Winload.efi Error 0xc0000225

The Winload.exe file is the Windows operating system boot loader (an Extensible Firmware Interface(EFI) file) to boot system correctly. In UEFI systems, it’s called winload.efi, and located at \Windows\System32\winload.efi or \Windows\System32\boot\winload.efi.

Sometimes, you might encounter other error codes associated with Winload.efi file, like error code 0xc000000e after clone Windows 10, winload.efi error code 0xc000000f, winload.efi 0xc0000428, etc. This article will help you to resolve these winload.efi missing problems with detailed steps.

The Causes to Winload.efi Missing after clone

The Winload.efi missing error is usually occurred after clone, after sysprep, after image or even after Windows update. There are some factors should be responsible for the Winload.efi file is missing after clone:

1. The incorrect registry key. The source disk and target disk owns different ID for volumes and drive letter, so you have to change the registry key after cloning.

2. Improper UEFI settings. The UEFI and Legacy mode requires different boot files and algorithms. So, make sure you set up correct settings for your destination disk.

3. The corrupted BCD files. Sometimes, cloning will damage the BCD store files, and then you will get this Winload.efi 0xc0000225 error message or other Winload.efi missing problems. Just repair BCD files first.
