. Even though most modern operating systems give you the option of keeping your files when installing the operating system, backing up your files is a safety precaution that you shouldn't skip. Your USB flash drive or burned DVD should be attached to/inserted into your computer. Click Start in the bottom-left corner of the screen, then click the arrow to the right of Shut down and click Restart. You'll need to do this as soon as your computer begins to restart. This key is usually the Esc, Delete, or F2 key, though your computer's BIOS key may be different. Don't stop pressing the key until the BIOS is open.  If you miss the BIOS activation window, you'll need to restart your computer and try again. For a brief moment, you can usually see the key that you need to use listed at the bottom of the screen in a "Press X to enter startup" message. You can check your computer's manual or product page online to confirm the BIOS key. Each computer's BIOS varies slightly, but you'll usually see a "Boot Order" or "Boot Options" tab that you can navigate to using the arrow keys.  On some BIOS layouts, you'll find the "Boot Order" options in the Advanced Options tab. Some BIOS layouts have the "Boot Order" section right on the initial page. Using the arrow keys, select either Removable Storage (or something similarly descriptive of a flash drive) or CD Drive (or something similar). This will depend on whether you used a flash drive or a DVD to create your installation tool. Usually, you'll press the + key while the tool's option is selected to do this. With your installation option at the top of the "Boot Order" list, your computer will be able to find and recognize the Windows 7 installation file. There's normally a key legend that tells you which keys perform which actions in the lower-right side of the BIOS page. Press your BIOS' "Save and Exit" key (check the key legend), then wait for the BIOS to close. You may have to confirm this decision by selecting YES and pressing a key.
