I had Vista Ultimate installed on one of my computers and it was working fine, until my dad did something that messed it up.

Because of this, whenever I tried to boot windows, it would ask for the installation disk.

I tried to use the installation disk to repair the computer to no avail. So then I decided a full OS reinstall would be the best way to get the computer running again.

When I tried to do this, at first none of the drives had adequate space (it asked for six-odd gigs of space) so i reformatted one partition. When I tried to install into that drive, it gave me an error, saying no suitable drive was found.

I don't know what to do. Any help would be greatly appreciated.

Thanks in advance,
Karan
