No HDMI video at start of boot process

I have a DZ77SL-50K with a Core i5 3570K that has Intel HD Graphics 4000. The problem I have is that there is no video in the beginning of the boot process. I had to borrow a graphics card from an other machine to be able to access the BIOS settings and install the OS. Now the video turns on after the OS has been loaded. But I can't access BIOS settings or OS selection.
