BIOS/UEFI Setup Guide: Boot from a CD, DVD, USB Drive or SD Card

Windows runs on thousands of computer configurations, but installing a new operating system like Windows 10 on the variety of configurations that exist is another thing. The steps may be different depending on whether your computer has an existing Windows 10 installation on it, an earlier version of Windows on it or a completely different operating system on it, like macOS or Linux. In each case, installing Windows 10 relies on booting from a device other than your main hard disk drive (HDD) or solid state drive (SSD). To do that, you need to access the BIOS or UEFI setup page. Sometimes, this is easier said than done.

In this guide, we’ll walk through the basic steps that apply to most scenarios. Then, we’ll discuss some troubleshooting and alternate methods, in case the simple approach doesn’t work for you.

  5. Booting from a USB/CD/DVD Drive or SD Card. Once you’ve configured your BIOS / UEFI correctly, here’s what to do.

Best case scenario, those steps will get you up and running. If not, see our Troubleshooting section. This includes details for changing the boot order on a Microsoft Surface device and booting from another device on a Mac.

NoteOnce you master the steps to boot your computer from a USB or CD/DVD, you can use this to boot other operating systems or bootable live environments on your machine.

BIOS vs. UEFI: What’s the Difference?

Each computer, whether it’s a DELL, HP, Acer or even a custom built system, is an island unto itself before Windows 10 (or some other operating system) starts. Since the 1980s, hardware vendors have worked together to standardize around common access routines and commands for managing your BIOS Boot Options. The BIOS, which stands for Basic In Output System, is a critical bit of low-level code stored in nonvolatile memory that your computer uses to manage your hardware and load Windows 10 or another operating system.

A new standard called UEFI or Universal Extensible Firmware Interface came online a decade ago and became the standard for new PCs and devices preinstalled with Windows 8 or later. UEFI offers more advanced options than BIOS, with support for features such as a graphical user interface and mouse support, making it easier to configure boot and hardware settings. UEFI also supports recent security standards required by Windows 10 and previous releases such as Secure Boot, which maintains the integrity of a computer’s state and prevents malicious code from compromising your system at boot time. After decades of systems using BIOS, malware has become more sophisticated, where it is even possible for malicious code to easily infect key operating system code such as the Master Boot Record.

How to Access Your BIOS or UEFI Setup Screen

Because of the variety of brands and configurations, and the ongoing revisions to these systems, this article is not exhaustive. That said, the following provides a comprehensive list of common methods for booting into the BIOS or UEFI firmware interfaces.

To enter the BIOS, you need to press a certain key or combination of keys while your computer is booting up. Usually, your window to do this is very brief—you have to press the button when the splash screen with the manufacturer’s logo is displayed. If it seems like your computer boots too fast for you to get a chance to hit the button, you may need to disable fast startup.

Here is a list of the common functions or commands for loading the BIOS. Please note, your BIOS screen might display a hint to indicate the appropriate function key for loading the firmware. Start your computer then proceed to strike the appropriate key or command to load the BIOS. After loading the BIOS or UEFI, connect your USB media or connect the DVD install media.

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 sub menus, 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:

Brand

Command

Acer

Esc / F9 / F12

Asrock

F11

Asus

Esc / F8

Compaq

Esc / F9

Dell

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 sub menu; 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.

    Definitely one of the most useful recent groovyPosts.

    Now that very large (e.g., 128 and 256 GB) thumb drives are available,
    how about a related article on how to create a bootable thumb drive as
    a backup for a currently functioning Windows 10 system…in case the
    system’s hard drive or ssd drive fails. Assume that the user never had
    a Windows 10 installation CD because the system either came with
    Windows 10 already installed or was upgraded via the (now expired)
    free upgrade program.

      Thanks Robert, will add it to my list of content ideas. If you are running Windows 10 Pro, there is already a solution in Windows to Go. I believe a third party option for Windows 10 Home is Rufus.

    Hi guys, I was not aware of the UEFI configs so after trying to boot my Packard laptop from USB/DVD drive and had an issue of the laptop only displaying the HHD on the boot option no matter how good I configured the BIOS. I then opened the laptop,took the HDD and formatted it using my desktop, what I noticed is that I deleted the recovery and security partitions that were on the HDD.so now when put the HDD back to the laptop the laptop says no bootable device.it does not display any of the three “HDD,USB,DVD ROM” which I think it uses UEFI settings that were on tone of the partitions that I deleted from HDD.is there a way to get the UEFI to the partition or fiddle with the bios to end up installing windows or any other way please help

      have seen noted either here or elsewhere that part of your problem may be the missing partitions. Not the content, but the lack of those partitions. Your BIOS / UEFI routine is looking for the bootable drive to be whatever partition Number that your C:\ drive used to be. Try to recall what was there before the drive was wiped. Then use some drive partitioning software to add back in the missing partitions – ahead of what you have now. You may have to move the C: partition to make room, but the partitions you are adding can be small, but they have to be there.If you had, say, two partitions ahead of your old C:\ drive, your boot routine will be looking for the third partition to be the bootable one. I have found that one of the most valuable things I can do before changing or updating a drive is to go into Control Panel > Admin Tools >Computer Manager > Storage > Disk Manager and take a screen shot of the drives and their partitions and save that to a flash drive for future use.

      My current furball is a 5-year old laptop with a tiny 20GB SSD plus a boot drive with 5 partitions. Cloning that Win 10 / UEFI mess to a replacement drive when the boot drive has quite a few bad sectors is thoroughly non-trivial! The steps above are a definite help.

    Question: On a custom built desktop that was upgraded to Win-10, is it possible to change the BIOS to UEFI? I have been trying to get hyper-D to work but receive error that no UEFI located.

  5. Steve April 20, 2017 at 6:34 am #

    I am trying to get an image on to a corrupt Hannspree mini PC – With UEFI BIOS
    F2 fails to do anything – so how do I set the boot to either DVD drive or flash drive via USB Port ?

  6. John Ford April 28, 2017 at 7:24 am #

    Great post but thought I’d mention that later Toshiba laptops (mine is an R50B) need f2 held down while powering onto get into the setup.

    installing windows 8.1 or 10 on a mac via usb will not install normal sound drivers because of EFI boot

  8. hopeful July 27, 2017 at 10:28 am #

    I hope this is the right forum for the following.

    I have experienced a viral spyware attack in which they, whoever that is, started to delete files from my windows 10 hard drive before my very eyes. I immediately shut off my 2 pc’s. They contain files valuable to me which I want to preserve.

    My strategy to recover from this attack is to boot up with Linux from a usb drive.
    Then create a clone image of the hard drive and store that on an external hard drive purchased for this purpose. I would then convert the machine to 100% Linux hopeful that I will prevent further attacks. So my first question, “Is this a good strategy?”

    However in attempting to boot from the usb I find myself blocked. I click F2 on the load and it shows only one boot option, windows on the hard drive. I am using a Dell Inspiron. So I click on the reset options button and up pops a nice list of options with USB first. So I click on USB, enter the three lines of information including a reference to the live Ubunta USB flash drive I intend to use, and up pops a single line containing the USB directive at the end of the line, but at the beginning is the hard drive again. They are together as single choice. Clicking on F12 during startup shows a boot list with only one option, the hard drive. So I am guessing that whatever file contains the boot options has been maliciously altered. I have been researching the above and must say the situation is complex.

    Any good suggestions anyone?

    Thanks

    hopeful
