I'm upgrading a few old IBM 300GL desktops to Windows 98 for someone and have run into a bit of a problem with one of them. Before I did anything the system was running Windows 95 Plus just fine. I inserted the Windows 98 (for PCs without Windows) install CD inside of Win95. I think it's '98 first edition but if it's second edition I probably would have seen that on the case.
So I ran setup from Explorer. I continued through the install process until it completed. When it did, the desktop, menus, and other things looked normal, and the start menu said Windows 98. All is well, right?
But ironically, when I started up the computer the next day the BIOS gave me the message "Missing operating system". I don't know what could've corrupted the filesystem, as far as I know I did everything properly. Maybe it has something to do with the MBR? I tried booting from the Win98 startup floppy. I chose the CD-ROM support option, and entered the DOS prompt running from A:. But what do I do from here? Can I use the startup floppy to re-install/repair Windows?
I'm afraid to do this with the other computers until I find out why the system won't boot. This is my first time going this in-depth with older OS's, so help would be much appreciated.
boot off the floppy without cdrom option, do a scandisk on c:drive. also do a chkdsk c:/f. if can do it, do a fresh install of 98 instead of upgrade from 95.
