Debian won't boot after added to Windows AD

[dewoz90]

Yeah, debian won't boot after I added it to a windows AD (windows server 2012)

I used this method: http://www.alandmoore.com/blog/2015/05/ ... directory/
Joining the AD was successful.

What could be the problem?

When I start the VM, GRUB runs and after choosing the system's version (restore or normal boot) a black screen appears.

I tried removing quiet mode from GRUB boot, no errors..

What video card are you using?
