Uninstall QNX boot loader


I’m having trouble removing the QNX boot loader from my hard drive. I have
Windows 2000 Pro on the first partition. I had QNX on the second partition,
but I decided to remove it. When I booted into the Win2K Emergency Recovery
Console to do a “fixboot” and “fixmbr”, I was no longer able to boot into
Windows. However, I tried doing a minimal installation of Red Hat 8.0 on
the second partition and installed GRUB. When I boot Windows from that, I
get the Windows 2000 boot menu. Can anyone help me completely remove the
QNX boot loader from my hard drive? Much thanks.
