Virtualbox 5 Windows Guest Extensions

[BarryHavenga]

I successfully installed and ran Windows 10 (including Guest additions) on all prerelease versions of Virtualbox 5 running on Kubuntu 15.04, 64 bit host. When I installed the released version however and then installed the Guest additions ISO I got the following error message when trying to reboot Windows:

The operating system could not be loaded because the digital signature of a file could not be verified.

File: \\Windows\system32\DRIVERS\VBoxGuest.sys Error Code: 0xc0000428

I made various attempts to get Windows to ignore the digital signature (or lack thereof) of drivers but without success.

Any Ideas?

Hi, I can confirm the issue – host Kubuntu 15.04, Virtualbox 5.0.0, guest Windows 10 from modern.ie, error 0xc0000428.
Pressing Enter or F8 both lead to the same error in a second.

So anyone know what's the solution ?

I can't boot and I have some data that needed on this machine !!

I try refresh but nothing happen, same boot message, and can't use safe mode even.

You can find some advices on bug #14263 (Nested Paging disabling).

If you want the data only, mount the image VDI file and get it directly.
