Booting from an external hard drive on Windows 11 can be a lifesaver when your internal drive has issues or you need to run a different operating system. By tweaking a few settings in the BIOS and making sure your external drive is properly prepped, you can easily boot up from your external drive. Let’s dive into the steps you’ll need to follow to accomplish this.
How to Boot from External Hard Drive Windows 11
In this section, we’ll walk through the process of booting your Windows 11 system from an external hard drive. This involves changing some settings in your BIOS/UEFI and making sure your external drive is set up correctly.
Step 1: Prepare Your External Hard Drive
Make sure your external hard drive is properly formatted and has a bootable operating system installed.
If you haven’t set up your external hard drive with a bootable OS, you’ll need to use a tool like Rufus or the Windows Media Creation Tool. These programs will help you create a bootable disk with your preferred OS.
Step 2: Connect Your External Hard Drive
Plug your external hard drive into a USB port on your computer.
Ensure the connection is stable and the drive is powered on if it has an external power source. This is crucial for the BIOS to recognize the drive.
Step 3: Restart Your Computer
Restart your computer to get into the BIOS/UEFI settings.
As your computer restarts, you’ll need to press a specific key (usually F2, F10, Del, or Esc) to enter the BIOS/UEFI. The exact key varies by manufacturer, so you might need to check your computer’s manual or look for a prompt during startup.
Step 4: Enter BIOS/UEFI Settings
Access the BIOS/UEFI settings menu.
Once in the BIOS/UEFI, navigate to the boot settings menu. This is where you can change the order of boot devices.
Step 5: Change Boot Order
Set your external hard drive as the primary boot device.
In the boot order menu, move your external hard drive to the top of the list. This tells your computer to check the external drive first for an operating system.
Step 6: Save and Exit BIOS/UEFI
Save your changes and exit the BIOS/UEFI settings.
Usually, there will be an option to "Save and Exit" (often the F10 key). Make sure you select this to apply your changes.
Once you’ve completed these steps, your computer should boot from the external hard drive. If all goes well, you’ll be running your operating system from the external drive.
