Hey, I'm having a problem on my desktop computer. At the moment I cannot boot into Windows XP or Windows Vista at all. I cannot boot into safe mode on either as well. With my Vista HDD, the safe mode driver load screen (pardon my description) will halt on "crcdisk.sys" With my Windows XP HDD, the safe mode driver load screen halts on "Mup.sys" The Xp HDD is an IDE drive and the Vista HDD is SATA. I've attempted to reinstall both Vista and XP but the Vista install stops at "Windows is loading files" and the XP install stops at "Setup is loading files." I've attempted booting up with both plugged in at the same time, one drive at a time, both plugged in while disabling one in the bios, but I really don't know where to go from here. Normally, only the SATA drive is connected as the IDE drive is my buddy's drive so I know it works. At this point I think it may have something to do with the mobo. Any kind of idea or suggestion would be greatly appreciated. ^_^ --Edit-- Edited info about mobo.
