How to Make a Bootable USB With FreeDOS

by John Mitchell

FreeDOS is a free, open-source DOS operating system that works on IBM personal computers. The system is built from many software packages that have been contributed to the project code. You can create a bootable USB drive that loads FreeDOS on startup. You will need to download a copy of UNetbootin to transfer the operating system to the USB drive.

Visit the UNetbootin software page on Sound Forge (see Resources). Download the single-file program and run it by double clicking on "unetbootin-windows-latest.exe."

Click the "Distribution" drop-down menu, then choose "FreeDOS." Select the highest version. Keep the default settings as is.

Insert the USB drive into the computer.

Select the USB drive under the "Drive" field, then click the "OK" button.

Wait for the program to go through a four-step procedure. It must download, extract and copy files, then install the bootloader onto the drive.

Reboot the computer with the USB drive in the port. FreeDOS should automatically start up.


  • check At the DOS prompt, type "dir" to view the USB drive contents.
  • check Type "C:" or the drive letter to switch hard drives.
  • check If you're a software developer or programmer, you can contribute code and debugging resources to the FreeDOS Project.
