This is just a theory, I haven't spent the money yet so maybe you guys can tell me if this is possible: I have a SATA internal hard-drive from a older HP Media Center Pentium 4 machine. It's a 500BG drive with XP and every driver for all the extra video-cards, wireless adapters, and what-ever other stuff was installed. The motherboard on that machine is junk so I am parting it out. I want to use this hard-drive to dual-boot my Macbook. I was thinking of buying a USB-SATA adapter (with power-source) and use this old hard drive to boot Windowz XP on my Macbook. First, is this possible? This is the first time messing around with dual boot (let alone buying a sata adapter). Second, will all of the drivers/software and junk on this hard-drive make it nearly impossible for windows to function on my Mac? Thanks for any input, it's much appreciated.
