im helping out a friend with their comp. they want to upgrade from windows 95 to 98se. we put in the 98 se disk, and theres an error that pops up saying to run a scan dish to be able to locate the drives but that dosent seem to work. is there a way to just completely reformate the hd and install the new windows. nothing needs to be saved so any suggestions on the easiest way to do this would be much appriciated.
