My main OS is Windows 10 and all data I have is gathered by using bcdedit utilit. After uninstalling Linux Ubuntu and its boot menu entries I noticed that there are 2 entries called "UEFI OS", that have different ids, though are sharing one location (\EFI\BOOT\BOOTX64.EFI). Which one is safe to delete or it's better to just keep them that way?

"bcdedit /enum firmware" results:

I would like to clarify that this question is not about "EFI system partitions" - I have only one and it's on one physical disk with Windows, but about boot options, that duplicate each other (point to the same file), but have different IDs - is it safe to delete one, since they point to the one same file, or that would delete that file or there is some other critical hidden difference between them, which makes one useless and the other priceless?
