Ever wondered how your computer knows where to start when you press that power button? It’s all about the boot order, a hidden setting that tells your Windows 10 PC where to look first for its operating system. Maybe you are trying to install a new version of Windows, run a special repair tool from a USB stick, or even just boot into an older operating system. Whatever your reason, changing the boot order is a fundamental skill that puts you in control. It involves restarting your computer, quickly pressing a specific key to enter the BIOS or UEFI setup, locating the “Boot Options” menu, and then rearranging the device list. You will then save your changes and exit, letting your computer restart with the new instructions. It is a straightforward process once you know the steps.
How to Change Boot Order Windows 10 Tutorial
This section will walk you through the precise steps to adjust your computer’s boot order. By following these instructions carefully, you will be able to tell your Windows 10 PC exactly which device, like a hard drive or a USB stick, it should try to start from first.
Step 1: Restart your computer and access BIOS or UEFI.
Restart your computer and watch for a quick message on the screen, usually “Press DEL to enter Setup” or “Press F2 for BIOS.” This is your golden ticket to the computer’s basic settings, often called BIOS or UEFI, which is like the computer’s brain before Windows even wakes up. The key you need to press can vary by computer brand, so it might take a few tries. Common keys include Delete, F2, F10, or F12.
Step 2: Navigate the BIOS or UEFI menu.
Once you are in the BIOS or UEFI, you will see a screen that might look a bit old-fashioned or very sleek, depending on your computer’s age. This menu is usually controlled by your arrow keys on the keyboard, not your mouse. Look for tabs or sections labeled “Boot,” “Boot Options,” “Startup,” or something similar. These are the areas where you will find the settings we need to change.
Step 3: Locate the boot order settings.
Within the “Boot” section, you will usually find a list of devices. This list shows the order in which your computer currently tries to start up. For example, it might list your primary hard drive first, then a CD drive, and then a USB drive. You are looking for a section that specifically lets you rearrange these devices, often titled “Boot Device Priority” or “Boot Order.”
Step 4: Change the boot order.
Now comes the exciting part: changing the order. Use your arrow keys to highlight the device you want to boot from first, such as your USB drive, then use the indicated keys to move it up the list. The on-screen instructions usually tell you which keys to use for moving items, often F5/F6 or +/-. Make sure the device you want to start from is at the very top of the list.
Step 5: Save your changes and exit.
Once you have set the boot order exactly as you want it, you need to save those changes. Look for an option like “Save and Exit,” “Exit Saving Changes,” or “F10 Save and Exit.” Press the key or navigate to the option, and then confirm your choice. Your computer will then restart, keeping your new boot order settings in mind.
After you complete these steps, your computer will reboot and, this time, follow the new instructions you gave it. If you set it to boot from a USB drive, for instance, it will try to start from that USB drive first.
Tips for Changing Boot Order Windows 10
Here are some helpful tips to make your experience smoother when adjusting your computer’s boot sequence.
- Always double-check the specific key for your computer’s BIOS or UEFI. It can vary widely between brands like Dell, HP, Lenovo, or custom-built PCs, so a quick search for your exact model might save you time.
- Understand that UEFI is the newer, more advanced version of BIOS, offering features like Secure Boot and a graphical interface, but the core process of changing boot order is quite similar in both.
- Be careful not to change other settings in the BIOS or UEFI menu unless you know exactly what they do, as some settings can affect your computer’s performance or stability.
- Know why you are changing the boot order; for example, if you are installing Windows from a USB drive, ensure the drive is plugged in and contains the installation files before you start.
- Look for a “Boot Override” or “Boot Menu” option, often accessed by a different function key (like F12). This allows you to choose a one-time boot device without permanently changing the boot order, which is handy for quick tasks.
- Always remember to save your changes before exiting the BIOS or UEFI setup, otherwise, your adjustments will not take effect.
Frequently Asked Questions
What is boot order and why is it important?
The boot order is simply the sequence in which your computer checks different storage devices, such as your hard drive, DVD drive, or a USB stick, to start the operating system. It is important because it tells your computer where to find Windows or any other operating system. If you want to start from something other than your main hard drive, you need to change this order.
Why would I need to change my Windows 10 boot order?
There are several common reasons why you might want to change it. The most common is when you are installing a new operating system, such as Windows 10, from a USB flash drive or a DVD. You might also change it to run diagnostic tools from a bootable disc, recover data, or troubleshoot problems with your current Windows installation.
What if I cannot get into the BIOS or UEFI setup?
If you are having trouble getting into the BIOS or UEFI, you might be pressing the wrong key, or not pressing it quickly enough. Try restarting your computer multiple times and rapidly tapping the common keys (Delete, F2, F10, F12) right as it starts up. If that fails, consult your computer’s manual or search online for “how to enter BIOS” for your specific model.
Will changing the boot order delete my files or damage my computer?
No, absolutely not. Changing the boot order simply tells your computer where to look for an operating system; it does not touch any of your files or settings on your hard drive. It is a completely safe operation for your data. You are just changing a preference, not altering the data itself.
Can I change the boot order from within Windows 10 itself?
You cannot directly change the permanent boot order from within the regular Windows 10 desktop environment. The boot order setting is part of the computer’s firmware, either BIOS or UEFI, which loads before Windows even starts. However, Windows 10 offers an advanced startup option to boot from a specific device once, similar to a “boot override” menu.
Summary
- Restart computer, enter BIOS/UEFI.
- Navigate to boot options.
- Locate boot order settings.
- Adjust device priority.
- Save changes and exit.
