BIOS Update Made Easy 😎

Find the Exact Model and Current Version

Everything in a BIOS update depends on two facts: the exact motherboard (or laptop) model, including its board revision, and the BIOS version currently installed. A file made for a different model — or even a different revision of the same model — is the most common way boards get bricked, so this check comes before any download.

In Windows, press Windows + R, type the command below and press Enter. In System Information, note down BaseBoard Product (your board model) and BIOS Version/Date (where you are starting from).

Save the BitLocker Recovery Key First

The TPM chip measures the firmware at every boot, and a BIOS update changes those measurements — so a PC with BitLocker or device encryption switched on can boot straight into a recovery-key screen after the update. Your data is not lost; the PC is simply asking for the 48-digit recovery key. The only real danger is not having that key saved somewhere you can reach it.

First check whether your system drive is encrypted at all. Open Command Prompt or Terminal as administrator and run:

manage-bde -status C:

If protection is on, display the recovery password and save it — on paper and on your phone, not only on this PC:

manage-bde -protectors -get C: -type RecoveryPassword

Suspend BitLocker Protection for the Update

With the key safely saved, suspend protection so the firmware change does not trigger the recovery screen at all. This command pauses protection for the next two reboots — long enough for the flash and the first boot afterwards — and then turns it back on by itself:

manage-bde -protectors -disable C: -RebootCount 2

Download the Exact BIOS File — From the Maker Only

Go to the motherboard or laptop maker's own support page for the exact model you noted in Step 1, and download the BIOS version you decided on. Read the release notes before downloading: some boards must be updated in steps, through an intermediate version first, and some updates cannot be rolled back afterwards.

Extract the zip if there is one, and copy the BIOS file to a USB stick formatted as FAT32 — most built-in flashers can only read FAT32.

Set Up Stable Power — and Do Not Interrupt

A power cut during the few minutes the flash is writing is the classic way boards die. On a desktop, run through a UPS if you have one and pick a calm time — not during a storm or a known outage window. On a laptop, plug in the charger and keep the battery charged; many laptop updaters refuse to start on battery alone, and that refusal is protecting you.

Close all programs, let Windows finish any pending update restarts first, and on a desktop plug the USB stick directly into a rear motherboard port.

Flash with the Built-In Flasher

Restart the PC and enter the BIOS/UEFI setup (the exact key is shown on the maker's splash screen at power-on). Open the BIOS's own built-in update utility, select the BIOS file from your FAT32 USB stick, double-check that the model and version it displays match the file you intended, and start the update.

Now leave the machine alone. The screen may go blank or restart more than once — that is normal during a flash. Wait until the PC boots back into the BIOS or Windows on its own before touching anything.

Restore Your Settings and Verify

An update often resets BIOS settings to defaults, so go back into the setup and restore what you had — memory profile (XMP/EXPO), boot order, fan settings — or simply confirm the defaults suit you. Then boot into Windows and run msinfo32 once more: the BIOS Version/Date line should now show the new version. Finally, confirm BitLocker protection has resumed on its own after the two reboots (Step 2's status command shows it), or turn it back on manually if it has not.
