UEFI Windows 10 installation?

Question

Windows

I have an Acer Extensa 2511G laptop, I want to switch to UEFI (currently Legacy is in the BIOS)
How can I do this? Do you need to format the disk?
SOLVED:

1. Opening PowerShell as Administrator
   
2. Enter :
   mbr2gpt.exe /disk:0 /validate /allowFullOS
   -
   mbr2gpt.exe /convert /disk:0 /allowFullOS
   
3. Reboot along the way changing Legacy to UEFI
   

End
