Restore Verification Failed (code 2044)
Situation
An image-based backup plan (or any other plan with supported and enabled Restore Verification feature) terminates with the following warning: Restore Verification Failed. Restore Verification requires UEFI-compatible Hyper-V virtual machine. The installed Windows version does not support UEFI VMs

Cause
The cause of this warning is stated in the description: Restore Verification requires a UEFI-compatible Hyper-V virtual machine. This means you have a Windows Server 2012 operating system or any other with no UEFI virtual machine support.
Solution
If your backups strictly require Restore Verification, consider upgrading Windows to a version that supports UEFI Hyper-V virtual machines.
Otherwise, disable Restore Verification by editing the backup plan configuration.
