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.

What's changed from FreeDOS 1.1
How to install FreeDOS 1.2
The FreeDOS 1.2 distribution is available in multiple formats:
CDROM “standard” installer
CDROM “legacy” installer
Boot floppy (see notes below)
USB “Full” installer
USB “Lite” installer
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.
If your computer cannot boot from CDROM, use the boot floppy. Write this image to a floppy with Rawrite or dd, boot it, then insert the install CDROM when the install program starts up.
If your computer doesn't have a CDROM drive, use the USB fob drive installer. Write this to a USB fob drive and boot it to start the install. The “Full” and “Lite” versions install the same FreeDOS, but the “Lite” installer does not contain some extra bonus software packages.
How much space do you need? At minimum, you need at least 10MB to install just Base, without source code. Or at least 81MB to install everything, including source code.
