I have a 6 yr. old computer that has Windows 95 on it. I have a Win 98 cdr "for new pc's only" and was told I could format the hard drive to clear out the old op system (nothing else in there matters) and install Win 98 using this cdr. Since I don't know how to format the hard drive, I opted to borrow a friends win 98 update. The download seemed to go fine until the end. When it rebooted, you get the Win 98 Screen (w/o the icons), then it changes to my daughters "Select User Name" screen originally made in Win95, but now reads Win 98, then to a blue screen that reads "A fatal exception OD has occurred at 2157:000054CA. The current application will be terminated". I am not extremely knowledgable when trouble shooting pcs so the easiest step by step procedure to fix or to format the hd and reload new Win 98 disk procedure would be GREATLY appreciated.
