Hi folks,

I had to install a DomU Windows 2008 server x64 SP2, to replace parts of the functionality of a physical server that suddenly died. I know it's old stuff, but this is needed in the meantime, until I get new servers.

After installing all the Windows updates (around 230), I downloaded and installed the signed Windows PV drivers ver. 8.2, starting with xenbus, and following up with xenif, xenvbd, xenvif, and xennet. After reboot of the DomU, Windows Boot Manager window popped up after a while, saying:

Windows failed to start. A recent hardware or software change blah, blah, blah...

In the lower part of the screen it says:

File: \Windows\system32\DRIVERS\xenbus.sys

Status: 0xc0000428

Info: Windows cannot verify the digital signature for this file.

Pressing Enter and booting with advanced options, I choose Disable Driver Signature Enforcement, and the OS boots normally.

I've tried to use the common tricks for unsigned, or test signed drivers, but that has got no effect whatsoever. I use the same signed drivers successfully with Windows 7, and Windows 10.

Anybody got an idea, how I can get it to boot without manual intervention each time?

Best regards,
