I used to use pc a few years ago that had windows XP installed on it (SATA hard drive). Lets call this hard drive Hard-1.
I got a Dell Optiplex 380 recently. This has also come with a SATA hard drive. Lets call this hard drive Drive-2. This has windows 7 installed on it.
I wanted to copy some data from Drive-1 (the old one, with XP installed) into Drive-2 (the new one, with windows 7). I unplugged the optical drive and plugged in Drive-1 in it's place.
Now there is a weird problem.
If both drives are connected (Drive-1 on optical drive port) then the computer will allow me to boot ONLY from Drive-1. Windows xp starts loading and then hangs up in the end.
If I unplug Drive-1 then the computer will boot from Drive-2 (the normal way). But then if I plug in Drive-2 in running computer, it will not get detected. I have tried trying to boot from Drive-2 and immediately then plug in Drive-1 before windows 7 finished booting, but this still doesn't show Drive-1 after the desktop appears.
How can I get to boot from Drive-2 AND see the contents of both drives after windows has finished loading?
