GRUB fails to boot any OS


I am inexperienced in using Linux, and just installed Ubuntu 10.10 on an external hard drive. I didn't want to mess around with re-partitioning my hard drive, which has Windows 7. I figured that I could just run Ubuntu from the external, and if it gave me any problems with Windows, which I unfortunately need for work, I could just unplug it and boot normally. However, GRUB appears to have installed some component to the local hard drive. Whenever I try to boot from the local hard drive, I get this error message:
"error: no such device: 8b84f351-7770-4908-b12f-0cbd31bc3662
grub rescue> "
Another thing is that in the boot menu, only the CD/DVD drive and local hard drive are options, it won't even register the external.
Any suggestions on what may have caused this error? I saw from other posts that GRUB doesn't like multi-drive systems. Also, would it be possible to delete GRUB from my system, then allowing Window's MBR to take over? Thanks for any help.

If you want to remove Grub, and have windows re-write the MBR -- thus getting rid of Ubuntu...

Code:
Boot up off of the Windows 7 CD
"Repair your computer"
Command Prompt
cd \boot
bootsect /nt60 C:\

Thanks, I think I'll do that. I don't have a Windows 7 repair disk, so for a temporary fix, I just used Ubuntu on a pen drive, copied the Grub folder from 'boot', put it inside Windows' boot folder, and problem (sort of) solved. Thanks!

Its actually just a Windows 7 install disk that will do this.
