My copy of vista absolutely will not boot if I connect a second hard drive on the ide cable(as a slave). It does the little "loading bar," but then the screen blanks out after that, and never boots(stops at crcdisk.sys). If I remove the slave drive it boots fine. The slave drive has a copy of linux installed on it, and I was hoping to just dual boot by switching the boot order instead of using a boot loader. The linux drive will boot by itself(if it's master), but kernel panics if I boot it with the vista drive connected. So to sum up, neither os works if both drives are connected at the same time, but either os can boot if it's the only drive(master). What can this mean? Also, I can't get my vista disc to boot if the slave drive is installed(with linux on it), but it works if the linux drive is disconnected. I can't see what could be the problem, both drives are separately installed copies of the os, so no bootloaders should be interfering, as I just want to select the drive in bios to boot. I also thought it might be related to my overclock, but I reset to default, and the situation is the same. The vista drive is a 80gb ide seagate(set cable select) and the linux drive is a 160gb western digital(set cable select), if that matters... Hopefully someone can help me...I've been messing with this for hours, and it's stressing me out.
