If you would like to install a new version of Windows or you would like to install another operating system on your Windows 7 PC, you will likely need to boot your PC either from a USB drive or a CD drive. In this guide, we’re going to talk about how you can boot your Windows 7 PC from a USB pen drive.

If you have a bootable USB pen drive, then you are good to go to install a new operating system on your PC as a bootable USB works just as fine as an actual bootable CD or DVD. All you have to do is plug in your USB drive to your PC and then instruct your PC so that it boots up from the USB drive and not from the hard drive which it usually does.

If you have never booted your PC from a USB drive, you might think it is hard to do that. In fact, it is just as easy as normally booting up your PC. You just have to press a key while your PC is booting up and you will be able to boot it up from your USB drive.

Part 1: How to Create a Windows 7 Bootable USB

Before you get started, you’ll need to have a Windows 7 bootable USB drive. Below we list 2 ways for you to make a Windows 7 bootable USB.

Part 2: How to Boot Windows 7 from a USB Drive

Now follow steps below to boot your Windows 7 PC from USB.

Plug in your bootable USB drive to one of the USB ports on your PC. If your USB is 3.0, then make sure to plug it into a USB 3.0 port on your PC for faster data transfer speeds.
Then, boot up your PC as you would normally do. When you see the BIOS screen, you will see a key that you need to press to select a boot device. Usually, it’s the F12 key, but if your screen shows another key, press it and you will be able to select a boot device.
