I have an old Dell 486 with Windows 95(b I think) installed. It still has the options "boot to previous version of DOS" (my old version of DOS is 6.0) in the boot menu, which is activated every startup cycle thanks to a TweakUI setting, and my question is: Can I install Windows 3.1 on the "old version..." boot and use it like I would any other normal installation of Windows 3.1?

I'm thinking that I probably can. I have two hard disks with FAT16 (or maybe earlier, I just know it's not FAT32). Also the machine used to have Windows 3.1 before a few unfortunate file deletions sent it packing; and a CD-ROM for windows 95 meant I wouldn't bother re-installing 3.1 (also the disks I had didn't work at the time, they do now because it was looking for a certain driver that was corrupt, and I changed my hardware settings to a compatible brand with a non-corrupt driver on the disk)

The old version of DOS boots just fine, and I can use it with no problem. I'm just not sure if Windows 3.1 (installed in a different directory, of course) would upset my current version of Windows.
