Convert VMWare Windows disk partitioning from MBR/BIOS to GPT/UEFI
Login into Windows, open a command prompt and type the following command.
MBR2GPT /convert /disk:0 /allowfullos
After change – shutdown the VM and change the Firmware type to UEFI before booting back up or it won’t boot.

Thank you for this information. I've got a couple VMs that are set to BIOS firmware that need a vTPM setup. After the conversion is done using MBR2GPT and changing the options to UEFI, can the secure boot checkbox be used without any issues as secure boot is going to be needed for a vTPM?
