Aloha all. This may be OT, so maybe someone can point me in the right\ndirection...but I always get good replies here, and those people that don't\nlike OT...well, I'll givew them something to grump about...\nI'm using Vista Home Premium. I have a spare 250GB SATA drive, so I thought\nI'd install XP on that, then dual boot with my original Vista drive (AMD\nAthlon dual-core at 3 GHz, 4GB RAM, 64 bit Vista Home Premium...when it\nboots). The XP install seemed to go fine, in that the drive would boot up\nalone (with the Vista drive disabled). But when I plugged my main Vista\ndrive in, the system would not boot up at all. I would get a Drive Read\nerror.\nI don't get it. Both drives boot up fine by themselves, but when both are\nrunning, neither will boot. Do I need to set one drive's jumpers or\nsomething? I don't know SATA drive jumper settings, or if that's even the\nissue.\nCan someone give me at least a starting point?\nThank you.
