How to Open BIOS on Windows 11 (3 Methods That Actually Work)
The most reliable way to open BIOS on Windows 11 is through Settings > System > Recovery > Advanced startup. Click Restart now, then choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart. Your PC reboots directly into BIOS without you needing to time a keypress. This works on every manufacturer’s hardware, including Dell, HP, Lenovo, ASUS, and Microsoft Surface.
The old advice, tap F2 or Delete at startup, fails more often than it should on modern machines. A fast NVMe drive can bring Windows 11 to the login screen in 4 to 6 seconds, which leaves you almost no window to hit that boot key. If you have ever tried tapping a key repeatedly only to end up back in Windows, this guide will save you a trip down that rabbit hole.
By the end, you will know three verified methods for reaching BIOS, what each BIOS setting actually does, and why changing Secure Boot or TPM without your BitLocker recovery key is a fast path to a locked machine.
If you are troubleshooting a machine that is already slow to boot, it may be worth checking how to fix a slow laptop before changing BIOS settings, since many performance issues have a software fix that does not require BIOS access at all.
The Settings Route: Advanced Startup (Most Reliable)
This is the method Dell and Microsoft both recommend for Windows 11, and it is the one least likely to fail. No timing required.
- Open Settings (Win + I).
- Go to System, then scroll to Recovery.
- Under Recovery options, find Advanced startup and click Restart now.
- After the reboot, select Troubleshoot.
- Choose Advanced options.
- Select UEFI Firmware Settings.
- Click Restart. Your machine will boot straight into BIOS.
If you do not see UEFI Firmware Settings in that menu, your system partition may not be formatted as GPT, or the drive is not set to boot in UEFI mode. Older drives imaged from Windows 7 machines sometimes carry legacy MBR partitions, which puts UEFI options out of reach from within Windows.
One quick check: run msinfo32 from the Run dialog (Win + R). If BIOS Mode shows “UEFI,” the Settings route will work. If it shows “Legacy,” you will need the boot-key method instead.
Shift + Restart: The One-Click Shortcut
This is the fastest path if you are already at the desktop or the Windows login screen.
Hold Shift and click the power icon in the Start menu (or on the lock screen), then click Restart. Windows reboots into the same blue recovery environment described above. From there, the path is identical: Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
The Shift + Restart combination bypasses Fast Startup, which is the Windows 11 feature that hibernates the kernel rather than fully shutting down. A standard shutdown with Fast Startup enabled does not give you a clean boot window for BIOS access. Shift + Restart forces a full restart, making it the correct approach every time.
Boot Key Method: Still Works, but Timing Is Tight
Every motherboard or laptop has a designated key for BIOS access during Power-On Self-Test. On a Dell machine, that is usually F2. On ASUS, it is often Delete or F2. The table below lists the most common options.
| Brand | Boot-time key | Notes |
|---|---|---|
| Dell | F2 | F12 opens the one-time boot menu instead |
| HP | F10 | F9 for boot device selection; some models use Esc first |
| Lenovo | F1 or F2 | ThinkPads use F1; IdeaPad/Legion often use F2; some consumer models have a dedicated Novo button |
| ASUS | Delete or F2 | Desktops typically use Delete; laptops use F2 |
| Acer | F2 | Delete works on some older Acer desktop boards |
| MSI | Delete | MSI also uses Delete for both desktops and laptops |
| Microsoft Surface | Volume Up + Power | Hold Volume Up, then press and release Power; hold until UEFI appears |
The problem with the boot-key method on Windows 11 machines is Fast Startup combined with fast NVMe storage. SSDs like the Samsung 980 Pro can reach full read speeds of 7,000 MB/s, which means the machine can pass POST and hand control to the Windows bootloader faster than a human can register the manufacturer logo and press a key. The Settings route or Shift + Restart sidestep this entirely.
If the boot key is your only option (for example, the machine will not boot into Windows at all), disable Fast Startup first: Control Panel > Power Options > Choose what the power buttons do > uncheck Turn on fast startup. Then do a full shutdown and power on while tapping the key immediately.
A storage drive that shows unusual behavior at POST can also make timing worse. Before attributing slow boot behavior to BIOS settings, it is worth taking a moment to check your SSD health, since a drive with high reallocated sectors may be causing delays before Windows even loads.
What You Can Actually Change in BIOS/UEFI
Most users open BIOS once and never return. Here is what the settings you will encounter actually do, in plain terms.
Boot Order
Controls which device the machine tries to boot from first. If you are installing Windows from a USB drive, move the USB entry above the internal drive. If the machine skips your bootable USB entirely, this is almost always the cause. On UEFI systems, look for separate UEFI and Legacy entries for the same device; choose the UEFI version if your drive is GPT-partitioned.
Secure Boot
Secure Boot is a UEFI feature that verifies the digital signature of bootloaders before allowing them to run. Windows 11 requires it to be enabled. Disabling Secure Boot is sometimes necessary when installing certain Linux distributions or older operating systems that do not carry a Microsoft-signed bootloader.
Changing Secure Boot state can trigger a BitLocker recovery key prompt on the next boot if BitLocker is active on your drive. Before you touch this setting, retrieve your recovery key from your Microsoft account at aka.ms/myrecoverykey. Without it, you will be locked out of your own data.
TPM (Trusted Platform Module)
TPM 2.0 is the other Windows 11 requirement. It handles cryptographic operations that underpin BitLocker, Windows Hello, and Credential Guard. On Intel platforms this is listed as PTT (Platform Trust Technology); on AMD it appears as fTPM. Disabling it will also trigger the BitLocker recovery key prompt, for the same reason. Do not disable TPM unless you have a specific and well-understood reason.
Virtualization (VT-x / AMD-V)
Intel calls it VT-x; AMD calls it AMD-V. Both refer to hardware-assisted virtualization, which allows software like VMware Workstation, VirtualBox, Hyper-V, or Windows Subsystem for Linux 2 to run efficiently. On most current machines this is enabled by default, but it is disabled on some enterprise images for security policy reasons. If your hypervisor reports that virtualization is unavailable, BIOS is the first place to check.
XMP / EXPO (Memory Profiles)
XMP (Intel Extreme Memory Profile) and EXPO (AMD Extended Profiles for Overclocking) are pre-configured memory speed profiles stored on your RAM modules. Without enabling one of these, DDR5-6000 memory will run at DDR5-4800 or lower, which is the JEDEC default speed. You will find the option under an Advanced or Overclocking menu. Enable it, save, and exit. Your machine will reboot at the RAM’s rated speed.
The BitLocker Warning You Cannot Afford to Skip
Windows 11 Home and Pro both enable BitLocker device encryption automatically on machines that meet the hardware requirements, which most modern PCs do. This means your drive is likely encrypted right now, even if you never set a password.
Any change to the boot chain that BIOS monitors as a security signal, including toggling Secure Boot, disabling TPM, changing the boot order, or clearing the TPM, can cause Windows to request your BitLocker recovery key on the next startup. The recovery key is a 48-digit number stored in your Microsoft account. You can retrieve it from the official BitLocker recovery key page before you make any change.
Before you make any BIOS changes:
- Sign in at account.microsoft.com (or go directly to aka.ms/myrecoverykey).
- Find your device under Devices and locate the recovery key.
- Write it down or save it somewhere other than the encrypted machine itself.
If you enter BIOS, make a change, and the recovery key screen appears on reboot, this is normal behavior, not a sign of a failed system. Type the 48-digit key and Windows will unlock normally. The screenshot workflow for capturing that key screen is the same one described in our guide on how to take a screenshot on a Dell laptop, using a second device or phone to photograph it before entering the key.
How to Exit BIOS Without Breaking Anything
Every BIOS has two exit options:
- Save Changes and Exit (often F10): applies whatever you changed and reboots.
- Discard Changes and Exit (often Escape or a dedicated menu option): leaves everything exactly as it was and reboots.
If you entered BIOS to look around and changed nothing, use Discard Changes and Exit. Some BIOS versions ask if you want to save even if nothing changed; always confirm “No” in that case. A false save can sometimes reset a setting you did not intend to touch.
On Dell systems, the BIOS will also display a warning if you attempt to exit after changing something that affects the Secure Boot or TPM state, giving you a second chance to retrieve your recovery key before rebooting.
Most modern UEFI interfaces support mouse navigation, but if your pointer does not respond in BIOS (common on some desktop boards), use the arrow keys to move between options, Enter to select, and the function key shown on-screen to save or discard. F10 for Save and Exit is nearly universal across Dell, HP, Lenovo, and ASUS.
Open BIOS from Windows 11: Quick Reference
- Press Win + I to open Settings.
- Go to System, then select Recovery.
- Next to Advanced startup, click Restart now. Confirm if prompted.
- On the blue recovery screen, click Troubleshoot.
- Click Advanced options, then select UEFI Firmware Settings.
- Click Restart. Your machine boots directly into BIOS.
Total time from Settings to BIOS: under 90 seconds on any machine with a working Windows installation.
Frequently Asked Questions
What is the BIOS key for Windows 11?
There is no single key. The boot-time key depends on your manufacturer: Dell uses F2, HP uses F10, Lenovo uses F1 or F2, ASUS and Acer use F2, MSI uses Delete, and Microsoft Surface uses Volume Up held during power-on. Because fast NVMe drives compress the boot window to under 5 seconds, the Settings route is more reliable than trying to time a keypress.
Is UEFI the same as BIOS?
Not technically, but the terms are used interchangeably in practice. BIOS (Basic Input/Output System) is the older firmware standard; UEFI (Unified Extensible Firmware Interface) replaced it on virtually all hardware sold after 2012. UEFI supports larger drives, faster boot times, Secure Boot, and a graphical interface with mouse support. When someone says “open BIOS” on a modern machine, they mean the UEFI firmware settings screen.
Why can I not find UEFI Firmware Settings in Advanced options?
If UEFI Firmware Settings is missing from the Advanced options menu, the machine is likely booting in Legacy/CSM mode rather than UEFI mode. Run msinfo32 and check the BIOS Mode line. If it says Legacy, you will need to access BIOS via the manufacturer’s boot key during startup instead. Converting the drive from MBR to GPT (required for UEFI boot) is a separate process that involves disk repartitioning.
Will opening BIOS delete my files or reset Windows?
No. Simply opening BIOS and exiting without saving changes does nothing to your files or Windows installation. The risk only appears if you save changes that affect the boot chain (Secure Boot, TPM, boot order) without having your BitLocker recovery key ready. Your data is stored on the drive, not in BIOS, and BIOS settings do not touch drive contents.
How do I get back into Windows after accessing BIOS?
Select Save Changes and Exit or Discard Changes and Exit from the BIOS exit menu. The machine will reboot and load Windows normally. If Windows does not load and you see a recovery screen, it is likely a BitLocker prompt triggered by a BIOS change. Enter your 48-digit recovery key from aka.ms/myrecoverykey to proceed.
Next Steps After BIOS Access
BIOS access is often the first step in a broader hardware troubleshooting session. If you came here because your machine is running slowly or behaving unexpectedly, the next logical checks are drive health and thermal performance. Both can be diagnosed without any BIOS changes. The guides on how to check your SSD health and how to fix a slow laptop cover both in detail.
