I have 2 SATA HD with Windows XP SP3 installed on each of them. I would like to know if it is possible to connect both HD on the same computer. Then start one copy of WinXP and within this running XP, start the second XP at the same time. I saw a tutorial from TeraByte website using Image for Windows that I could do this by making an image of one HD and then run Virtual PC software. But I would like to do is starting both XP on the same machine without making any image file which will use some HD space.
