I have Windows 8.1 as main OS in UEFI environment, I wanted to have another Windows 8.1 as a VHDX (native boot).

I used EasyBCD to add entry for the VHDX but, it didn't boot the VHDX and the boot menu was without GUI (EasyBCD don't support UEFI).

I tried using BCDEdit Command-Line and added VHDX boot successfully with GUI but I noticed that, my Windows 8.1 load first then, it gives me the boot menu meaning when I chose Windows 8.1 it gives me the longing screen IMMEDIATELY and when I chose VHDX it reboots and load the VHDX so i lose my "fast boot" to my main win8.1 with a start-up time of a few seconds .

What I need is to go straight to VHDX without booting the main Windows 8.1. How can I do that?

here is my BCDEdit output:

I moved it for you to the Windows 8.1 Installation forum.

Using BCDEdit you can change the Default operating system to your VHDX installed system and you can change the Time-Out value to 0 to boot the default entry without any prompt to boot the other operating systems in the BCD. Both options are outlined in the guide here on TechNet.
