Install Windows 7 from a bootable USB drive
There are times when it is more convenient to boot the Windows 7 installation from a USB drive rather than the DVD. For example, certain smaller form factor notebooks do not have DVD drives. The following steps allows one to create a bootable USB drive containing the Windows 7 installation content. This bootable USB drive can also be used to repair Windows in the event of software corruption. You will need a 4GB or greater USB drive and make sure the computer you wish to boot from the USB drive supports booting from USB.
