Getting into the BIOS on an ASRock motherboard is the first critical step for anyone looking to overclock, adjust boot order, or fine-tune system stability. The process is straightforward, but it differs slightly depending on whether you are in Windows or restarting from a cold boot. This guide provides the definitive method for all modern ASRock boards, including the latest B650 and Z790 models.
Preparing to Access the BIOS
Before you press any buttons, ensure your system is ready. You should save any open work in Windows, as the restart will interrupt active processes. If you are troubleshooting a system that fails to boot, you may need to use a USB keyboard, as some legacy BIOS setups do not recognize newer wireless peripherals reliably.
Method 1: Using the Windows Restart Menu (Fastest)
The easiest way to enter the ASRock BIOS is through the Windows settings menu. This method works on Windows 10 and Windows 11 and does not require you to time the boot sequence.
Step-by-Step Instructions
Press the Windows key + I to open Settings.
Navigate to System and then click on Recovery.
Under Advanced startup, click the Restart now button.
Your PC will restart to the Troubleshoot menu. Select Advanced options.
Choose UEFI Firmware Settings and click Restart.
Your computer will immediately load the BIOS interface, bypassing the need to hunt for the right key during the boot screen.
Method 2: The Traditional Hot Key Method
If you prefer the direct approach or need to access the BIOS in Safe Mode, the hot key method remains the standard. Every ASRock board uses the same key, but you must act quickly during the power-on self-test (POST).
Identifying the Correct Key
Look at the bottom left corner of your boot screen. As soon as you see the ASRock logo appear, press the designated key repeatedly. The two primary keys used are:
Timing is crucial. You usually have less than 5 seconds between the power-up fan noise and the Windows loading screen. Pressing the key too early might result in a keyboard error, while pressing it too late will boot into Windows. What to Do If It Doesn’t Work Sometimes, the standard methods fail due to fast boot settings or hardware issues. If pressing Delete or F2 does nothing, you likely need to disable Fast Boot in Windows first. This setting prevents the motherboard from posting early, which blocks the BIOS access.
What to Do If It Doesn’t Work
Another scenario is a failed boot device. If your hard drive is not detected, the system may halt the boot process before giving you a window to enter the BIOS. In this case, disconnecting non-essential drives (like extra SSDs) can help the POST complete successfully.
Navigating the ASRock BIOS Interface
Once inside, you will encounter the ASRock BIOS, which is usually split into two modes: Basic and Advanced. For overclocking and hardware monitoring, you must switch to Advanced Mode. Look for a button or tab labeled "Advanced" or "AI Tweaker."
The layout is generally intuitive, with categories listed on the right side. Be cautious when changing settings like CPU Voltage or DRAM Frequency, as incorrect values can cause system instability. Use the Load Optimized Defaults option if you ever need to reset changes quickly.
