If you are running windows 98:

Boot into safe mode.

Run regedit


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS

Look for the string "NoIde"
Make sure that you find this exact string it will be a string value in the right hand pane. Delete the NoIde entry. Reboot your computer.

This only works if you have Win95 or Win98.

Just saw you said xp disk. Hopefully this will help someone else then.

If it is XP can you boot up in safe mode, remove the ide controller, then reboot?
