Windows 8 and windows8 VHDX UEFI dualboot

Question

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:

Hi,
How to change the boot sequence for the next reboot:
At the command prompt, type:
bcdedit /bootsequence {ID} {ID} {ID} …
ID: Specifies the GUID(s) that make up the boot sequence for the next restart. After this one-time boot it will revert back to the default boot order.
Examples
The following command sets the specified operating system as the default for the next restart. After that restart, it will be reset to DISPLAYORDER.
bcdedit /bootsequence {cbd971bf-b7b8-4885-951a-fa03044f5d71}
The following command sets two operating system entries and the
legacy Windows loader (Ntldr) in the boot manager one-time boot sequence:
bcdedit /bootsequnce {802d5e32-0784-11da-bd33-000476eba25f}
{cbd971bf-b7b8-4885-951a-fa03044f5d71} {legacy}
