Changing the boot order in Windows 10 allows you to select which device your computer starts from, such as a USB drive, DVD, or internal hard drive. This is essential when installing a new operating system, troubleshooting boot issues, or running diagnostic tools. Before you begin, ensure you have the necessary permissions—typically administrator rights—and that the device you want to boot from is connected and prepared. This guide walks you through the entire process step-by-step, so you can confidently modify your boot sequence and troubleshoot any related issues.
What You’ll Need
- Administrator access to your Windows 10 PC
- The device you want to boot from (USB, DVD, etc.)
- Optional: a backup of important data in case anything goes wrong
Step-by-Step
- Start by opening the Settings menu. Click on the Start button and select the gear icon to open Settings, or press Windows key + I on your keyboard.
- Navigate to the ‘Update & Security’ section within Settings.
- From the sidebar, click on ‘Recovery.’ Under the ‘Advanced startup’ section, click ‘Restart now.’ Your PC will reboot into the Windows Recovery Environment (WinRE).
- Once your PC restarts, you’ll see a blue screen with options. Select ‘Troubleshoot.’
- Next, click on ‘Advanced options,’ then choose ‘UEFI Firmware Settings.’ If you don’t see this option, your PC might be using legacy BIOS instead of UEFI, and the process differs slightly.
- Click ‘Restart’ to reboot into the UEFI firmware settings. Your computer will now open the BIOS/UEFI setup utility.
- Within the BIOS/UEFI interface, locate the ‘Boot’ tab or menu. The exact location varies depending on your motherboard manufacturer.
- Find the ‘Boot Order’ or ‘Boot Priority’ list. Use the arrow keys or the on-screen instructions to select your desired boot device (USB, DVD, or internal drive).
- Adjust the order by moving your preferred device to the top of the list. This is often done by pressing specific keys (such as + or -) or using designated menu options.
- Save your changes. Usually, this involves pressing F10 or selecting the ‘Save and Exit’ option. Confirm if prompted.
- Your PC will restart, now attempting to boot from the device you prioritized. If successful, the device’s setup or contents will load instead of Windows.
Common Mistakes
- Not saving BIOS/UEFI changes before exiting—this will prevent the new boot order from applying.
- Confusing UEFI with legacy BIOS settings; ensure you’re accessing the correct firmware interface.
- Attempting to change boot order from within Windows without using the firmware settings—this isn’t possible; the change must be made in BIOS/UEFI.
- Forgetting to prepare the boot device properly—ensure your USB or DVD is correctly formatted or configured as bootable.
- Misidentifying devices in the boot menu—double-check device labels to avoid selecting the wrong one.
Tips
- Consult your PC or motherboard manual for specific instructions if the BIOS/UEFI interface looks different.
- If your PC uses Secure Boot, you might need to disable it temporarily to boot from certain devices like Linux or other OS installers.
- Use a USB drive formatted as bootable with tools like Rufus for installing or troubleshooting OS issues.
- Keep your firmware updated to ensure compatibility and access to the latest features.
- Note that some laptops may have a dedicated key (like F12, F11, or Esc) to access boot options directly during startup, bypassing the BIOS menu.
Troubleshooting
If changing the boot order does not work as expected, consider the following steps:
- Ensure the device is bootable: Check that your USB or DVD is properly created as a bootable device. Use tools like Rufus or the Windows Media Creation Tool to prepare your media.
- Disable Secure Boot: Some systems restrict booting from external devices when Secure Boot is enabled. Access BIOS/UEFI and disable it temporarily, then try again.
- Update BIOS/UEFI firmware: Outdated firmware can cause issues with boot order changes. Visit your PC or motherboard manufacturer’s website for updates.
- Reset BIOS/UEFI to default settings: Sometimes, custom configurations interfere with boot options. Resetting to defaults can resolve this.
- Check boot device connections: Ensure that your USB or DVD drive is properly connected and recognized by the BIOS/UEFI.
- Use manufacturer-specific tools: Some systems have dedicated utilities or keys for managing boot options; consult your device’s manual.
If all else fails, contacting technical support or a professional technician might be necessary to resolve hardware or firmware issues.
Frequently Asked Questions
1. Can I change the boot order without restarting my PC?
No, boot order adjustments are made within the BIOS/UEFI firmware, which requires a restart to access.
2. What is the difference between UEFI and legacy BIOS?
UEFI is a modern firmware interface offering faster boot times and security features, while legacy BIOS is older and less flexible. The process to change boot order varies slightly between them.
3. Do I need to disable Secure Boot to boot from a USB drive?
Not always, but Secure Boot can prevent booting from some external devices. Disabling Secure Boot in BIOS/UEFI may be necessary for certain bootable media.
4. How do I know if my PC uses UEFI or BIOS?
You can check in Windows by typing ‘System Information’ in the Start menu and looking for ‘BIOS Mode.’ UEFI will be listed if applicable.
5. What should I do if my PC doesn’t recognize my boot device?
Ensure the device is properly formatted and bootable, connected correctly, and compatible with your system. Updating firmware and checking BIOS settings can also help.
6. Is changing the boot order safe?
Yes, as long as you know what you’re doing. Incorrect settings won’t harm your hardware but could prevent your PC from booting properly. Always proceed carefully and backup important data.
