Same issue here with UCSM 4.2(1f), B200M4, Pure array on FC and Windows 2k19.
Impossible to boot windows after complete uefi install. Error 0xc000007c, ntoskernel missing or corrupt. I tried to repair the boot with a custom iso (vic driver injected), no result. I also tried to run "sfc /scannow" on C: partition from WinPE but no corruption found.
Had to switch to legacy boot type. I'm in a lab environment so it's not a big deal.
