Format from USB stick

[Hairboi]

I need step-by-step guide on how to format windows from a USB stick if anyone can help please

 

[SiriusB]

Just to be clear, by "format Windows" do you mean format your HDD? i.e., erase all data from your hard drives? If yes: http://www.killdisk.com/

If no, please be clearer.

Do you mean wipe the hard drive or reinstall Windows?

Just do a google of what you want to achieve..
