USB works the same way as CD, but we have to make the USB bootable first. This tutorial is for the windows 7,8 and later operating systems.

2. you will see command prompt screen, now type 'diskpart'
3. a new window will open that is administrator command prompt, on the new screen type 'list disk'
4. You will see a list of disk option, make sure to select your USB, now type 'select disk 1' if the disk 1 is USB
5. it will show that 'Disk 1 is now the selected disk'
6. after that type 'list partition'
7. it will show you a list of partitions, mostly it shows one option, now type, 'select partition 1' and press enter
8. Now type 'active'
9. and then type 'assign' and press enter
10. and type exit to exit the command prompt window.
