How To Upgrade Your ASRock BIOS Safely

February 11, 2026 4 minuti di lettura Updated: February 11, 2026

Updating the BIOS on your motherboard can be a nerve-wracking experience — kind of weird, but if done right, it can actually fix stubborn hardware issues or unlock new features. The thing is, if your system isn’t booting right, or hardware isn’t detected correctly, an out-of-date BIOS might be the culprit. Also, some new CPUs or hardware require the latest firmware, and BIOS updates sometimes include security patches or performance improvements. But hey, messing with BIOS isn’t something to take lightly; a corrupted update can pretty much brick your motherboard. So, it’s worth jumping in only when you’ve confirmed it’s needed, and you’ve got the proper files from the manufacturer.

In this guide, the focus is on ASRock motherboards, since they offer both the Instant Flash utility (which is straightforward and works from the BIOS itself) and UpdateCapsules (which can be done from Windows).The key is—make sure, first, that you actually need to update. On some setups, the BIOS version is fine, and running an update without a real reason might just cause trouble. Also, it’s crucial to keep the power stable during the process; a UPS is highly recommended. Download BIOS files only from official sources like the ASRock Support page. Third-party tools or shady sites could mess things up.

How to Fix BIOS Update on ASRock Motherboards

Check Your Current BIOS Version & Motherboard Model

This step helps determine whether you actually need to upgrade. If your BIOS is already recent and everything’s running smoothly, maybe skipping the update is safer. To find your current BIOS version:

  • Hit Win + R, then type msinfo32 and press Enter.
  • Look for BIOS Version/Date and BaseBoard Product (that’s your motherboard model) in the System Summary. For example, I’ve got a Z370M-ITX/ac and BIOS P1.50 from 2017. That’s kinda old now, considering BIOS updates often span years.

Check for BIOS Updates Online

Head over to the ASRock support page. Search for the exact motherboard model. Be careful—there might be a few versions or slightly different BIOSes for different SKUs. Find the one that matches your board (e.g., mini, gaming, pro).Expand the Support > BIOS section to see available updates, sorted by version number. Usually, the latest is on top. Read the description to see if the update mentions hardware compatibility fixes, security patches, or performance tweaks. Sometimes, updates are non-revertible, so flashing an older BIOS is a no-go afterwards.

On my setup, I prefer using Instant Flash when possible; it’s safe and inside the BIOS. Otherwise, for supported boards, the UpdateCapsule method is a good alternative — it basically does the job in Windows with minimal fuss.

Method 1: BIOS Flash Using Instant Flash

This is the simplest — and safest — way to update a BIOS on ASRock boards. It’s built into the BIOS itself, so you don’t have to mess around with Windows or download any extra tools. To do this, you’ll need a USB drive formatted as FAT32. It helps ensure compatibility.

  1. Plug in your USB drive and format it as FAT32. On Windows, right-click the drive in Explorer, choose Format, and pick FAT32 from the dropdown.
  2. Download the BIOS file ZIP from ASRock’s site. Extract it—you should end up with a ROM file, like P1.50.asus or similar. Move that ROM to the USB.
  3. Reboot your PC and enter BIOS by pressing Del or F2 during startup. Some boards let you press F6 to jump directly into Instant Flash, but no big deal—inside BIOS, look for the Tools menu and select Instant Flash.
  4. Let Instant Flash scan for the BIOS files on your USB. It should detect the ROM file you placed there. Pick the correct version and confirm. The flashing process will start — doesn’t take more than a few minutes. Do NOT turn off the PC or interrupt during this part.
  5. Once it’s done, you’ll be prompted to restart. Press OK, and upon reboot, head back into BIOS (press Del) to load defaults: go to the Exit menu and select Load UEFI Defaults. Then, save and exit. Your motherboard should now run the latest firmware.

Method 2: BIOS Update via UpdateCapsule in Windows

This method is kinda risky if your system isn’t stable, but on supported setups it’s pretty smooth — especially if you’re lazy (like many of us).It uses a tool called ASRock Instant Update or ASROCK Firmware Tools, depending on what’s preinstalled. The main advantage? You don’t need to reboot into BIOS — just run the update in Windows, and it handles the rest.

Because of course, Windows has to make things more complicated than necessary, right? Some older boards or OS versions might not support this, so check the compatibility first.

  1. Extract the BIOS ZIP file you downloaded earlier.
  2. Run the installer or the ASROCK Instant Update utility that comes with the package. When the program launches, it’ll probably ask you to accept some prompts.
  3. You might get a warning that the BIOS update will require a reboot and could risk your system if interrupted. Confirm and proceed.
  4. It’ll load the capsule into the system’s secure memory and then automatically reboot. During the reboot, the BIOS update takes place—kind of magical if it works right.
  5. After the system restarts, go into BIOS again (press Del) to load defaults: go to Exit > Load UEFI Defaults, then save and exit. Your BIOS should now be the latest version.

If these methods don’t work or you get errors, double-check that your motherboard supports the update method, and that you’re using the correct BIOS file for your exact model. Also, keeping a backup of current BIOS via tools like Winhance can save a headache if something gets borked.
