Ref: https://community.spiceworks.com/topic/2329130-disk2vhd-created-vhdx-won-t-boot-system-is-uefi-and-vm-is-gen-2

Option one: Altaro

Download Altaro Physical Server backup.  Run a Backup.  Then using the same software run a "Restore to VM".  Takes 2x as long as below method but works great, and is free (for 30 days).

Option two: bcdedit

Run DISK2VHD on the source server then configure the VM as a Generation2 VM with the VHD attached and boot to a Windows Server ISO run the recovery console to access the command prompt

• diskpart

• sel disk 0

• list vol

• sel vol (number of the RAW volume should be around 99MB or 100MB)

• format fs=fat32 quick

• assign letter=A

• exit

• bcdboot C:\Windows /s A: /f UEFI

exit and reboot, the server will boot normally.
