Chances are you’ll need to install Windows 7 from a USB drive if you have a tablet, a small laptop, or a netbook. Many of these devices come with an optical drive by default.
Install Windows 7 from a USB (flash drive, external HD)
You will need to migrate the Windows 7 installation files to a flash drive (or USB storage) and then boot from that flash drive to begin the Windows 7 installation process. However, simply copying the files from your Windows 7 DVD to a flash drive will not work. You will need to prepare the USB device specifically and then properly copy the Windows 7 installation files to it before it will work as you expect.
