There isnt a such thing as a Windows 3.1 boot disk, per say. Windows 3.1 cant boot itself anyway, it has no kernel. It boots off dos, so you would really need a dos boot disk. You could use dos disk one as mountain said, but you would be better off using an optimized MS-DOS boot disk (like this one: http://roy.hp2.jp/gpc/mirror.mw16/M... , for dos 7.1, there are plenty of diff versions of dos boot disks on the web with diff features and drivers). However, if you want to boot the Windows 3.1 Gui off a floppy, that is ALSO possible, using Mini Windows boot disks. Here is a link to try out a Mini Windows 3.1 boot disk with cd rom support on top of dos 7.1 : http://roy.hp2.jp/gpc/mirror.mw16/P... . Matthew R.
