GRUB Issues

?Mike: I have an old computer with two hard drives. I have Windows XP SP3 on one drive and I had Ubuntu 9.04 that had upgraded to, I believe, 10.04. A while ago, I bought issue 11 of Ubuntu User to get a newer version of Ubuntu. When I tried to upgrade, it said I had "unresolved issues" and would not upgrade, so I set it aside for a (long) while. This week, I'm on vacation so, I decided to try it again.

I unplugged the Windows drive, put the Ubuntu 11.10 disc in the drive, and loaded it onto the drive that had previously been the Ubuntu drive. I did all the updates but when I plugged the Windows drive back in and started up the computer, when it gets to the GRUB loader, I get Error Message #15 . If I unplug the drive with Ubuntu so that the Windows drive is the only drive, I get Error Message #21 . My Windows drive is totally inaccessible. Can you help me get the GRUB loader back working so I can have both drives and both systems? Thanks so much, Dave

AFirst, try running Boot Repair from a CD/DVD/USB [1]. This utility should be able to detect your Ubuntu and Windows installations and repair your GRUB settings to make them work (Figure 1).
