bcdboot.exe failed with code 87!

[huberthk]

Hi,

On Azure Stack HCI 22H2 when deploying Hyper-V VM gen 2 with UEFI layout I get error "bcdboot.exe failed with code 87!".
It does not happen every time and on every system.
Any ideas as to why and how to troubleshoot?

Here's the (scrapped) transcript
