Inside the BIOS The BIOS Explained: Boot Order, Video Memory, Saving, Resets & Optimum Defaults The BIOS Explained: Boot Order, Video Memory, Saving, Resets & Optimum Defaults Your computer’s BIOS (basic input/output system) is the low-level software that starts when you boot your computer.

Entering the BIOS just takes a simple key stroke at the right moment while the system is booting. To save you the guesswork, we have compiled the different ways you can enter the BIOS.

As mentioned above, entering the BIOS is pretty simple. Unless your computer came with UEFI How to Update Your UEFI BIOS in Windows How to Update Your UEFI BIOS in Windows Most PC users go without ever updating their BIOS. If you care for continued stability, however, you should periodically check whether an update is available. We show you how to safely update your UEFI BIOS. Read More , e.g. on a new Windows 8 laptop, you just need to boot your computer, wait for the right moment, and hit the right key. Easy. These instructions, however, raise two questions: What exactly is the right moment and how can you find out the right key?

If you have a Windows 8 device with UEFI, scroll down for instructions.

What Is the Right Moment to Enter the BIOS?

The right moment is sometime between powering on the computer and before the operating system is launching. The window is so narrow because the BIOS essentially only initializes your hardware, before handing over to the boot loader, which boots the operating system. Once the operating system is starting up, often indicated by the display of the respective logo, you missed the moment.

Starting Windows

You might see a message that indicates the right moment. It most likely says something like “Press <DEL> to Enter Setup“, meaning it also reveals which key to press.

Enter Setup or BIOS on a PC

In the absence of such a message, the right moment generally is when manufacturer logos are displayed, prior to the booting of the operating system. And the easiest way to not miss the time when you can enter the BIOS, is to press the right key even before you power on the computer and hold it until the BIOS comes up. If that doesn’t work, you’re not pressing the right key or something is broken.

This leaves you with the second question:

What Is the Right Key to Enter Setup?

As you already gathered, it depends on your hardware. More specifically, it depends on the motherboard, as this is where the BIOS is located.

Common keys to enter the BIOS are F1, F2, F10, DEL, ESC, as well as key combinations like CTRL + ALT + ESC or CTRL + ALT + DEL, although those are more common on older machines. Also note that a key like F10 might actually launch something else, like the boot menu. The exact key or key combination depends on your computer manufacturer and model.

You can proceed with trial and error until you find the right key, press multiple different keys at once and get lucky or consult the list below.


The most common keys to enter Setup on Acer hardware are F2 and Delete.

On older computers, try F1 or the key combination CTRL+ALT+ESC.

If your computer features an ACER BIOS, you can restore the BIOS to bootable settings by pressing and holding the F10 key. Once you hear two beeps, settings have been restored.


As with Acer, the most common key is F2.

Depending on your model, it might also be the Delete or Insert key, and less commonly F10.


On a newer Dell computer, try the F2 key while you see the Dell logo.

Alternatively, try F1, Delete, F12, or even F3.

Older models might use CTRL+ALT+ENTER or Delete or Fn+ESC or Fn+F1.


Keys most commonly used on HP machines to enter setup include F10 and ESC.

On some HP computers F1, F2, F6, or F11 will open the gates to the BIOS.

On HP Tablet PCs F10 or F12 will get you into the Setup.

HP has compiled information on its BIOS here.


The F1 or F2 key should get you into the BIOS.

Older hardware might require the key combination CTRL+ALT+F3 or CTRL+ALT+INS or Fn+F1.

If you have a ThinkPad, consult this Lenovo resource: how to access the BIOS on a ThinkPad.


On a Sony VAIO, F2 or F3 will get you into the Setup, but you can also try F1.

If your VAIO has an ASSIST key, try to press and hold it while you power on the laptop. This also works if your Sony VAIO came with Windows 8.


Your best bet is the F2 key.

Other candidates include F1 and ESC.

On the Toshiba Equium F12 will enter the BIOS.

Toshiba also has more detailed instructions on how to access the BIOS.


Unfortunately, there is very little consistency. Neither do computer manufacturers always use the same motherboard manufacturer, nor do motherboard manufacturers consistently define the same key for entering the BIOS. If you want a definite answer on which keys to press to enter Setup, you have to search for the exact model of your computer’s motherboard.

    Thank you. My ASUS computer says e “Press CTRL + S to Enter Setup“, but when I press that (or F2 or F10) I am taken to a windows boot selection screen where I am shown the path to windows and asked whether to send or escape. Pressing escape takes me to windows. I presume that send will send the path and take me to windows.

      Sorry, I was pressing CTRL S at the wrong moment (too soon I think).

      Pressing CTRL + S when prompted leads me to a screen that looks like a BIOS scree, with white writing on a blue background but it is not the BIOS but
      Intel Boot Agent GE v1.3.98 Setup Menu
      This is like a BIOS with very few options. They are
      Network Boot Protocol PXE (unchangeable)
      Boot Order Use BIOS Boot Order (unchangeable)
      Show setup prompt (dispaly CTRL + S or not, can turn off) currently enabled
      Setup Menu Wait Time 0,2,3,5 Seconds (currently 2)
      There is this from Intel
      which I installed but I do not know how to run it. No program is in the start menu. There is now (and perhaps before) an Intel22.1 folder in C (rather than program files) which contains a C:\Intel22.1\APPS\BootUtil\Winx64\BOOTUTILW64E.EXE which when run flashes a DOS window for less than a second. In the same folder there was a readmefirst.txt file which I did not read first that says

      Installing this utility will overwrite some files required for Intel(R) PROSet for Windows Device Manager. This may result in system bug checks or loss of functionality when using Intel(R) PROSet or other tools using the same driver. Please uninstall Intel PROSet before installing this utility.
      Note that re-installing PROSet later on could render this tool useless.

      I have no idea what PROSet is is. I just want to get to my BIOS (a sata drive is not being recognised and word is that a BIOS setting may need to be changed).

      I will try to reboot again.

      Eventually i found the key for my ASUS M4A89GTD PRO/USB3 and it is DELETE, which is not displayed on start up (only CTRL +S).

    No keys or combination of keys will get me into setup on this infernal asus mobo! Does that mean the mobo is dead? Everyone is acting like you can always get into setup when you cannot always do that! Everyone is talking in big circles! Why is setup not there?

      You could use your computer's restore options, i.e. booting Windows through the recovery partition, or a recovery disk to boot into the BIOS.

      If you don't have a recovery partition or a Windows 8 recovery disk and can't create one now, try to hit potential "Enter Setup" keys while your computer boots. I'd try ESC, DEL, and F keys, and combinations described above. You might trigger the BIOS boot after all.

      Good luck and do let us know what worked for you in the end. Thank you!

    On Dell Computers, is there really a 'Fn' Key? As in Fn+Esc. I've never seen a Fn Key without the 12 numbers... unless you mean the F Lock key. I"m sitting here at my keyboard, which is a Giant Microsoft full-size all- featured keyboard and I don't see a Fn key. Are you messing with my head?

    (or am I really going to look dumb, when you tell me which key it is....)

    • Tina S
      February 9, 2014 at 5:28 pm


      it depends on your model. As I wrote, the Fn key combination was used on older Dell models. Generally, computers with full-sized keyboards don't have an Fn key as there is space for the number pad.

    On the Acer Chromebook, it is impossible to enter the BIOS, unless you open the machine and remove the tape "which may void your warranty". Regrettably...
