Grub Loading Error 22

[darkside]

OK i have three hard drives, an 80gb with vista on. an 80gb, split into 2 40gb partitions. The first has Win7, and the second has ubuntu. Then i havee a third 500gb disk with my files on.

I Got all the partitions sorted out first, and got my files on to the 500gb, i formatted the w7 partition from inside vista, ready to take win7 on it. i left the other 40gb as 'raw'

I Then installed vista, all was good. I could turn on the comp, and i could choose between the two. After id done that i installed ubuntu on the 'raw' partition. (the installer formatted it to ext3 or w/e its called)

The installer then rebooted my system and left me with 'grub loading error 22'

Now from reading round the net it seems this means 'wrong partition' so i thought it might me trying to load the wrong drive first in BIO or something, but ive tryed the vista drive, and the w7/linux drive and primary boot devices and had no luck.

What do i do now? Im guessing im gonna have to use the ubuntu live cd and edit the files some how, but i dont know what file to edit, or how to edit it :/
Any help would be appreciated

You need to take a look at these files:

/boot/grub/menu.lst

/boot/grub/device.map

menu.lst is the grub configuration file and device.map will tell you how grub is mapping your hard drives with respect to menu.lst. If you post those files here, we can probably figure out what's going on and make the appropriate changes.
