After reading the https://support.microsoft.com/da-dk/kb/3033929, it got me thinking.
Maybe there is something in the newer bioses that restrict some installations, that may try to access the hardware in some special way.
A computer here with Asus motherboard got that issue it can not install it.
An other computer here from Acer and HP pre builds do not have that issue and already have then installed.
Havent been able to test that out yet, but i know on some older computer they had a boot sector protection, so thats why it got me thinking in that direction.
As written on that page.
Issue 1 workaround
To work around that issue, you can either use Windows as the default boot loader or you can change your BIOS settings
to enable the Windows boot loader directly when you install this update.
So that bios setting can sure have some influence.
