Recently one of the 25 computers I have in my classroom says something similiar to the following "Booting Error Insert System disk", preventing me to access the C: drive and starting Win 95. When I do reboot with a system disk in
drive A:, I'm still unable to access the C: drive; I get the
message "Invalid drive." Because of this I can do nothing to the C: drive. I've checked all the BIOS settings, and everything is identical to the 24 working computers. What can I do to get to my C: drive.
