Those of you with long memories might recall the days playing around Disk Operating System, but its known fact that DOS isn’t used widely anymore. The last thing I remember yet is that, I created a Bootable DOS pen drive for BIOS update. I would like to share my last memory with DOS which I performed to make a bootable pen drive.

Windows would not allow you to select the “Create an MS-DOS startup disk” option when formatting a USB drive, it will be grayed out. Instead lets us use Rufus. Rufus is faster, lightweight application includes FreeDOS.

Download Rufus here.

STEP 1) Connect your USB drive to the computer and select it in the Device box.

STEP 2) Ensure the “Create a bootable disk using” checkbox is enabled and ensure FreeDOS is selected.

STEP 3) Click the Start button. This will erase the contents of your USB drive! Back up any important files on the USB drive first.

I understand that, if you still on this post you have purpose of DOS based program to run, such as  BIOS update or low-level system application. Actually any of this applications you need to run files from DOS, you will need to copy them over to your USB drive and now boot into DOS by restarting your computer, make sure that the boot priority has been set to the USB drive in BIOS.

Once you are in DOS, you can run the program you copied by typing its name in DOS prompt or  follow any instructions provided in the manufacturer’s documentation to run the application.

I hope this post make you to remember the old days playing with DOS prompt. If you remember those days, please feel free to share your thoughts in comments and please do share.
