Amoschb,   If you are using a 15th generation server then I would suggest getting it updated to current. As the latest update added the ability to see the Virtual  Disk descriptors in the UEFI boot sequence , as seen here. Unfortunately 14th generation and older systems do not have the option, so there is nothing to help differentiate between the two.    Let me know if this helps.
