How to Make a Bootable USB Disk and Install Windows 8, Windows 7, Windows XP

Ever faced a virus attack on your PC? Have an old laptop that refuses to boot up one fine day, throwing up errors such as bootmgr missing or NTLDR missing? Your best option in both these cases may be to reinstall Windows on your computer. When you first use your computer, you're prompted to create a DVD backup of your Windows install, but keeping a DVD safely and not losing it can be a bother. Being able to reinstall Windows using a USB you just keep nearby can be a big help, and to do this all you need to do first is create a bootable Windows USB drive. This is also very helpful if you bought a compact laptop - many smaller new devices don't have a DVD drive.

Remember you'll need a working Windows install (any version) to do this - if your computer won't boot, use a friend's to follow these steps.

Here's everything you need to know about the process.

How to Create a Bootable Windows 7 USB Drive

The first thing you need is a Windows ISO or an image file. This is a virtual copy of a Windows installation DVD and you can source this legally from Microsoft without a product key. Here are the links for various edition of Windows 7.

Windows 7 Ultimate (32 bit)

Windows 7 Ultimate (64 bit)

Windows 7 Professional (32-bit)

Windows 7 Professional (64-bit)

Windows 7 Home Premium (32-bit)

Windows 7 Home Premium (64-bit)

You'll still need a valid product key when you reinstall Windows so make sure you keep that safely.

Once you've downloaded the Windows 7 ISO file, follow these steps to burn it to a pen drive.

  1. Download the Windows USB/DVD tool from here and run it.

  2. Click Browse and select the downloaded Windows 7 ISO file.

  3. Click Next.

  4. The next page asks whether you want to save this file to a USB or a DVD. Click USB device.

  5. Connect a pen drive with at least 4GB space to your computer. Make sure you back up all data on the pen drive to your computer as it will be erased during this process.

  6. Select your pen drive from the drop down menu and click Begin copying.

  7. When this process is complete, you'll have a bootable Windows 7 USB ready.

Booting and installing Windows from USB Drive

Now you have a bootable pen drive ready, you can boot off this drive and install Windows. Installing Windows is quite straightforward, but the steps leading up to it may vary a little depending on the manufacturer of your computer. We've added a brief explanation below on how to do this.

When you're booting up the computer, on the very first screen, you'll see a text which says something like "Press Del to Enter BIOS". Press whatever key is listed - this is usually Delete, or one of F1, F2, F8, or F12 - when the computer is booting, to enter the BIOS. There, you need to find a menu like Advanced BIOS settings, and select USB as the primary boot device. Now, you need to save and exit BIOS - the key to do so will be listed on-screen, but it is usually F10. Plug in the USB, and when you reboot, you'll start the install process for Windows on your computer. Follow on screen instructions to install Windows 8, Windows 7, or Windows XP.
