Now you can copy the other files (BIOS update or other DOS based programs) to USB disk by Windows explorer and start using.Ĭonnect the USB and restart the computer. Once the disk is formatted, it can boot your computer in FreeDOS OS. Once you have downloaded the Win98_bootdisk.iso file, browse the ISO while formatting USB disk as shown below. MS-DOS ISO can be downloaded here ( Win98_bootdisk.iso). Therefore, to create a simple bootable DOS USB disk in Windows 10 or 8.1, make sure to select ‘FreeDOS’.ģ) If you like to create MS-DOS bootable disk, select the MS-DOS version, but you need to have MS-DOS ISO file for that. I will test booting from rEFIt and update this answer when I have.Rufus comes with FreeDOS OS, so you do not need to download any DOS OS here. I know for a fact that Unetbootin works for creating bootable Windows install USB's (I've run them before on PC's). (boot to a rEFIt DVD by holding down the C key after you hear the chime of the startup) Having had trouble trying to install it to the Mac itself (without the DVD), I usually boot to the rEFIt DVD, and continue to boot to my choice of operating system. I recommend simply burning rEFIt to a CD/DVD to boot to the Windows 7 install USB.

It is useful for recognizing operating systems installed on your computer and devices connected to your computer (and their partitions). I use it myself to boot from an Ubuntu partition on my external hard drive that I use as a Time Machine on another partition. To boot from your USB drive, I recommend rEFIt. Click the "." button to browse for your image. (note that Unetbootin requires admin privileges) The following image demonstrates how to manually select the ISO image. Unetbootin allows you to create bootable USB drives from many Linux distributions and also ISO images.


Assuming that you have the ISO handy (if you don't, there's Digital River links here), download Unetbootin.
