Surprisingly, it can run on brand-new CPUs if you have a USB floppy drive, but the ISO method is much smoother for virtual machines.

DOSBox is an emulator specifically designed to run old DOS games and software. It abstracts modern hardware, making it incredibly easy to install Windows 3.1 without worrying about making a bootable ISO.

You cannot install Windows 3.1 directly onto modern computer hardware (such as a Windows 11 PC with an NVMe SSD and a UEFI BIOS). Instead, you must use emulation or virtualization. Method 1: DOSBox (The Easiest Route)
