BTW, I was able to install the Windows Hyper-V 2019 on Dell poweredge R530. I just needed to disable secure boot. 
Hello We have PowerEdge R530 which I have been trying to install Windows Hyper-V Server 2019. I have updated the Bios to 2.16, iDRAC to 2.83.83.83. I have tried both Boot manager and Lifecycle Controller. Both method is able to boot to USB Drive and shows Windows Logo, then a dark blue background shows and nothing else. What am I missing? As I found r530 supports 2019 
Install Windows Hyper-V 2019 on R530?
