How to enter BIOS settings from a DELL computer/laptop?
Most often, on DELL laptops, to enter the BIOS settings, you need to press the F12 key (sometimes F2 or delete) when turning on the computer. There are a lot of things you can change there. For example, speed up the processor (not advisable), change the hard drive settings (for Windows boot or other OS). But the most amazing thing is that you can set three passwords on your laptop: administrative, system and hard drive password (the correct order for setting passwords). And if the passwords are all different, then when you turn on the laptop you will be asked for at least 2 passwords. But here it is important to know that now on laptops, if you lose your password (forgot your password), it may only be possible to recover it at a service center. It’s unlikely that you can do this yourself at home, because... turning off the battery on motherboard does not reset the password.
And by the way, you can uncheck the boot disk from the OS when you turn on the computer, which will not allow someone who wants to “dig” into your computer to “destroy” the OS. But it is advisable to set a password on the OS. Then on your computer, in order to get to your data, you will have to enter 3 passwords: admin or system, hard drive and OS.

Knowledge base
Want to know what BIOS is and how to check and change BIOS settings on your Dell computer? This article provides details.
Note. For information about resetting and clearing the BIOS, see the following knowledge base article:
- Reset BIOS or CMOS and Clear NVRAM on Dell PC
The abbreviation BIOS stands for Basic Input Output System. BIOS is software on a small memory chip motherboard PC (CMOS - complementary metal-oxide-semiconductor structure). This system settings software acts as an interface between the PC hardware and the operating system (such as Windows), allowing the software to control the computer's hardware components.
The BIOS also contains the algorithms by which the PC performs basic actions, such as booting over a network or using hard drive, determining in the latter case the order in which the disks are used.
BIOS is also used to identify and configure the computer's hardware components (hard drive, floppy drive, optical drive, processor, memory, Plug and Play devices, etc.). This process is performed using ESCD (Extended System Configuration Data), which is typically stored in an additional non-volatile memory NVRAM.
As technology has advanced, this process has changed, but users still refer to BIOS as both CMOS and NVRAM despite their slight differences. The CMOS contains the BIOS and its settings, and the NVRAM stores the ESCD data. However, updating the BIOS does not clear NVRAM.
To enter BIOS or System Settings on your Dell PC, press the F2 key when the Dell logo appears on the screen when your PC boots up. (Fig. 1)

2. Why is it necessary to update the BIOS?
Dell recommends updating the BIOS according to the update cycle schedule. As with new versions of the operating system and drivers, these updates contain relevant improvements or changes that are compatible with other system components ( Hardware, firmware, drivers and software), security updates and system stability improvements.
Unlike Windows updates And antivirus programs, which usually boot automatically, you must update the BIOS manually.
Dell provides a self-installing update package that makes the task much easier.
Attention! Before the process starts BIOS updates always follow backup data, since any error can lead to data loss.
3. How to find out the BIOS version
There are several ways to find out the BIOS version, but the easiest is to look at the system information.
For Windows 8 and 8.1 editions, type run on the Metro screen. Then press Enter, type msinfo32 in the Run dialog box, and click OK.
For Windows 10, type msinfo32 in the search bar and press Enter.
For earlier editions of Windows, you can access system information by clicking the Start button and then clicking Run. In the Run dialog box, enter msinfo32 and click OK.
In the system information window that opens, the system summary information item should be highlighted in the navigation panel on the left. The BIOS update version/date can be viewed in the summary window on the right (Figure 4).
Rice. 4. System information
You can also find out the BIOS version using command line.
Click Start. In the Run or Search dialog box, type cmd, and then click cmd.exe from the search results.
When the User Access Control window appears, select Yes.
In the Command Prompt window, at the C:\ prompt, type systeminfo and press Enter. The BIOS version will be displayed in the results (Figure 5).

Greetings, my dear readers. The topic of our conversation is how to enter the BIOS on a Dell laptop. This technique has become quite popular and poses serious competition. personal computers other brands. But even with a stable working system, sometimes there is a desire to improve something and for this you need to enter the system settings.
To enter the BIOS on a Dell laptop, remember that universal method there is no such thing as there are several determining factors:
- a key provided by the manufacturer (or a combination thereof) to enter system settings;
- BIOS type;
- laptop model and year of manufacture. These can be PCs for work or for home, for example, the popular Inspirion;
- type and version of the operating system;
How to select the right button?
But let's talk about everything in order. First I'll talk about general principles entering the BIOS. In most cases, this procedure begins when the computer is turned on. If it works, then it needs to be rebooted.
This starts the process of checking the internal parameters of the PC, and before the operating system starts loading, you must press certain keys. Which ones you can see on the screen; usually this information is present. But if it’s not there, here are some options.
- Fn+F2
- Delete
Sometimes a quick, constant click from the moment you turn it on helps, and in other cases the “Shift” button comes to the rescue. There are two options: either the system is buggy and you will have time to start the BIOS, or “Ten” will load and then you will need to reboot with “Shift” pressed. This will take you to the system recovery menu, through which you can enter the BIOS (by going to “Diagnostics” - “Advanced options” - “UEFI firmware settings”).
Also, if you want to have time to enter the BIOS during the next restart, you can simply disable fast boot in the system power settings.
Don't be surprised, but BIOSes are different
I think everything should work out for you. For those who are going to work in the BIOS for the first time, I will tell you what it looks like. U simple models, like the early Inspirions, you will find a familiar interface with Main, Advanced, Security, Boot and Exit tabs. This will help you navigate the settings.
Over time, the BIOS interface of Dell laptops began to change, and in the Inspirion 1525 you can find this version of the extended menu and the transition from the tab menu to a view similar to “Explorer”
But modern advanced models like Vostro, XPS , The Latitude BIOS has been further developed and has become completely different from the system settings of other manufacturers.
And this is good, because, as for me, it is more understandable and all the important sections are highlighted here separately. A minimum knowledge of English will allow you to quickly find and correctly set the necessary parameters.
Well, friends. Now you know how to enter the BIOS on a Dell laptop and can easily navigate its settings.
With this I say goodbye to myself and wish you good luck.
These methods will allow you to enter the BIOS for other Dell laptops.
The other day I came across a strange Dell Inspiron 7737 laptop, with a damaged and “unbootable” operating system Windows system 7, on which neither the BIOS entry (F2 key) nor the boot menu using the F12 key worked, the case was not very standard and we had to deal with a simple problem in more detail.
Dell Inspiron 7737 BIOS Standard Entry
According to the instructions, to enter use the F2 key or the Fn+F2 key combination (if the Function Key Behavior option was enabled in the BIOS).
Since the boot moment passes very quickly, I recommend turning off the laptop and entering the BIOS by simultaneously pressing the ON key and F2 (or the Fn+F2 combination).
In my case, these combinations worked and the laptop confirmed the transition to the BIOS, but still went to the point of loading Windows or to the DELL diagnostic wizard.
Entering BIOS through the Windows 8 interface
This method is used if you have installed Windows 8 in UEFI boot mode.
To enter the BIOS this way:
- Press combination Windows keys+ C (or move the mouse cursor to the upper right or lower right corner of the desktop), the Charm Bar toolbar will open
- Select an item Options
- Select an item Change computer settings A
- In the Computer Settings window that opens, select Update and recovery
- Select an item Recovery, item Special download options, press the button Reboot now
- The computer restarts and the Select Action window opens, go to Diagnostics
- Paragraph Extra options
- Click on the item UEFI Firmware Settings
The laptop reboots automatically by entering the BIOS.
In my case this method It also didn’t work, because during installation the laptop was switched to Legacy mode and the UEFI item was missing in recovery mode.
Entering BIOS by battery level
The third way to enter the BIOS of the Dell Inspiron 7737 is to discharge the laptop battery to less than 10%, this method takes time, but to speed up you can run the built-in diagnostics of the laptop and connect some external devices such as flash drives, or load any of the LiveCDs.
Once the laptop's charge drops below 10% (in my case at 3% charge), turn off the laptop and turn it on again.
The following message will appear on the screen:
Image 1. Message on the Dell Inspiron 7737 power-on screen when the battery is low
Press F2 and you will successfully enter the BIOS.
This method helped me, I entered the BIOS, turned on UEFI mode and was able to install Windows 8.
But the problem with entering the BIOS remained the same; the laptop confirmed pressing the F2 key, but it skipped entering the BIOS or the boot menu.
Updating the BIOS version
The fourth way to enter the BIOS of the Dell Inspiron 7737 is to update the BIOS to latest version.
In this laptop model, this can only be done from the installed operating system, since the BIOS file is released by Dell only as a Windows .EXE file.
Let's go to official page Dell Inspiron 7737 laptop support - link.
Open the BIOS section and download the latest version of the Dell Inspiron 7737 System BIOS file (at the time of this article, version A13)
Before starting the BIOS update process, close all unnecessary programs, connect power to the laptop and, if possible, disable the antivirus.
Run the downloaded file like 7737A13.exe and wait for the update process to complete, the laptop will automatically reboot and the installation progress will be shown on the loading screen. The laptop will reboot again.
After the second reboot, entering the BIOS will be successful in most cases.
In my case, the login problem lay precisely in the incorrect BIOS; after the update, the F2 and F12 buttons worked correctly.
Resetting the laptop's CMOS memory
And the fifth method, if none of the previous points helped you.
To with my own hands To reinstall the operating system on a Dell laptop, you need to go into the BIOS. BIOS is a basic information input and output system. It is installed on all laptops.
Entering the BIOS is done to prioritize booting from hard drives, changing the date and time on the laptop, monitoring it. CPU cooler speed, random access memory– all this is controlled by the user from the BIOS.
Attention! When you boot the laptop, “Press Del to Set Up” is displayed in the lower left corner of the screen. Usually the key that the system asks you to press is the entrance to the BIOS.
On laptops with Windows 7 and XP
A distinctive feature of Win7 is the display of a post-check window. Thanks to it, the user will be able to press several times the desired key and login.
To open the BIOS on a Dell laptop from Windows 7 or an older version of XP, the user must:
- Turn off the device.
- Turn it back on. When the laptop boots quickly, press the F2 button on the laptop keyboard several times. F2 is the trigger to enter the BIOS in Dell models such as Inspiron and Presicion. In the Dimension and Optiplex modifications, instead of this button, the role of the input key is played by Delete or Del.
- The settings window will appear on the screen. If installed security code To unlock the input, you need to enter it.
- Now the user will be able to make the necessary amendments to the system.
- To save these changes and continue using Windows, you need to click on F10.
- The system will ask: “Save settings and exit”? To confirm the changes, you need to left-click on “Yes” on the monitor.
- The computer will remember the settings, reboot and the user will be able to continue working with Windows OS or will install it.
Attention! Pressing a button once to enter an input/output system does not always work. Sometimes it takes two or three tries to get into the BIOS.
To log in to a Dell 4400 modification, the user must do the following:
- If the gadget is turned on, then reboot it.
- When the logo of the company that produced the laptop appears, have time to click on the F12 key.
- Press your finger on it until the settings window appears on the screen.
- Next, repeat steps 4 - 7 from the previous description.
And the Dell 400 modification uses a completely different button, unlike previous types of laptop. Therefore you need:
- Reboot Dell 400.
- While it is loading, quickly press one of the keys or alternately both: F1 or F3.
- Repeat steps from steps 4 to 7 of the very first description of entering the BIOS.
If the modification of the laptop is already quite outdated, then another key will be required. In this case, the instructions change:
- You need to log out of the system by pressing Ctrl + Alt + Del on the laptop keyboard at the same time.
- The device will reboot.
- Have time to press the Del button several times.
- Register the necessary settings in the input/output system.
- Use the F10 button to save the settings and click “Ok”.
You can log in to Windows 8 and 10 directly from the operating system. These OSes do not have a post-check window because they use fast boot mode. Now in these operating systems the BIOS is called UEFI. 
UEFI is a new type of motherboard firmware. It supports heavier volume hard disks, loads quickly and is secure.
On laptops with Windows 8 and 10
To enter Bios on a Dell laptop, the user needs to use the following instructions:
- Open the operating system desktop.
- Move the mouse cursor to the upper right position.
- A menu will appear on the right side of the laptop monitor.
- Click the “Options” button.
- In the window that opens, select “Change computer settings.”
- Several sections will appear on the screen. Click on the tab titled: “Update and Recovery”.
- Find the “Recovery” item in the window that opens.
- Click on it with the left mouse button.
- Find the "Restart" button. Click on it.
- Wait until the laptop reboots.
- The laptop will enter the recovery menu.
- Now the user needs to open the “Diagnostics” item.
- Then go to the Advanced Options tab and finally select Embedded UEFI Options.
Now the user can use BIOS settings to improve computer performance or to boot from removable media. To save the changes and exit, he will need to click on the F10 button on the Dell keyboard and press the “OK” key.
On older Dell models, enter the BIOS as follows:
- You need to open the Windows 8 or 10 desktop.
- Move the cursor to the upper right corner.
- In the drop-down menu, find and click on the “Options” button.
- Press the “Shutdown” button.
- Press Shift on the laptop keyboard and hold it.
- After the laptop reboots, go through the same tabs that were indicated in paragraphs 12, 13, 14 previous instructions to log into Windows 8 and 10 I/O systems.
- Save changes to BIOS settings and exit using the F10 button.
For this type of operating system, there is another option for entering the BIOS, this is the command line. You need to do this:
- Click the “Start” button in the lower left corner of Windows.
- IN search bar enter “cmd.exe”.
- The “Open command line as administrator” option will appear in the menu. Click on it.
- A command prompt dialog box will open on your desktop.
- Write the following code in it: shutdown.exe /r /o.
- The user will see the laptop reboot and various settings appear on the screen.
However, the user can remove quick start in Windows 8 or 10 to use standard keys to enter the information input/output system.
How to disable fast startup
The POST verification window turns on on Dell laptops with operating systems Windows 8 or 10 as follows:
Attention! If the BIOS settings are lost and the PC owner has forgotten the parameters that were set, he can always reset them to factory settings. He needs to remove the battery, disconnect the CMOS battery on the motherboard and wait twenty minutes. Then plug it back in. The settings will return to standard.
Now you know how to enter UEFI or BIOS using different keyboard shortcuts. Next, in the BIOS you can configure the laptop for yourself and make the necessary changes.
