Thats the ntloader thats missing. wont load without it.

i doubt it will work in safe mode or anything either, but its worth a punt. f8 on boot up.

or do you have a floppy drive? is there a disk in there? it could be trying to boot from that device first. if theres a disk in the drive, take it out and reboot.

if not, it could be a faulty hard drive or just a corrupt OS.
