3.1 won't install on current hardware, in fact you'd need a pretty damn old computer. Keep in mind that you will also need to install DOS.

So if your old computer is from that time range, yes. Win 3.1 was around from early 90s to around 2001. It depends on how old your old computer is. And it has NO networking capability, and little use without all the updaqtes that were availalble when it was last supported. 3.1 will not run 0n current hardware or drives. Of course you can if it is about 20 years old. Best thing to do if you wish to use legacy operating systems is run a virtual machine using something like virtualbox, which is a free download. With a Virtual Machine, you can get better results than with a real hardware, as it creates automatically a hardware profile supported by MS DOS&Windows 3.1/3.11 and it has even its drivers already. Anyway, it will be better if you use VirtualBox instead.

This is how it can be done, but you'll face enough problems with your hardware, as there aren't drivers support for 16bit Windows and once installed you can't do much with it, unless you have an very old application. First you'll need to have Drivers for CD/DVD ROM, that after install DOS to load that, or you'll not be able to install Windows 3.1/3.11 by CD ROM unless you have a Floppy Drive and some Diskettes to copy windows installation and install from it from those. By creating a FAT 2GB disk Partition, you can install MS DOS 6.22 and after install Windows 3.1/3.11. That depends on Hardware and today's hardware are not supported by MS DOS 6.22 that is needed to run Windows 3.1 or Windows 3.11 Workgroup. Windows 3.1 won't even run on most modern computers, because MS-DOS 32 was removed in Windows Vista and newer versions of windows. Modern computers do not operate in DOS 16 bit, or DOS 32-bit Mode, which is required by 3.1. But, if the PC is less than 14 years old, you are beat. If the PC originally ran Windows 3.1, it will work, but Device Drivers are nearly impossible to find.
