FreeDOS is a complete operating system. For new users, we recommend installing FreeDOS in a PC emulator or “virtual machine.” If you install FreeDOS directly on a computer, without using a PC emulator, you may overwrite the operating system you have now (for example, Windows.) Please be careful.
We recommend the CDROM installer for most users. The “standard” CDROM image should work on most computers and PC emulators. Older computers may need the “legacy” CDROM image instead.
