The general idea is too install XP from my desktop comp onto my laptop HDD which is in an external USB enclosure. My laptop is a Toshiba Satellite P35-S609. It's a P4 3.2ghz with hyperthreading. The desktop is an AMD 3700+. My reason for wanting to install the OS onto the laptop HDD outside of the laptop it is intended for is b/c I believe I have exhausted all other options of getting this computer to load an OS. I have tried several versions of UBCD and BartPE but I am under the impression that the computer simply won't boot from a USB. Yes, I changed the boot order to "removable devices" in bios. I have also tried booting from Win XP CD and UBCD and several other boot discs but I am under the impression that the bios simply isn't recognizing the dvd drive. It powers up when I push the eject button but does nothing when I try to boot from it. (Once again I changed the boot order in bios to boot from DVD). So my only other option for booting is to boot from a network and well I really don't want to start tackling that. The history of the situation is that I used a program called drivercleaner pro, which I have used with no problems before, and I think it erased chipset drivers. I was getting a BSOD immediately when windows began to load. So I saved the files from the laptop and then reformated it preparing for a reinstall. But now I am unable to boot from DVD as I have done in the past on this very same computer. My other option of resetting the bios is, to my knowledge, work for a tech since the CMOS battery is soldered to the MB and there are no jumpers to clear cmos. So I read a little on the sysprep and HAL but it didn't seem to address what I was attempting. So I'm at a loss and any help would be appreciated. I realize I didn't leave my sys specs, kind of hard as I'm at work at the moment but I can provide further information shortly.
