For you computer-minded folk, I have a question:

I have two hard drives on my computer, my old salvaged one as IDE and my new SATA one. Both of them have a bootable OS, but I use the SATA one as my main OS. The BIOS preferentially assigns an IDE hard drive to C and the SATA one to D. Somehow my computer lost connection with the IDE drive, and apparently the BIOS stores boot information on it. I wasn't able to boot to any OS even with the the SATA drive detected and working.

How the heck do I fix THAT? And by fix, I mean transfer all bootable information to the (newer, faster, serial) SATA drive?
