Install Windows 11 in Hyper-V (VM) and use it in Native Boot (VHDX)

Will it work?

Only add: bcdboot K:\Windows on VHDX Image or?

The problem here is that in a VM it's running under the Hypervisor or other Virtual Software program. This means the Virtual machine will need a bootloader (on the virtual disk on an efi partition).

The usual way to do this is to boot into a Windows install disk / or other Winpe environment - FROM THE GUEST -- choose repair system and then in command mode enter diskpart, attach the vhdx file as a vdisk, this will then mount as a disk volume from which you can install the bootloader from the installed Windows build. You don't really want to mix builds -- unless there's specific reasons such as using a bootloader from the 23H2 builds.

So the actual Virtual disk created in the Hyper-V configuration settings for the VM needs to contain an EFI partition, the vhdx windows file and a bit left over.

I don't think (I don't know the definitive answer) it will work purely from the vhdx file -- macrium viboot has some mechanism for booting directly vhdx files but logically unless Ms have changed Hyper-V a lot I can't reason why this would work.

If anybody has been able to make it work under HYPER-V (running of course a Guest Windows system) I'd be very interested.

I will just use:

dism /get-wiminfo /wimfile:J:\sources\install.wim

dism /apply-image /imagefile:J:\sources\install.wim /index:1 /applydir:K:\

bcdboot K:\Windows

Hyper-V create own GPT Partition and i can't even Mount VHDX.

I think you have to attach the vhdx file in diskpart and then select disk , then select volume and create a volume letter for it.
