Windows PC stuck in boot loop after BIOS update

If your PC gets stuck in a boot loop after a BIOS update, the solutions provided in this article will help you. A BIOS update improves hardware compatibility and the system’s stability. However, some users encountered this issue after installing the latest BIOS update.

Windows PC is stuck in a boot loop after BIOS update

Use these fixes if your Windows PC is stuck in a boot loop after a BIOS update. Before proceeding, disconnect all peripherals and check if your PC boots into Windows.

1. Perform a hard reset
2. Test your RAM manually
3. Rebuild BCD
4. Disable the XMP Profile (if applicable)
5. Run Startup Repair
6. Reset your PC
7. Reinstall Windows

All these fixes are explained in detail below:

1] Perform a hard reset

Hard reset your computer by following these steps:

1. Press and hold the power button to turn off your computer.
2. Unplug the power cord. If you are a laptop user, disconnect its charger.
3. Remove the battery from your laptop. Skip this step if your laptop has a built-in battery or if you are a desktop user.
4. Press and hold the power button for 30 seconds.
5. Reinsert the battery and turn on your computer.

Now, check if the issue persists. We also suggest you clear CMOS. Turn off your computer and open its case. Now, remove the CMOS battery and wait for a few minutes. Reinsert the battery with the right polarity and turn on your computer.

2] Test your RAM manually

The problem may be associated with your RAM. If your system has more than one RAM stick, you can test them manually. Turn off your computer and open its case. Remove all the RAM sticks. Now, insert any one RAM stick and boot your computer. Similarly, test all RAM sticks individually.

3] Rebuild BCD

BCD is the Boot Configuration Data file that contains boot configuration parameters on how to start Windows. Boot issues occur when the BCD file is corrupted. In such a case, you can repair or rebuild the BCD file.

4] Disable the XMP Profile (if applicable)

If the XMP profile is active on your system, it might be causing this problem. Disable it and restart your system. If this works, you can enable the XMP profile again in BIOS. Enter your BIOS and look for the XMP profile setting to disable it.

The XMP profile is named as DOCP and EOCP on different motherboards. For example, in some ASUS motherboards, this profile is named DOCP.

5] Run Startup Repair

Startup Repair is a Windows Recovery Tool that fixes startup issues. You can launch it in Windows Recovery Environment. Since your system is stuck in a boot loop, you cannot use Windows 11 Settings to boot into Windows Recovery Environment. In this case, you have to disturb the Windows normal startup process. Follow these steps:

1. Press and hold the power key to force shut down your computer.
2. Press the power key to turn on your computer.
3. When the Windows logo or manufacturer’s logo appears on the screen, immediately press and hold the power key to turn off the computer.

Repeat the above steps until you see the Preparing automatic repair screen. Now, you are in Windows Recovery Environment. Select Troubleshoot > Advanced Options > Startup Repair. Do not turn off your computer until the Startup Repair completes.

6] Reset your PC

If the Startup Repair does not fix the problem, you can reset your PC. Again, you have to boot into Windows Recovery Environment to reset your PC. While resetting your PC, select the Keep my files option, as this option will reset your PC without deleting your files.

Once you enter Windows Recovery Environment, select Troubleshoot > Reset this PC. This process will take time. Do not turn off your computer until the reset is finished.

7] Reinstall Windows

If none of these solutions help, the last resort is to reinstall Windows by using a bootable USB flash drive with Windows installation media. Unfortunately, this method will erase your data from the C drive. For this, you need a working computer. Open a web browser on a working computer and download the Windows 11 ISO file. Now, use a third-party tool, like Rufus, to create a bootable USB flash drive with Windows 11 installation media.

You can also use Microsoft’s Media Creation Tool to download a Windows ISO and create the installation media. Now, remove the USB flash drive from the working computer and insert it into your computer. Enter the BIOS by pressing the required BIOS key and change the boot order to USB flash drive. Now, boot with the USB flash drive and install Windows 11.

I hope this helps.
