Here's the deal. I have a company laptop (that I am typing on now). I can use it for personal stuff, but can't get too crazy installing things on it. I have a laptop that's a few years old but is acting up. I upgraded said laptop not too long ago with a 60GB 7200 RPM drive. I have pulled that drive and installed it in an external USB 2.0 chassis. I want to boot my company laptop off the USB drive and basically use it as a personal computer. The drive from my old laptop is bootable, has WinXP installed, and should be ready to go. But, I can't get this thing to even try and boot from it. I have the option in the BIOS to have it boot off a USB hard disk, and I also can hit F9 at POST and it'll let me select the boot device. I pick USB hard disk and get a black screen with a cursor in the top left. I know I gotta sort out device manager and get the correct drivers for the different hardware, but the thing should at least be able to boot, heck even try to boot. Anything simple I could be missing?
