Originally I had Windows 7 installed on my computer, but then I decided to install Ubuntu 10.04 LTS onto another HDD. Now I can boot into linux when I choose that HDD as the boot device, but now when I try to boot into the HDD that has Windows 7 on it, it doesn't work and displays this grub rescue prompt. I hope I haven't messed things up too badly...

Grub rescue>

So I'm GUESSING I've messed up this grub mbr stuff, and am wondering how I can get this WORKING so I can boot successfully into either operating systems. I'm not sure if this information is helpful, but I attached this fdisk information. The 500 Gb, and 1500 Gb are just for storage and have no OS on them.

Thanks for your help.

In Win Xp you can boot the CD then run the recovery console and execute the fixmbr command. If Win 2K does not include that otion, you may be able to run the fdisk /mbr command as found in Win9x using a Win9x boot disk.
