Making USB Bootable Win7

First need to sure you got your USB data backed up, since we need to clean up.

Run in Windows command prompt.

c:\ diskpart
DISKPART> list disk
DISKPART> select disk <your disk number>
DISKPART> create partition primary
DISKPART> select partition 1
DISKPART> active
DISKPART> format fs=fat32

Wait the slow formatting and then copy and paste from the iso to the USB drive
