All: I have read a few post on how this is done and few things one needs to look out for... In my situation I have 2 hdd for my dell latitude, one running WinXP and the other Fedora Core 2, I was swapping HDD before. Just yesterday I bought a media bay so I can plug fedora Core 2 as a second hdd. I was wonderding how to configure without formatting fedora core hdd to be able to chose which OS i want to boot to when I start the machine. Any pointers ? Thanks, -B
