Step 1: Boot From the Windows 7 DVD or USB Device
To begin the Windows 7 clean install process, you’ll need to boot from the Windows 7 USB or DVD if you’re using a Windows 7 DVD, or boot from a USB device if your Windows 7 installation files are located on a flash drive or other external USB drive.
Tip: See my Windows Installation FAQ if you you have Windows 7 as an ISO image that you need on a flash drive or disc, or a Windows 7 DVD you need on a flash drive.
Restart your computer with the Windows 7 DVD in your optical drive, or with the properly configured Windows 7 USB flash drive plugged in.
Watch for a Press any key to boot from CD or DVD… message similar to the one shown in the screenshot above. If you’re booting from a flash drive, the message may be phrased differently, like Press any key to boot from external device….
Press a key to force the computer to boot from the Windows 7 DVD or USB storage device. If you do not press a key, your computer will attempt to boot to the next device in the boot order, which is probably your hard drive. If this happens, chances are your current operating system will boot.
