How start VHDX from a Win Boot Menu
(03-17-2016, 01:08 AM)lbosco76 Wrote: Hello,
I have a pc with win 8.1. From another pc I made a USB device with a VHDX-based Windows. I follow instruction "Booting both BIOS-based and UEFI-based computer" and create 2 partition, one FAT32 and one NTFS.

Now I want modify the boot Menu of win 8.1 to add an entry to boot from USB VHDX. The difficult is that in a new Entry of the Boot Menu I must insert the path of *.efi in \Windows\syste32\   directory. Obviusly if the operating system is into del VHDX, I haven't a Windows path.

Someone know if is possible and how, to invoke from a Windows Boot Menu the start of a Windows OS inside a VHDX?


1. Run command prompt (cmd.exe) as administrator, then run Diskpart at the command prompt.

2. Type the following commands to mount the vhd(x) file

In my case E:\ is my USB Hard Drive.
DISKPART> Select vdisk file=E:\WinToUSB.vhd (E: is the USB DRIVE, WinToUSB.vhd is the vhd(x) file want to boot)
DISKPART> Attach Vdisk

In my case F:\ is the mounted VHD file.

3. Run the following command to add an boot entry to Windows 8.1 boot menu
C:\Windows\System32> F:\Windows\System32\Bcdboot.exe F:\Windows (F: is the mounted VHD file)
