A bootable USB Drive is a alternative way to install operating systems on netbooks without optical drives, or carrying around a Live OS with you at all times. It especially makes sense if you’re installing software on a machine that otherwise has no need for an optical drive:
Open “CMD”
C:\> diskpart
DISKPART> list disk
Select the USB device from the list and substitute the disk number below
when necessary
DISKPART> select disk 1
DISKPART> clean
DISKPART> create partition primary
DISKPART> select partition 1
DISKPART> active
DISKPART> format fs=fat32
DISKPART> assign
DISKPART> exit
xcopy Y:\*.* /s/e/f Z:\
