What causes the EFI Bootloader error?

Problems with the EFI Bootloader are rare and don’t happen often, but it’s important to identify what causes them so you can be prepared if they do occur.

Your computer is infected with malware – Computer viruses are usually the number one culprit of hardware problems. Download some antivirus software like ESET to clean up your computer. The MBR is corrupt – The master boot record may have gotten corrupted. You should scan the drive for errors, but if that doesn’t work, you may need to rebuild the MBR. The power supply is faulty – A PSU (power supply unit) not working properly can cause all sorts of problems. Check the hardware for any defects. You may need to replace the CMOS battery.

How can I fix the EFI Bootloader?

There are several ways to fix the EFI Bootloader on Windows 11, ranging from quick and easy solutions to slightly more complex ones.

The first thing that you should do is restart your computer. Performing this step will fix EFI Bootloader problems the majority of the time. If that doesn’t work, try using PC repair software like Restoro or Advanced SystemCare. These apps can solve a variety of errors to make sure your computer runs smoothly.
