Hello,I'm installing an existing boot hard drive in a different XP machine, and the boot process hangs right after the screen which counts down the seconds until booting. Screen displays a flashing bar as the cursor on an otherwise blank screen. Thoughts, experiences, solutions?? The "new" box has an Asus P4C800E deluxe mobo with 2Gb RAM. The previous boot drive was WinXP and the transplanted HDD is the same.
