Unable to delete boot option

[zhanhao]

Hi guys,

I'm currently trying to remove my Ubuntu Grub Boot Loader from my UEFI boot option. I've tried using EasyUEFI to remove the 2 ubuntu boot options, but I only managed to remove one of it. I keep trying to delete the other ubuntu option as shown in EasyUEFI, and it allows me to delete. However, after I restart my laptop, the same ubuntu boot option still remains in my UEFI...I've tried doing this process for a few times but I still can't seem to delete it. Can someone please advise me on this?

Below are the details of my boot option:
Description:ubuntu
GPT partition GUID:{82764F10-62A6-41AC-9574-432708513E65}
Partition number:1
Partition starting sector:2048
Partition ending sector:616447
File path:EFI\Ubuntu\grubx64.efi

Thanks!
