Windows 10: Is it possible to delete the EFI Partition after converting MBR to GPT

Hello everyone,I am attempting to convert windows 10 installation from MBR to GPT using the MBR2GPT.EXE tool. https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gptThe documentation states:MBR2GPT.EXE converts a disk from the Master Boot Record MBR to the GUID Partition Table GPT partition style without modifying or deleting data on the disk. Does this mean that if windows is unable to boot, the EFI partition can be deleted? In other words, is it possible to revert GPT back to MBR if something fails in the process of converting MBR to GPT?

Convert only one partition on the disk from MBR to GPT

I need after a crash ,to reinstall Windows 10 using Micosofts "installation media" but get the following response:

“Windows can not be installed on this drive. The selected disk has an MBR partition table.

On EFI systems, windows can only be installed on GPT disks”.

Does anyone know how and whether it is possible to convert only one partition (of 4) on the disk from MBR to GPT

Kind regards Alex
