“Do you have an old ME floppy?
FDISK!!”
Don’t think so but I no longer have a compute with a floppy drive.
I do have my old copy of ME on CD.
It’ll probably boot into a DOS type mode and you should then be able to run FDISK.
Assuming, of course, that you have already saved what you want/can off of the hard drive...
Good luck! All my machines are configured for dual boot at least, some even have Linux partitions on them.
