How to Boot from External Hard Drive Windows 11

In this section, we will walk through the steps to boot from an external hard drive on Windows 11. Following these instructions will change the boot order on your computer to prioritize the external drive.

Step 1: Plug in Your External Hard Drive

First, make sure your external hard drive is plugged into a USB port on your computer before you start.

Ensuring the drive is connected before you power up your computer or restart it is crucial. Otherwise, the system won’t detect the drive.

Step 2: Restart Your Computer

Next, restart your computer.

You can restart by clicking the Start button, selecting Power, and then choosing Restart. This will allow you to enter the BIOS settings during the boot process.

Step 3: Enter BIOS

During the initial boot screen, press the BIOS key (often F2, F12, Delete, or Esc) to enter BIOS settings.

The exact key varies by manufacturer; you might see a brief message on the screen telling you which key to press. Be quick, as you have a limited window to press it.

Step 4: Navigate to Boot Menu

Once in BIOS, use the arrow keys to navigate to the Boot menu.

The Boot menu lets you set the order of devices that your computer will try to boot from. Look for options labeled "Boot Order" or "Boot Priority."

Step 5: Set External Hard Drive as First Boot Device

Change the boot order so that your external hard drive is set as the first boot device.

You can usually change the order by selecting the device and using specific keys to move it up or down the list. Instructions are typically displayed at the bottom or side of the screen.

Step 6: Save Changes and Exit BIOS

Save your changes and exit the BIOS setup.

Typically, you can do this by pressing F10 or navigating to the "Save and Exit" option. Your computer will then restart.

After you complete these steps, your computer will attempt to boot from the external hard drive first. If the external drive is properly set up with a bootable operating system, it should start up from there.
