I am currently investigating the source for the ++++++ problem. I do not think that this problem roots back to my EFI and BIOS configuration. In my case, the PB3/DP4 installer boots absolutely flawless. I rather think that there must be some user error at some point.
Now the most interesting investigation I am actually carrying out with
@ICEVISION. He owns the identical mobo (ASUS X99-A II) and processor (i7-6950X) configuration, with identical BIOS settings and an identical EFI folder, but reports the same ++++++, which is simply impossible. His rig must boot flawless the DP4 installer like mine, but apparently does not because of unknown origin
I asked him to do the test described in
post #132 and post
post #142. If you want, you can participate in this test investigation with your ASUS X99 Deluxe II and provide your user feedback.
We have to find the knot, why some users are not able to boot the PB3/DP4 installer, although in my case and with my BIOS, hardware and software configuration everything just works flawless.
Cheers,
