Booting WDS Capture image on VM Gen2

Have problem booting capture image, created by Microsoft WDS management console. I have functional boot image (boot.wim) taken from WinServer 2012 R2 iso. This image works fine on Hyper-V Gen2 VM. But when I create capture image from working image, I am unable to boot and start the capture image on that same VM.

I have already made well-known fix of well-known MS bug (see this) - Status: 0xc000000f durring boot. I dont get this error anymore. But have another one:

After the capture image is successfuly downloaded from WDS server (progress bar), it tries to start the image (Hyper-V logo and spinner) for a while, but than I got blank black screen.
