try these boot flags when booting the installer,

 

GraphicsEnabler=No SkipAtiGfx=Yes SkipNvidiaGfx=Yes SkipIntelGfx=Yes IGPEnabler=No 

 

Also could try setting your resolution in a boot flag like :

 

"Graphics Mode"="1920x1080x32"

 

Whatever the native resolution is.

The HD4000 in my Elitebook doesn't show up, it uses the ATI m5950  I used the probook installer and my graphics are working well on this machine, I realize it won't help the OP, but the HD4000 never showed up when trying the methods here always had no QE/CI until I went to the uefi clover method with probook installer. the following is the output from HWinfo32 for Graphics Adapter.
