If Ubuntu or GRUB is on another HD, it's best to unplug it so it doesn't interfere with repair.

If necessary mark Win7 partition active, then run Startup Repair up to 3 separate times as shown in the tutorial Derek posted: http://www.sevenforums.com/tutorials/71432-partition-mark-active.html

It's always a lot better to put Ubuntu on a separate HD to boot via BIOS boot order or one-time BIOS Boot Menu key.

This way GRUB doesn't have a chance to corrupt Win7, as it frequently does (like daily here).
