My childrens' school has a machine with what looks to be a Debian installation with boot from the hard drive. They want to strip Linux from the box and install the other OS. Did the drop partition through fdisk. But on reboot, instead of getting a no operating system found message, LILO kicks in and then dies with a kernel panic. I'm presuming that LILO wrote to the master boot record. So how does one go about fully expunging Linux?
