Resolve the Windows Server 2019 bug stopping it from booting on certain servers with UEFI enabled when the Hyper-V Role is installed.
There's a pretty big problem on some servers (at least two Dell PET Servers I've tried so far) that stops Server 2019 from booting/goes into a boot loop once the Hyper-V role is installed.
Seriously Microsoft??? Many of us wants to start upgrading to WS2019....
R510 has this issue when installed on UEFI as well.
Still not fixed with 2018-12 Cumulative Update for Windows Server 2019 for x64-based Systems (KB4483235) installed.
This issue does not happen with Windows Server vNext Preview Build 18298 so it's either fixed there or the bug is not on that branch.

Dell R710 with this problem
Same problem here. Dell R720 with Windows Server 2019 Datacenter with last update 2018-12. After enabling Hyper-V, the server enter in a reboot loop.
Agreed -- why this would even need a suggestion is beyond me, but... I've tried updating to the 2018-12 rollup, and it STILL bootloops once HyperV is installed, so they don't seem too interested in fixing a showstopper.
