removing Widows 2000 setup from a windows 98 machine.

[ManoCooper]

I inherited a hard drive'that someone tried to install windows 2000 with out verifying the hardware requirements. I can boot to 98 fine but would like to give this PC to a friend. it does not bother me much but i do not relish getting calls every time he reboots the machine and he gets the BSOD when windows 2000 tries to install. I have tried booting with a 98 boot disk and typing sys C:. so I can remove the boot.ini etc but, it says invalid drive letter. When I try and switch to the C: I receive the same error. My question is where do I go from here?
Any help would be appreciated.

Do you have any files on the computer that you want to save?
