Hello,
Thank you for posting in Microsoft Community.
I appreciate your inquiry regarding booting from a USB drive on your Surface device. Let’s address this step by step.
- Legacy Booting on Surface:
- While Surface devices primarily use UEFI (Unified Extensible Firmware Interface), you can still boot from a USB drive using legacy (BIOS) mode.
- Follow these instructions to boot from a USB device on your Surface:
- Shut down your Surface.
- Insert the bootable USB drive into the USB port on your Surface.
- Press and hold the volume-down button on your Surface.
- While holding the volume-down button, press and release the power button.
- You’ll see the Microsoft or Surface logo on your screen.
- Continue holding the volume-down button until you see spinning dots beneath the logo.
- Follow the on-screen instructions to boot from your USB drive.
- This process allows you to start your Surface using Windows or another operating system from your USB device.
- UEFI Booting and Changing Firmware Settings:
- If you prefer UEFI booting, you can configure your Surface to start from a USB drive in UEFI mode.
- Here’s how:
- Shut down your Surface.
- After it turns off, press and hold the volume-up button.
- While holding the volume-up button, press and release the power button.
- Continue holding the volume-up button until you see the Surface UEFI screen.
- Follow specific instructions for your Surface model to proceed.
- Change the boot order in the UEFI settings to prioritize the USB drive.
- Additional Tips:
- Ensure that no other USB devices (such as mice, keyboards, or storage drives) are connected during boot.
- If you encounter any issues, you can also try booting through Windows:
- Insert the USB drive and go to Start > Settings > System > Recovery.
- Under Advanced startup, select Restart Now.
- On the Choose an option screen, select Use a device > USB Storage.
- Creating a Bootable USB Drive:
- If you haven’t already, create a bootable USB drive with the desired operating system.
- For Surface recovery, you can also create a USB recovery drive.
Remember that booting from a USB device won’t refresh or reset your Surface—it simply allows you to choose an alternative startup option.
