5 Solutions to Fix Winload.EFI Error

Windows can be a sophisticated operating system at times. It has a lot of things to take care of due to the constant installing/uninstalling of applications, changes in internal registries, modification in data due to scattering, amongst other things.

Sometimes, this complexity and the combination of misfortune can lead to errors and corruption of files.

This error is one of those instances where a critical file gets corrupted and hence, more drastic actions are required, and this BSOD shows up.

The errors codes that usually show up are 0xc0000225, 0xc00000e and 0xc0000001.

Reasons For the Error

The main reason this error greets you is that the file \windows\system32\winload.efi is missing or corrupted.

winload.efi is an essential file for booting up your PC. It is an executable file of the EFI environment that initiates the boot-up of your Windows PC. The boot configuration loads up winload.efi and starts up your PC.

The following cases are the most common reasons:

● Failure in Windows System Update

● If you have used a third-party tool to migrate your OS,

● Hard disk’s file system files are corrupted due to a virus attack or power cuts or due to disk write errors.

Solution #1 – Disable Secure Boot

One of the more straightforward solutions to this error is to simply go to your BIOS and disable Secure Boot.

Every hardware manufacturer has its own predefined way of entering BIOS. Usually, the BIOS can be entered by pressing the F8 or F2 key on the keyboard, but at the end of the day, it depends on your PC.

Since, winload.efi is a part of the EFI environment, in this case, we’re disabling it to use the legacy procedure which might solve our problem.

Solution #2 – Check the disk for errors and OS integrity

Usually, one of the common reasons PCs fail is due to disk errors where some things were stored in a manner not desired, due to power outage, virus attacks.

We can try and repair these disk errors by accessing the Command Prompt before even booting the system, the command prompt can be accessed using these instructions.

We can also use the SFC utility that scans our Windows installation for corruption or potentially faulty changes. If there are such changes, it’ll try and replace the file using the original data from a system backup.
