Solved Convert Physical Disk to Windows to Go by VHD, Boot Error

Hey guys, I'm stuck in this dilemma and I would appreciate any help that would come.
So here's the thing,

1. I have Windows 10 Pro, activated thanks to my activated windows 8.1 pro which I just updated. basically buying a new Win10 cd key is a no-go for me since Microsoft offers a free upgrade.

2. I tried to do a clean install of windows 8.1 on a vhd in a USB. then from my Windows 8.1 to go, I tried to upgrade it to Windows 10 and got the following error:
a.) Windows cannot be installed in a Virtual Disk.
b.) Windows cannot be installed in a Windows to Go Drive.
So it seems that the only way to go is to convert my physical disk to a vhd and turn it into windows to go which I did using the diskpart procedure I fished out of the internet.

Create vdisk file=D:\Win2Go.vhd maximum=59000 I was going to install it in a 64 GB Flashdrive
Select vdisk file=D:\Win2Go
attach vdisk
detail vdisk
convert mbr
create partition primary1
format fs=ntfs label='Win2Go" quick
Assign letter=L

And so I have a 64GB blank VHD. Now Using AOMEI Partition Assistant, I copied my entire C: Drive partition to the Virtual Disk. then transferred my VHD to my 64GB Flashdrive.
then I created boot entries for my Flashdrive using BCDBOOT.

L:\>Windows\System32> BCDBOOT.EXE L:\Windows /s E: E: is my Flashdrive drive letter
and it says that boot files have been updated.

PROBLEM: When I boot from the Flasdrive, Windows Boot Loader is seen (the one with the windows logo and circling little circles XD) but then I always get the "INACCESSIBLE BOOT DEVICE" error!

I tried updating the boot files of the VHD itself using BCDBOOT. I also tried to fixMBR, fixboot and rebuildbcd...
Error still exists. What am I doing wrong? Sorry for the lengthy details, I'm still trying this stuff out :) thanks in advanced for the reply.

Well with a little bit more of nosing around, I found this great program that lets me convert my physical machine into a Windows-to-go drive. Its WinToUSB. :)
