Step 2 : Boot To Recovery Disk

Next we need to boot to the USB drive we just created. With most machines you can press a button just before windows loads and this will bring up a one time boot menu. You will need to find out what this button is for your system (Usually F9 or F10)

If your machine does not have a one time boot option then you will need to go in to your systems BIOS and set the USB drive as the primary boot device. To get in to computer BIOS you usually have to press Del or ETC or F1, each computer is different.
