Each BIOS or UEFI looks different and works differently, but most share basic principles for navigation. For menu driven BIOS or UEFI interfaces, your keyboard’s arrow keys  are used to access and enter menus. The settings for configuring boot options are sometimes hidden under submenus, which you will have to navigate using these keys.
On my HP desktop, the option for changing the system’s boot order is located under Storage > Boot Order. On my other computer, an HP Elitebook, the boot order is called Boot Options located under the System Configuration tab, which uses a graphical interface. So, the experience will vary depending on the system you are using; even if they are the same brands. Navigate through these interfaces by browsing and looking for logical labels that might suggest what you are looking for – storage, boot, disks, etc.

How to Change the BIOS / UEFI Boot Order to Boot from a USB / CD Drive

Once you’ve found the Boot Order menu, the interface will present menus displaying the structure of your boot order. Boot order determines which devices your computer will try to boot from first, second, etc. when you turn it on.  Most often, your first boot device is your hard disk or SSD containing Windows 10. You can also have your DVD, CD or USB thumb drive, set as the first boot device without it affecting Windows 10 loading into main memory. If you have a removable storage device set as your first boot device the BIOS will check if there is any attached removable storage as part of POST (Power On Self Test). If a USB thumb drive or DVD is detected, the system will prompt you to boot from it before loading any existing operating systems on the local disk.
Moving through the options will require using the arrow keys. If you don’t see your connected USB device listed, choose the USB storage listed under EFI or Legacy sources. Use the down arrow key to navigate to the selection; some older BIOS interfaces will require using function keys such as F5 and F6 to navigate up and down the boot order. After selecting the appropriate option, you will need to confirm these changes; pressing F10 will usually save them. If not, read the on-screen instructions, which will identify the appropriate function key for saving or accepting changes.
Tip: Instead of changing the boot order, some systems will let you boot directly into a certain device as a one-off. Check out the section below on the boot device menu / boot override.

Booting from a USB drive or CD/DVD

Once the desired option has been selected and confirmed, depending on the type of installation media you are using, you might see different options. USB media will immediately boot into a Windows Boot Manager, prompting selection of the architecture of Windows 10 – 32 or 64 bit – you would like to install.
If you are installing from DVD media, Windows 10 setup will prompt you to hit any key on your keyboard to load setup.
From there, you should be home free. As long as you created your bootable installation media correctly, the on-screen instructions should guide you through the rest of the process.

Troubleshooting Boot Options

Some systems might encounter problems when attempting to boot from removable media. If you are following the steps above to a T and you’re still having issues, look into some of the items below.
  • Accessing the UEFI setup page on a Microsoft Surface device. The steps for accessing the BIOS / UEFI page on Surface devices are a bit different. See the steps below for Setting Up UEFI on a Microsoft Surface.
  • Changing UEFI settings on an out-of-the-box Windows 8 or Windows 10 device. For computers that you buy with Windows 8 or Windows 10 pre-installed, it may be tricky to access the UEFI / BIOS. See the steps below for Configuring UEFI on Windows 8 or Windows 10 Computers.
  • What about Mac? Apple computers support installing Windows, but they don’t have a BIOS / UEFI setup page like your typical PC. See our section on installing Windows on a Mac below.
  • Make sure the bootable media was created properly. Boot issues can sometimes be attributed to how the install media was configured or prepared. For instance, on UEFI-based systems – systems designed for Windows 8 or later – preparing the install media, if downloaded from the Microsoft software page, will require using the Microsoft Media Creation Tool or a third-party utility such as Rufus.
  • Enable Legacy Boot Sources. If you are installing on an older computer using BIOS, selecting the option under Legacy Boot Sources or Legacy USB will let you start Windows setup from a USB or CD drive.
  • Disable Secure Boot. Security technologies included in UEFI such as Secure Boot can be a blocker and prevent the system from booting external storage sources. Disabling Secure Boot, temporarily—normally accessible under the security menu or tab—will often resolve this.
  • Disable Fast Startup. If you are unable to access the BIOS, you may need to disable Fast Startup, if it is enabled.
  • Resetting BIOS settings. Some BIOS / UEFI setup screens have a factory reset option. This can sometimes be a quick fix but proceed with caution. If you have your drive BitLocker encrypted with TPM enabled, this may make your existing system drive unusable. OF course, this is a non-issue if your goal is to reinstall your operating system from scratch.

Disabling Fast Startup

If you are attempting to load the firmware on a computer already running Windows, this might prove difficult because of the Fast Startup setting that might be enabled. Fast Startup was first introduced in Windows 8 as a way to make Windows start quicker after shutdown by caching key pieces of operating system code.
If you are experiencing problems loading your BIOS or UEFI or changing your boot order, start Windows then turn off Fast Startup.
  1. Press Windows key + X
  2. Click Power Options
  3. Click Choose what the power buttons do
  4. Click the link Change settings that are currently unavailable
  5. Under Shutdown settings, uncheck Turn on fast startup (recommended)

Boot Device Menu / Boot Override

Some computers will let you press a function key that takes you to a direct menu where you can immediately choose, which volume: USB thumb drive, SD Card, external hard disk, local disk or optical media you would like to boot from. Dell and HP systems, for instance, will present an option to boot from USB or DVD after striking the F12 or F9 keys respectively. This boot device menu is accessed once you’ve already entered into the BIOS or UEFI setup screen.
Here is a list of commands for accessing the direct boot menu on popular brands:

Microsoft Surface and Modern Windows 10 Devices

The Microsoft Surface uses its own unique interface for booting into the UEFI firmware interface.
First, you need to access your BIOS / UEFI setup utility on your Surface.
  1. Make sure your Surface or Surface Pro is fully powered down.
  2. Press and hold the volume up button located on the left side of the device.
  3. Press and hold the power button for five seconds located on the top of the device.
  4. Release the power button after five seconds but continue to hold down on the volume button until you see BIOS UEFI.
The Surface uses a combination of text-driven interface, touch, and mouse input to modify boot settings. Navigate down to the option Configure Alternate System Boot Order using the down arrow key. Hit the Enter key, which will load a submenu; use the up and down arrow to select the first boot device then hit Enter.
Navigate down to the Exit setup menu, hit Enter, use the left or right arrow keys to select yes then hit Enter.

Configuring UEFI on Windows 8 or Windows 10 Computers

If your computer or device is already running an existing version of Windows 8 or Windows 10, you might be able to initiate booting from removable storage from within the operating system. Click Start > Settings> Update & security > Recovery. Then, under Advanced startup, click Restart now.
If this option is not available, sign out of Windows 10, then hold down the shift key, click the Power menu, then click Restart. Continue to hold down the shift key then wait until the Recovery environment is loaded. The Choose an option menu lets you access and boot from removable media attached to the system.
If you need to access advanced boot options, click Troubleshoot, then click the UEFI Firmware Settings to make further changes.

What About Mac?

For the past 10 years, Apple Intel-based Macintosh computers have supported Windows. Most Macs will allow you to boot from a CD by pressing and holding C on startup. Booting an operating system other than OS X or macOS from a USB drive is a little more involved. We previously covered preparing your Mac for installing Windows 10 using the Boot Camp wizard in macOS. After preparing your boot camp partition and install media, booting from it is as simple as holding down the Option key before you hear the startup chime.

Conclusion

One of the lessons users will learn from this is that not all computer configurations are alike, even if they are from the same brand. Hopefully, reading through this guide has given you enough background knowledge about the process to help you configure your particular system, or at least ask the right questions if you run into trouble.
