Two ways.
1. You can do "lilo -U", which will uninstall LILO and reinstate the original boot MBR, *if* you installed LILO on the MBR in the first place.
2. You can boot off a Windows 98 boot floppy or similar and issue "FDISK /MBR".
3. Boot off a Windows 2000 CD, go to the Recovery Console, and issue "FIXBOOT".
