Have now done a clean install of Server 2012 Standard again. All appeared to work fine, Windows rebooted and went through it's Configuring "Windows Features process", when complete it rebooted. Now fails to boot every-time with the error:
Error code: 0x0000005C
Parameters:
0x000... 110
0xFFF...D104C8
0x000...19
0xFFF...C0000001
Now just for testing I have turned off BIOS support for Virtualisation and now the server boots-up.
Are there any known problems with using 2012 Hyper-V on this board?
Is there any chance of a BIOS update to fix this?
