MDT – Failure (5616) 31: Verify BCDBootEX

I was deploying a new Windows 10 installation on an old box via MDT the other day and it was failed.

A quick Google search tells me that this is something to do with UEFI boot. It makes sense since it’s an old box. So, I created another sequence that only formats and prepares the disk for BIOS legacy boot and also applied the hotfix that fixes the issues with BIOS type firmware. But no luck, the deployment still fails right after the OS installation phase.

Guess what, to be able to deploy a Windows 10 installation on an old computer that doesn’t have the UEFI boot option, I will have to prepare a USB bootable disk with the BIOS boot option and boot from it.

Once I boot from it, it went through without any further errors.
