What is the correct or best way to remove a Linux Distro's GRUB Menu, that is dual booting with Windows 10?
My story was that I installed Linux Mint last year, my first ever Linux Distro, but I didn't like it because it was so unstable on my laptop. So I tried removing it by following some YouTube tutorials about formatting the correct partitions and rebuilding the MBR using some applications (AOMEI Partition Assistant Standard Edition, EasyBCD, etc.) and I was able to wipe Linux Mint from my laptop, except its GRUB bootloader. I think rebuilding the MBR through those applications didn't work so I just booted into my BIOS and set Windows 10 as the first boot option and never bothered with the Linux Mint GRUB bootloader ever since.
After a while, I decided to install Deepin OS on my laptop and I have been using it for a month. Then today, I tried to remove the Linux Mint GRUB bootloader that was left untouched, because it's a nuisance to see it on the Boot Menu of my BIOS since it has no more use.
I followed this video tutorial (1:45). https://youtu.be/ZTMCKOx5Jz0
From the efi directory, I successfully deleted "ubuntu", which should be the Linux Mint GRUB bootloader. I didn't format any Deepin OS partition because I only wanted to remove the Linux Mint GRUB.
Then I tried booting into Deepin OS but it was not the Deepin OS GRUB Menu that showed up, it was the ubuntu GRUB Menu that I just deleted, that showed up and I can't boot into Deepin OS. I made sure on my BIOS Boot Menu that Deepin OS was set as the first boot option, yet the unexpected happened.
I planned on switching to Manjaro+KDE anyway, so I'll be formatting Deepin OS and its GRUB bootloader, after somebody points me on the right direction to the correct or best way to remove them. Thanks.
