Press F8 once after the PC has detected the IDE devices (hard drives and cd roms, while the tables are loading displaying all the devices and \"VERIFYING DMI POOL....\"), then select SAFE MODE or PROMPT ONLY... alternatively pressing F5 will take you straight into safe mode.
If you are still unable, open a command prompt in XP (hold windows key and press R, type CMD and hit enter) then put a BLANK floppy into your floppy drive and type:
format a: /s
[press enter]
LEAVE THE FLOPPY IN THE DRIVE and reboot your PC... then follow everyone else\'s direction on overwriting the ntoskrnl.exe in DOS...
If you still can\'t do it, Get a win98 cd and pop it in your cd drive, reboot, format your drive and install 98... you dont deserve XP.. LOL
