As a sort of follow up to the post I made on my alt account, would I need to do to anything to Grub to continue using Linux Mint after removing Windows or would I still be able to boot into Linux Mint without having to do anything? As stated in the previous post, Windows is installed onto an SSD and I want run games from that SSD but I’d need to reformat the SSD in order to use it.
Edit: I don’t need help with this anymore but because it seems like there is some confusion, I’m including the fact that I have Linux installed onto an external hard drive and Windows was installed onto the SSD which is in the laptop. I’ve already remove Windows from the SSD and reformatted it to ext4 so I can run games from it.
Fair note: A lot of these comments are under the assumption you are using the os_prober feature in grub to detect the windows install. While this is usually the case, if you have ever supplied a manual entry for windows in /etc/grub.d to specify where your windows install is (I was forced to do this because os_prober refused to see my windows system after recreating my EFI partition), you will need to delete that entry again in order for the windows option to disappear on grub.
It would still boot your Linux mint, but you would have a windows entry in the boot menu that didn’t go anywhere.
That’s not a problem for me. I’ve never had to manually add an OS to Grub before.
