK"
"GRUB _"

the "_" being a blinking cursor where I can't type anything.

It just hangs there

Ok, then it may have been an old version og grub on my system and it was not destroyed by the arch installer. But  you can anyway use an other instll-cd to install grub.

Solved

After fixing the device set up in comp so that hdd was /dev/hda, and then running:

***
dd if=/dev/zero of=/dev/hda bs=512 count=1
***

from command off cd to clear MBR, it worked

***warning: that command could lose data, use at own risk

THANK YOU to rann in #ArchLinux on freenode for all the help
