Nowadays floppies and their drives are rarely found. So creating a bootable floppy is not worthy. With this hack you can create a bootable pen drive having MS DOS installed in it.
USE: The bootable pen drive can be used to boot into DOS and perform the commands without booting into windows. You can perform major operations like formatting your system drive ( C:\).
Step 1: Download the software named "windows enabler" from here.
Step 2: Install the software.
Step 3: On the task bar click on the enabler icon formed so that it displays "ON".
Step 4: Now go to "my computer" and right click your pen drive.
Step 5: Click on the " format" option in the context menu.
Step 6: Select the option "create an MS-DOS startup disk" and click on "start".
Your pen drive is now ready to boot. Change the boot option in your BIOS setting to boot from the pen drive.
