How to enter the Windows 10 BIOS: Do you need to change settings in the BIOS of your PC with Windows 10 installed but you don’t have the slightest idea of how to go about it? Don’t worry, luckily I’m here, ready and well available to give you all the explanations you need. If you allow me a few minutes of your precious free time, I can in fact explain to you, with my guide today, how to enter the Windows 10 BIOS and believe me, it’s much simpler than you think.
The BIOS (acronym for Basic Input-Output System), in case I am not aware of it, is a software that resides in a chip placed on the motherboard of the computer and which contains all the instructions to start the system and to ensure that the hardware and software parts that make up the PC can communicate with each other. To access it, just put into practice a very simple procedure within the reach of anyone, the one I am going to show you in my dedicated tutorial.
Before giving you all the necessary information on what to do, however, it seems right to make a small but fundamental clarification. Starting with Windows 8.x and, consequently, also on Windows 10, the BIOS has undergone an evolution becoming UEFI (acronym for Unified Extensible Firmware Interface). Unlike the “classic” BIOS, the UEFI has a graphical interface, support for mouse and touch screens and has some advanced security features. To find out more, read on, find all the details you need right below.
Entering the UEFI
In order to enter the Windows 10 BIOS, or better to be able to access UEFI (considering what has been specified above), you can act in two different ways. You can access it with the computer on, going to the system settings and calling up a specific function, or you can do it when you turn on the PC, using a special combination of keys.
Which of the two modes to choose is a decision that obviously is up to you alone, based on what your preferences and actual needs are. The UEFI screen that you will later find yourself in front of is obviously the same in both cases. You find it explained how to proceed in one way and another below. Happy reading and good work!
From Windows 10
Do you want to understand how to enter the Windows 10 BIOS and your computer is already on? In that case, the first fundamental step you need to take is to click on button Start (there Windows flag located in the lower left corner of the screen) and select Settings (the icon with thegear) from the menu that opens.
Once done, click on the icon Update and security present in the window that opened, choose the item Restoration from the sidebar always on the left and click on the button Restart now placed under the wording Advanced startup.
Then wait a few seconds for the menu to appear with the system restart and restore options and select the following icons: Troubleshooting, Advanced options is UEFI firmware settings. Finally, click on the button Restart and wait a few moments, until the computer restarts.
When restarting, your Windows 10 PC will automatically enter the UEFI configuration menu. To move into the latter, you can follow the instructions found in the next step of the tutorial.
When the PC is turned on
If, on the other hand, your PC has not yet been turned on or in any case it is not possible to access the BIOS by turning it on because some problem has arisen, the system is compromised or higher simply because the items I have indicated to you in the previous lines are not available, you can cope with this by putting into practice an alternative procedure to that seen together a few moments ago, which in any case allows you to achieve your goal but which, however, should be clarified from the outset, may vary from brand to brand of computer (reason for which the indications I am about to provide you may prove to be not exactly precise).
So you ask me what to do? I’ll explain it right away! Turn on your computer by pressing on the power button on the body (in the case of notebooks) or on the case (in the case of stationary computers) and as soon as the first screen with the Windows logo is displayed, immediately press and continue to hold down the key for a few seconds F2 on the keyboard (if you are using a notebook) or the key Delete (if you are using a desktop computer), always present on the keyboard. You will then find yourself in front of the UEFI configuration screen.
In case the key combination I just suggested you use should prove ineffective, you can try replacing the keys F2 or Delete with F6 or F10.
If you can’t access the BIOS of your Windows 10 PC by doing so, try taking a look at User Manual computer or try to see if the right combination of keys to use is indicated during the boot phase of the PC, in the first screen that appears after pressing the computer’s power button and before the system logo. The information is generally shown in the lower left part of the screen.
In the unfortunate event that the information I have just given you should prove to be inaccurate or in any case whether you believe you need more details, I suggest you take a look at the section dedicated to the support and assistance of your company’s website. computer. You will surely find them the answers to your doubts. If it can help you, here are the links to the relevant section of the websites of all the major PC manufacturers.
Change the UEFI settings
At this point you should finally find yourself in front of the UEFI configuration panel. It is essentially a screen organized in tab where there are all the settings of your PC Window 10.
However, considering that the menu structure is not the same on all computers, unfortunately I will not be able to provide you with exact indications in this regard. In any case, do not worry, I will try to explain myself in such a way that you can still be able to easily identify the options of your interest. In addition, you can also help with the information provided by the official support of the manufacturer of your PC (which you can access using the appropriate links that I have given you a few lines up) as well as with the dedicated assistance page attached to the Microsoft website.
Without this necessary premise, let’s move on to the facts! First of all, keep in mind that to move in the UEFI you have to use the directional arrows keyboard: Up down to select an option e Right left to change its value or to switch from one tab to another if the menu at the top of the screen is selected. By pressing the button instead Submit you can select an option to change its value.
Let’s move on to the various sections into which the UEFI menu is divided. It is usually divided as follows but keep in mind that the title of the cards can also change depending on the computer in use.
- By accessing the card Main find the settings relating to the date, time and information on the computer in use.
- By accessing the card Advanced find advanced settings on processor (CPU), network, USB ports and so on.
- By accessing the card Security you will find the settings on the Secure Boot (if available) and those relating to the UEFI password protection.
- By accessing the card Boot find the options to go to change the order of the boot devices and those to enable the Legacy BIOS mode (if available).
- By accessing the card Save & Exit find the settings to exit UEFI by saving and applying the changes made to the relevant settings, not saving them, or restoring the default values (i.e. factory settings).
Among the various settings available, those attached to the card Security and in particular those referring to Secure Boot, to the Legacy BIOS and ai boot devices they are those that have the greatest relevance for what concerns the installation of a new operating system (as well as its execution in “live” mode). Below you will find more explanations about it. Ah, almost forgotten, they are functions present on all computers, regardless of brand and model!
- Secure Boot – This is a UEFI security function thanks to which the execution of operating systems without a specific digital signature is immediate. To allow the execution of operating systems that do not have a valid digital signature (this is the case for many Linux distros) and therefore to disable this setting, you must go to the tab Security of the UEFI, you must select the item Secure Boot menu, then the option Secure boot and then you have to set the latter to Disabled.
- Legacy BIOS – This is a function that allows you to emulate the old BIOS on computers equipped with UEFI. It can be useful to be able to install all those operating systems that do not support UEFI (as in the case of Windows 7). To set the aforementioned mode on your Windows 10 computer you have to go to the tab Boot of the UEFI and sector the option Boot mode up Legacy BIOS.
- Boot device order – It is essentially what the computer follows to boot. In other words, if you want to start an operating system that you have on a pendrive, you must set the boot order by making sure that the USB port comes before the PC hard disk (therefore before the operating system installed on the computer). Changing the order of the boot devices is simple. To do this you need to access the card Boot of the UEFI and select the option Boot Option # 1 on the device of your interest.
After making all the necessary changes to the UEFI of your PC, go to the form Save & Exit, choose the option Save Changes & Exit and answer in the affirmative (Yes) to the notice that is shown to you on the screen so you can save the changes made, restart your computer and start using it normally.
To conclude, I point out that if you need to check if your computer is normally using UEFI or the Legacy BIOS mode you can easily do it by typing the command msinfo32 in the Windows 1o Start menu and pressing the key Submit on the keyboard. In the window that you will see appear on the desktop, choose the item System resources in the left sidebar and check if it corresponds to the item BIOS mode the wording is reported UEFI or that Legacy BIOS.
