You can do this by pressing and holding the computer's "Power" button, or you can click Start, click the Power icon, and click Shut Down. Make sure your computer is completely shut down before proceeding. Press your computer's "Power" button to do so. Your computer will begin turning back on. As soon as your computer begins to boot up, begin pressing rapidly the key your computer uses to open the BIOS. You can stop pressing the key once the BIOS page opens. If your computer restarts before you have a chance to press the BIOS key, you'll need to turn back off and then on your computer and try again. Using the left and right arrow keys, scroll through the BIOS tabs until you find a list of boot items.  You may have to select Boot Order (or similar) and press ↵ Enter to open the menu. Each computer's BIOS will be different, so consult your computer's online documentation if you can't find the boot order menu. Use the arrow keys to scroll down until you've selected the USB flash drive's name. In most cases, you'll press the + key until the flash drive's name is at the top; if this doesn't work, consult the key legend at the bottom (or side) of the BIOS screen for instructions. Press the "Save and Exit" key as specified by the key legend. Doing so will save your changes to the BIOS and then exit the BIOS screen. You may have to confirm your choice by pressing another key before you can proceed. If your computer finishes starting into Windows, restart your computer before proceeding. This will open the Windows 7 installation page, from which point you can begin installing Windows 7.
