Re: 2nd hard drive question
If you want to completely get rid of the one OS...then download Killdisk/burn it. Put it in the try, shutdown, unplug the HDD that you want to keep, and then start up. Wipe the drive (will probly take about an hour, depending on the size of the drive that is). Then you can shut down, plug you rmain drive back in, and then format the newly-erased drive as NTFS, or do whatever you want with it.
I've done this several times...its a lengthy process but works.
Edit: May have misread the question... If you wanna do that, you can just set the drive that you want as your main drive as the primary boot drive in the BIOS, and then it should be fine. I have XP on one drive, and Vista/Ubuntu dual-boot on another drive. I use XP mainly, so I have that as my primary boot drive, and if I wanna boot into either of the others, I just go to my boot menu, and select to boot off of that drive.
