Knowing how to access the BIOS\/UEFI is an essential skill for every user, from reinstalling the operating system and troubleshooting to optimizing computer performance. This article will provide detailed instructions, common keyboard shortcuts, and troubleshooting solutions if you encounter difficulties accessing this critical configuration environment.<\/p>\n<h2>What Are BIOS and UEFI? Why Are They Important, and When Do You Need to Access Them?<\/h2>\n<p>Before delving into access methods, it is important to understand what BIOS and UEFI are, as well as their roles in computer operation. Both are low-level software programs stored on a special memory chip on the motherboard, responsible for initializing the hardware and handing control over to the operating system when the computer is turned on.<\/p>\n<h3>BIOS (Basic Input\/Output System)<\/h3>\n<p>BIOS is a traditional firmware program that originated in the 1980s. It is the basic input\/output system that performs the initial boot-up tasks (POST \u2013 Power-On Self-Test) to check hardware components such as the CPU, RAM, graphics card, hard drive, etc. After a successful check, the BIOS searches for and boots the operating system from the specified storage device.<\/p>\n<p>Although it is now obsolete, the BIOS\u2019s role in laying the groundwork for the operating system remains undeniable in the history of computer development.<\/p>\n<figure class=\"ainr-source-image\"><img decoding=\"async\" title=\"Basic BIOS Interface\" src=\"https:\/\/xuanthuy.net\/wp-content\/uploads\/2026\/09\/giao-dien-bios-co-ban.webp\" alt=\"H\u00ecnh \u1ea3nh minh h\u1ecda giao di\u1ec7n BIOS tr\u00ean m\u00e0n h\u00ecnh m\u00e1y t\u00ednh\" data-attachment-id=\"10378\" \/><figcaption>BIOS (Basic Input\/Output System) is important software built into the motherboard.<\/figcaption><\/figure>\n<h3>UEFI (Unified Extensible Firmware Interface)<\/h3>\n<p>UEFI is a more modern firmware interface, developed by Intel in the late 1990s under the name EFI (Extensible Firmware Interface) to address the limitations of traditional BIOS. By 2005, its development and standardization were handed over to the UEFI Forum. Most computers manufactured after 2010 have switched to using UEFI instead of BIOS.<\/p>\n<p>UEFI offers many significant improvements, including support for larger-capacity hard drives, a more user-friendly graphical interface, and enhanced security features. It serves a similar purpose to the BIOS but with more advanced technology, ensuring a faster and more secure boot process.<\/p>\n<h3>When do you need to access the BIOS\/UEFI?<\/h3>\n<p>Users often need to access the BIOS\/UEFI to perform the following important tasks:<\/p>\n<ul>\n<li><strong>Changing the Boot Order:<\/strong> This is the most common reason, usually to reinstall the operating system from a USB drive or DVD, or to boot from a different drive.<\/li>\n<li><strong>Enable\/Disable Virtualization Technology:<\/strong> Features such as Intel VT-x or AMD-V are required to run virtual machines or emulators.<\/li>\n<li><strong>Configure peripheral or integrated devices:<\/strong> Enable or disable network cards, audio, USB ports, or other devices on the motherboard.<\/li>\n<li><strong>Setting a BIOS\/UEFI Password:<\/strong> Enhance security by requiring a password to access firmware settings or even to boot the computer.<\/li>\n<li><strong>CPU\/RAM Overclocking:<\/strong> On high-end motherboards, users can adjust settings to boost hardware performance.<\/li>\n<li><strong>Check basic hardware information or system temperature:<\/strong> View specifications for the CPU, RAM, and hard drive, or monitor the operating temperatures of the components.<\/li>\n<li><strong>Troubleshooting startup issues:<\/strong> When your computer cannot boot into Windows, checking the settings in the BIOS\/UEFI can help diagnose the problem.<\/li>\n<\/ul>\n<h2>BIOS vs. UEFI: The Key Differences<\/h2>\n<p>Although both serve to initialize the system, BIOS and UEFI represent two different generations of firmware technology with significant differences in capabilities and performance.<\/p>\n<ul>\n<li><strong>History and Architecture:<\/strong>\n<ul>\n<li><strong>BIOS:<\/strong> First introduced in the 1980s, BIOS is an older form of firmware that operates in 16-bit mode and can access only 1 MB of memory during the boot process.<\/li>\n<li><strong>UEFI:<\/strong> Developed in the late 1990s by Intel and standardized by the UEFI Forum since 2005, UEFI is a more modern firmware interface that supports both 32-bit and 64-bit modes, allowing access to more memory and enabling the execution of more complex tasks during the boot process.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Hard drive and partition support:<\/strong>\n<ul>\n<li><strong>BIOS:<\/strong> Due to the limitations of the MBR (Master Boot Record) partitioning standard, it supports only hard drives with a maximum capacity of 2 TB and a maximum of 4 primary partitions.<\/li>\n<li><strong>UEFI:<\/strong> It uses the GPT (GUID Partition Table) standard, which allows booting from hard drives larger than 2 TB (up to 9.4 ZB) and supports a virtually unlimited number of partitions. This is particularly important for today\u2019s high-capacity hard drives.

Secure Boot is designed to prevent malware from loading during the boot process by allowing only boot software that is digitally signed by trusted providers. This is a mandatory requirement for Windows 11.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Start-up speed:<\/strong> UEFI typically allows the system to boot significantly faster than traditional BIOS, thanks to its parallel processing capabilities and process optimization.<\/li>\n<\/ul>\n<h3>How can I tell if my computer is using BIOS or UEFI?<\/h3>\n<p>To check whether your computer is using traditional (Legacy) BIOS mode or UEFI, follow these steps in Windows:<\/p>\n<ol>\n<li>Press the Windows + R key combination to open the Run dialog box.<\/li>\n<li>Type \"msinfo32\" and press Enter to open the System Information window.<\/li>\n<li>In the System Information window, look for the line <strong>\u201cBIOS Mode\u201d<\/strong>.<\/li>\n<li>If displayed <strong>\u201cLegacy\u201d<\/strong>, your computer is using a traditional BIOS. If the following is displayed <strong>\u201cUEFI\u201d<\/strong>, your computer is using UEFI.<\/li>\n<\/ol>\n<h2>How to Enter BIOS\/UEFI Using Keyboard Shortcuts on PCs and Laptops<\/h2>\n<p>The most common and quickest way to access the BIOS\/UEFI is to use special shortcut keys as soon as the computer starts up. These keys usually need to be pressed repeatedly or held down for a few seconds immediately after you turn on the computer.<\/p>\n<h3>Common General Shortcuts<\/h3>\n<p>The following keyboard shortcuts are commonly used on many different computer models and motherboards:<\/p>\n<ul>\n<li>DEL (Delete)<\/li>\n<li>F2<\/li>\n<li>F10<\/li>\n<li>F12<\/li>\n<li>ESC<\/li>\n<\/ul>\n<figure class=\"ainr-source-image\"><img decoding=\"async\" title=\"Press the ESC key to enter the Boot menu\" src=\"https:\/\/xuanthuy.net\/wp-content\/uploads\/2026\/09\/nhan-phim-esc-de-vao-menu-boot.webp\" alt=\"M\u00e0n h\u00ecnh m\u00e1y t\u00ednh hi\u1ec3n th\u1ecb th\u00f4ng b\u00e1o nh\u1ea5n ESC \u0111\u1ec3 v\u00e0o menu Boot\" data-attachment-id=\"10379\" \/><figcaption>Start the BIOS setup process by pressing the ESC key as soon as the computer starts up.<\/figcaption><\/figure>\n<figure class=\"ainr-source-image\"><img decoding=\"async\" title=\"Press F10 to access the BIOS from the Boot Menu\" src=\"https:\/\/xuanthuy.net\/wp-content\/uploads\/2026\/09\/chon-f10-de-truy-cap-bios-tu-boot-menu.webp\" alt=\"M\u00e0n h\u00ecnh menu Boot v\u1edbi c\u00e1c t\u00f9y ch\u1ecdn v\u00e0 h\u01b0\u1edbng d\u1eabn nh\u1ea5n F10 \u0111\u1ec3 v\u00e0o BIOS\" data-attachment-id=\"10380\" \/><figcaption>From the Boot menu, press F10 to proceed to the BIOS settings.<\/figcaption><\/figure>\n<figure class=\"ainr-source-image\"><img decoding=\"async\" title=\"Select the BOOT and Recovery menu in Windows 7\" src=\"https:\/\/xuanthuy.net\/wp-content\/uploads\/2026\/09\/chon-menu-boot-va-recovery-tren-windows-7.webp\" alt=\"M\u00e0n h\u00ecnh menu BOOT ho\u1eb7c Recovery tr\u00ean Windows 7\" data-attachment-id=\"10389\" \/><figcaption>Select the BOOT menu, then select Recovery and restart the computer.<\/figcaption><\/figure>\n<figure class=\"ainr-source-image\"><img decoding=\"async\" title=\"BIOS Shortcut Keys by Motherboard\" src=\"https:\/\/xuanthuy.net\/wp-content\/uploads\/2026\/09\/cac-phim-tat-vao-bios-theo-mainboard.webp\" alt=\"B\u1ea3ng li\u1ec7t k\u00ea c\u00e1c ph\u00edm t\u1eaft \u0111\u1ec3 truy c\u1eadp BIOS tr\u00ean c\u00e1c lo\u1ea1i Mainboard kh\u00e1c nhau\" data-attachment-id=\"10391\" \/><figcaption>Each type of motherboard may have its own BIOS shortcut key, typically DEL, F2, or F1.<\/figcaption><\/figure>\n<h3>BIOS\/UEFI Access Shortcut Keys by Motherboard Manufacturer<\/h3>\n<p>For desktop computers (PCs) that use different types of motherboards, the keyboard shortcuts may vary depending on the manufacturer:<\/p>\n<ul>\n<li><strong>ASUS:<\/strong> DEL, F2, or F10<\/li>\n<li><strong>Gigabyte:<\/strong> DEL<\/li>\n<li><strong>MSI (Micro-Star):<\/strong> DEL<\/li>\n<li><strong>ASRock:<\/strong> F2 or DEL<\/li>\n<li><strong>Intel:<\/strong> F2<\/li>\n<li><strong>Foxconn:<\/strong> DEL<\/li>\n<li><strong>ECS Elitegroup:<\/strong> DEL or F1<\/li>\n<li><strong>Acer:<\/strong> F2 or DEL<\/li>\n<li><strong>HP (select models):<\/strong> F10 or ESC, then F10<\/li>\n<li><strong>Dell (select models):<\/strong> F2<\/li>\n<li><strong>Lenovo (select models):<\/strong> F1 or F2<\/li>\n<li><strong>Biostar:<\/strong> DEL<\/li>\n<li><strong>EVGA:<\/strong> DEL<\/li>\n<li><strong>Fujitsu:<\/strong> F2 (or F12 to enter the Boot Menu, then select BIOS Setup)<\/li>\n<li><strong>Supermicro:<\/strong> DEL<\/li>\n<li><strong>ZOTAC:<\/strong> DEL<\/li>\n<\/ul>\n<h3>BIOS\/UEFI Access Shortcut Keys by Laptop Model<\/h3>\n<p>Each laptop brand typically has one or more unique keyboard shortcuts.

This method is particularly useful when traditional keyboard shortcuts don\u2019t work or when you want to access UEFI settings more securely.<\/p>\n<h3>The Impact of the Fast Startup Feature in Windows<\/h3>\n<p>One important factor to note is the \u201cFast Startup\u201d feature\u2014also known as Hybrid Shutdown\u2014in Windows 10 and Windows 11. This feature helps the computer boot up faster after shutting down by saving the kernel state to a hibernation file. However, this may prevent you from accessing the BIOS\/UEFI using the traditional hotkey, as the system does not actually shut down completely but remains in a partial hibernation state.<\/p>\n<p>To ensure you can access the BIOS\/UEFI using a keyboard shortcut or through Advanced Startup Options, you should:<\/p>\n<ul>\n<li>Select \u201cRestart\u201d instead of \u201cShut down\u201d when you want to enter the BIOS\/UEFI.<\/li>\n<li>Alternatively, turn off the Fast Startup feature in Windows power settings:\n<ol>\n<li>Open the Control Panel and select \u201cPower Options.\u201d.<\/li>\n<li>Select \u201cChoose what the power buttons do.\u201d.<\/li>\n<li>Click \u201cChange settings that are currently unavailable.\u201d.<\/li>\n<li>Uncheck the \u201cTurn on fast startup (recommended)\u201d box.<\/li>\n<li>Save changes.<\/li>\n<\/ol>\n<\/li>\n<\/ul>\n<p>Managing startup applications can also affect system performance.

To enter the BIOS directly, pressing the shortcut key immediately upon startup is the standard and most effective method.<\/p>\n<h2>Troubleshooting: What to Do When You Can't Access the BIOS\/UEFI?<\/h2>\n<p>Sometimes, accessing the BIOS\/UEFI can be difficult. Here are some troubleshooting steps you can try:<\/p>\n<ul>\n<li><strong>Double-check the shortcut keys and when to press them:<\/strong> Make sure you're using the correct keyboard shortcut for your computer model and press it as soon as the computer powers on, before the Windows logo appears. Try pressing it repeatedly and quickly instead of just once.<\/li>\n<li><strong>Disable the Windows Fast Startup feature:<\/strong> As explained above, Fast Startup may prevent you from accessing the BIOS\/UEFI using a keyboard shortcut. Turn off this feature in Windows power settings, or select \u201cRestart\u201d instead of \u201cShut down\u201d when you want to enter the BIOS\/UEFI.<\/li>\n<li><strong>Try using a different keyboard:<\/strong> If you are using a wireless keyboard or a keyboard that is malfunctioning, try connecting a standard wired keyboard to a USB port to rule out the possibility of a keyboard-related issue. Sometimes, wireless keyboards may not initialize in time during the POST phase.<\/li>\n<li><strong>Reset the BIOS\/UEFI to its default settings:<\/strong> If you've changed the settings in the BIOS\/UEFI and are experiencing issues, resetting them to their default values may help resolve the problem.\n<ul>\n<li><strong>In the BIOS\/UEFI interface:<\/strong> Look for the option \u201cLoad Setup Defaults,\u201d \u201cLoad Optimized Defaults,\u201d or something similar. After selecting it, save the changes and exit.<\/li>\n<li><strong>Remove the CMOS battery (for PCs):<\/strong> For desktop computers, you can shut down the computer, disconnect the power, open the case, and remove the small CMOS battery on the motherboard for about 5\u201310 minutes. This will clear all BIOS\/UEFI settings and restore them to their defaults. Be careful when performing this procedure.<\/li>\n<li><strong>Using the CMOS reset jumper:<\/strong> Some motherboards have a jumper (pin) for resetting the CMOS. Refer to your motherboard\u2019s manual to find its location and learn how to use it.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Update the BIOS\/UEFI (only when necessary, and proceed with caution):<\/strong> A firmware update can resolve compatibility issues or improve performance. However, this is a high-risk process; if interrupted or performed incorrectly, it can permanently damage the motherboard (brick it). Therefore, you should only update when absolutely necessary, follow clear instructions from the manufacturer, and ensure a stable power supply.<\/li>\n<li><strong>Check the keyboard\/USB port connection:<\/strong> Make sure the keyboard is securely plugged into the USB port.

In this case, contact the warranty center or a professional technician for assistance.<\/p>\n<h2>Important BIOS\/UEFI Features You Should Know<\/h2>\n<p>Once you have successfully accessed the BIOS\/UEFI, you will see a range of system configuration options. Below are some important features that users often need to adjust:<\/p>\n<ul>\n<li><strong>Boot Order:<\/strong> These settings allow you to specify which device (hard drive, USB, DVD, network) the computer will attempt to boot the operating system from first. Changing the boot order is necessary when you want to install a new operating system from a USB drive or DVD, or boot into a repair environment. To create a Windows installation USB drive, you can refer to <a href=\"https:\/\/xuanthuy.net\/en\/huong-dan-tao-usb-cai-windows-bang-rufus\" data-ainr-post-id=\"10261\" >Guide to Creating a Windows Installation USB Drive Using Rufus<\/a> or <a href=\"https:\/\/xuanthuy.net\/en\/huong-dan-cai-dat-windows-winnt-setup-uefi-gpt\" data-ainr-post-id=\"10287\" >Install Windows 10\/11 using the standard WinNT Setup for UEFI\/GPT<\/a>.<\/li>\n<li><strong>Virtualization Technology:<\/strong> Features such as Intel VT-x or AMD-V allow you to run virtual machines efficiently on your computer. If you use virtualization software such as VMware or VirtualBox, you need to enable this feature in the BIOS\/UEFI.<\/li>\n<li><strong>Secure Boot:<\/strong> As a UEFI security feature, Secure Boot helps prevent malware from interfering with the boot process by allowing only software digitally signed by trusted providers to be loaded. Secure Boot is a mandatory requirement for installing and running Windows 11. You can learn more about <a href=\"https:\/\/xuanthuy.net\/en\/chia-o-cung-mbr-gpt-legacy-uefi\" data-ainr-post-id=\"10270\" >Secure Boot<\/a> in the context of hard drive partitioning.<\/li>\n<li><strong>Setting a BIOS\/UEFI Password:<\/strong> You can set a password to protect your BIOS\/UEFI settings from unauthorized access. Some systems also allow you to set a boot password, which requires you to enter the password before the operating system begins to load.<\/li>\n<li><strong>Hardware Monitoring:<\/strong> Most BIOS\/UEFI interfaces include a section that displays information about CPU temperature, fan speed, voltage, and other system parameters, allowing you to monitor your computer's operating status.<\/li>\n<li><strong>Peripheral\/Integrated Device Configuration:<\/strong> Here, you can enable or disable USB ports, built-in network cards, sound cards, or storage controllers (for example, switch between AHCI and RAID modes for hard drives).<\/li>\n<\/ul>\n<p>Understanding these features will help you manage and optimize your computer more effectively. However, always exercise caution when changing any settings in the BIOS\/UEFI, as incorrect changes can cause system errors.<\/p>\n<h2>Conclusion<\/h2>\n<p>Mastering how to access the BIOS\/UEFI is a basic yet extremely important skill for every computer user. Whether you need to change the boot order, enable virtualization, or troubleshoot issues, understanding the methods and shortcut keys will help you take control of your system. Always consult the manufacturer\u2019s documentation and exercise caution when making changes in the BIOS\/UEFI environment to ensure your computer operates stably and safely.<\/p>\n<h2 class=\"faq-tieu-de\">Frequently Asked Questions About Accessing the BIOS and UEFI<\/h2>\n<div class=\"faq\">\n<details open=\"\">\n<summary>How can I tell if my computer is using BIOS or UEFI?<\/summary>\n<p>You can check this by pressing the Windows + R key combination, typing \u201cmsinfo32,\u201d and pressing Enter. In the System Information window, look for the \u201cBIOS Mode\u201d line. If it says \u201cLegacy,\u201d your computer is using traditional BIOS. If it says \u201cUEFI,\u201d your computer is using UEFI.<\/p>\n<\/details>\n<details>\n<summary>Can I access the BIOS\/UEFI if my keyboard is broken?<\/summary>\n<p>If the keyboard is completely broken, it is impossible to enter the BIOS\/UEFI using a keyboard shortcut. In this case, you\u2019ll need to replace it or borrow another keyboard (preferably a wired one) to gain access. For Windows 10\/11, you can still try the Advanced Startup Options method if the operating system is still functioning, but you\u2019ll still need a keyboard to navigate through that menu.<\/p>\n<\/details>\n<details>\n<summary>Is there any software tool that allows you to access the BIOS\/UEFI without using a hotkey?<\/summary>\n<p>For modern computers running Windows 10 or Windows 11, you can access the UEFI settings through the operating system\u2019s Advanced Startup Options, as described in the article. This is a software-based method that does not require pressing a hotkey immediately upon startup.<\/p>\n<\/details>\n<details>\n<summary>Is it safe to update the BIOS\/UEFI?<\/summary>\n<p>Updating the BIOS\/UEFI can offer benefits in terms of performance, compatibility, and security, but it is a high-risk process. If the process is interrupted (e.g., a power outage) or performed incorrectly, it can permanently damage the motherboard. Therefore, you should only update when absolutely necessary and always strictly follow the manufacturer\u2019s instructions.<\/p>\n<\/details>\n<details>\n<summary>Why can't I access the BIOS\/UEFI even though I pressed the correct shortcut key?<\/summary>\n<p>There are several possible reasons, including pressing the shortcut keys too slowly or at the wrong time, Windows\u201c \u201dFast Startup\u201d feature being enabled, a faulty keyboard or one that didn\u2019t initialize in time (especially a wireless keyboard), or a hardware issue. Try turning off Fast Startup, using a wired keyboard, and making sure you press the key continuously as soon as the computer powers on.<\/p>\n<\/details>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Trong th\u1ebf gi\u1edbi m\u00e1y t\u00ednh hi\u1ec7n \u0111\u1ea1i, BIOS (Basic Input\/Output System) v\u00e0 UEFI (Unified Extensible Firmware Interface) l\u00e0 hai giao di\u1ec7n ph\u1ea7n s\u1ee5n (firmware) \u0111\u00f3ng vai tr\u00f2 n\u1ec1n t\u1ea3ng, qu\u1ea3n l\u00fd qu\u00e1 tr\u00ecnh kh\u1edfi \u0111\u1ed9ng v\u00e0 t\u01b0\u01a1ng t\u00e1c gi\u1eefa h\u1ec7 \u0111i\u1ec1u h\u00e0nh v\u1edbi ph\u1ea7n c\u1ee9ng.
