Understanding how to change boot order in BIOS is crucial for anyone looking to optimize their computer’s performance. The boot order determines the sequence of devices that are checked for an operating system when the computer starts up. Adjusting this order can help you quickly access a recovery disk, install a new OS, or run diagnostics. In this article, we’ll guide you through the process and provide insights into why changing the boot order might be necessary for your computing needs.

Understanding BIOS and Boot Order
Before diving into the step-by-step process, it’s essential to understand what BIOS is and why boot order matters.
What is BIOS?
BIOS stands for Basic Input/Output System. It is firmware that is embedded on your computer’s motherboard. When you power on your computer, the BIOS initializes hardware components and performs a Power-On Self Test (POST) to ensure everything is functioning correctly. Once these checks are completed, the BIOS looks for an operating system to load based on the defined boot order.
Why Change Boot Order?
The most common reasons for adjusting the boot order include:
- Installing a New Operating System: If you’re installing Windows, Linux, or another OS from a USB drive or DVD, you may need to set that device as the primary boot option.
- Running Diagnostics: Sometimes, accessing a diagnostic tool or recovery environment requires altering the boot sequence.
- Troubleshooting Boot Issues: If your OS fails to start, you might want to boot from a live USB or recovery media.
Changing the boot order effectively allows you to manage how your system starts up, providing flexibility in how you troubleshoot or upgrade your system.
Common Devices in Boot Order
Typically, you can set the following devices in the boot order:
- Hard Drive
- Solid State Drive (SSD)
- USB Drive
- CD/DVD Drive
- Network Boot (PXE)
Being familiar with these options can make it easier to determine which device you should prioritize based on your current objectives.
Accessing BIOS Settings
Now that you have a solid understanding of BIOS and boot order, let’s explore how to access the BIOS settings.
How to Enter BIOS Setup
To change the boot order, you first need to enter the BIOS setup. This process varies slightly depending on your manufacturer but generally involves pressing a key during startup.
Most commonly used keys include:
- F2: Often used by Dell, Lenovo, and Acer.
- Delete: Commonly seen on ASUS and MSI motherboards.
- Esc: Frequently used by HP computers.
You must press this key rapidly right after powering on your machine. If done correctly, you’ll gain access to a screen filled with several options, including boot settings.
Once inside the BIOS menu, navigating can feel daunting due to its technical interface.
- Using Arrow Keys: Most BIOS menus are navigated using the arrow keys on your keyboard. Familiarize yourself with the layout, focusing on sections related to boot options.
- Enter Key: This key is typically used to select or enter a highlighted option.
- Esc Key: Use this key to backtrack or exit out of menus without making changes.
By understanding these basic navigation tools, you can seamlessly move around the BIOS.
Understanding the Layout of BIOS Settings
Every manufacturer has its unique BIOS layout, but you can generally expect to see sections such as:
- Main: Overview of system information
- Security: Password options and security settings
- Boot: Where you will adjust boot orders
- Exit: Option to save changes or exit without saving
Recognizing these sections can facilitate an efficient modification of the boot order.
Changing the Boot Order
Now, let’s delve into the actual process of changing the boot order.
Finding Boot Options in BIOS
Once you’re in the BIOS setup, locating the boot options is your next task.
- Boot Tab: Most systems feature a dedicated “Boot” tab. Navigate here to find all available boot devices.
- Boot Priority List: Within this section, you’ll see a list of devices arranged in the current boot priority order.
This visual representation makes it easy to understand how your computer is currently configured to initiate the startup process.
Modifying the Boot Order
With the boot options identified, it’s time to make the change.
- Selecting the Device: Highlight the device you want to move using the arrow keys.
- Changing Priority: Usually, the + or – keys can be employed to alter the order. Alternatively, some BIOS setups allow you to use a designated key to move the selected device to the top or bottom of the list.
Understanding this process is crucial because the first device in the boot order will always be prioritized during startup.
Saving Changes and Exiting
After you’ve made your desired adjustments, don’t forget to save your changes!
- Save and Exit: Look for an option at the bottom of the BIOS screen, usually labeled as “Save & Exit” or something similar. Selecting this will prompt the system to save your modifications and restart.
- Confirmation Prompt: Some systems may present a confirmation dialog; you’ll often be required to affirm whether you want to save the changes before exiting.
A successful change means your computer will now boot according to the newly defined sequence upon the next restart.
Troubleshooting Common Boot Order Issues
Even seasoned users can encounter hiccups while trying to change the boot order. Here’s how to troubleshoot common problems.
Unable to Access BIOS
If you’re having trouble entering the BIOS setup:
- Timing is Crucial: Ensure you are hitting the designated key immediately after powering on. Timing can be tricky, so try again if you miss it.
- Consult the Manual: If unsure about which key to press, the motherboard or laptop manual may provide specific instructions.
Boot Device Not Recognized
Sometimes, even after modifying the boot order, the desired device may not be recognized.
- Check Connections: Ensure that cables connecting external drives are secure. For internal drives, check the connections on the motherboard and power supply.
- Format the Drive: If you’re trying to boot from a USB or external HDD, ensure it’s formatted correctly and contains a bootable image.
Changes Not Persisting
In some cases, you may find that your changes aren’t being saved.
- BIOS Update: An outdated BIOS could lead to issues. Check the manufacturer’s website for an update.
- CMOS Battery: A failing CMOS battery can cause BIOS settings to revert back to defaults. Consider replacing the battery on the motherboard.
Understanding common troubleshooting techniques can empower you to handle potential challenges effectively.
Frequently Asked Questions
What does changing the boot order do?
Changing the boot order determines which device your computer will attempt to boot from first when starting up. This is especially useful when you want to install a new operating system or troubleshoot issues.
Can I change the boot order in Windows?
No, the boot order is set within the BIOS/UEFI settings, not directly within the Windows operating system. However, you can access BIOS settings through Windows by restarting and using the appropriate key during the startup process.
Is it safe to change the boot order?
Yes, changing the boot order is generally safe as long as you know which devices you are prioritizing. Be cautious with unfamiliar settings or devices to avoid unintentional issues.
What happens if I don’t change the boot order?
If you don’t change the boot order, your computer will continue to boot from the default device. If the operating system on that device is corrupt or missing, it may fail to load.
Can I reset the boot order back to default?
Most BIOS setups offer a “Load Defaults” option, allowing you to revert all settings back to factory defaults, including the boot order. Just remember to save your changes afterward.
Conclusion
Learning how to change boot order in BIOS is an invaluable skill that enhances your ability to manage your computer effectively. Whether you’re aiming to troubleshoot issues or simply want to boot from a different device, understanding the BIOS setup and boot order offers substantial benefits. Remember to approach this process with caution and confidence, and you’ll navigate your computer’s inner workings like a pro. Embrace the knowledge and control you now possess over your system!
