Okay possibly you tried to install Linux after Macos + Clover Bootloader. In normal conditions you should have installed Macos and Clover latest and they check entries Windows and Linux when you input required selections in config.plist. To make it worked and controlled by Linux Grub Loader (In your condition you are possibly on it and it corrupted your Clover Bootloader) Then you should configure Grub Loader. Here I found a reference link and try the instructions carefully please; 3 hours ago, luky35 said: I'd like to have Bootloader starting from which I can select to run macOS or Linux.

luky35 Posted March 13, 2020 Author Share Posted March 13, 2020 @uisik34 I don't have Windows installed, only macOS Catalina. I did a partition on the disk and installed Ubuntu there. Now I only need Ubuntu because the bootloader does not start where I can choose which OS I want to run. The problem is how to fix it.

I understood your point and i replied above please follow the link up. If you only want to keep linux on system and remove hackos from your system you need to repair grub loader instead then you can remove macos installed partition from gparted. I hope the explanation is clear. Link to comment https://www.insanelymac.com/forum/topic/342954-dualboot-catalinaubuntu/#findComment-2712238 Share on other sites More sharing options...

I have two OSes, macOS Catalina and Ubuntu, I just can't set the bootloader to show me both systems in the start menu and then choose which one I want to use.

duffs Posted March 13, 2020 Share Posted March 13, 2020 one way would be using EFISTUB. Skip installing grub, move kernel files to EFI partition then add custom boot entries to clover. good luck Link to comment https://www.insanelymac.com/forum/topic/342954-dualboot-catalinaubuntu/#findComment-2712322 Share on other sites More sharing options...

Yes I clearly understood your conditions dude. You have two operating systembs ubuntu + hackos and which your latest installation ubuntu corrupted your clover bootloader. In this scenario you are unable to see any bootloader to select Ubuntu or Macos Link to comment https://www.insanelymac.com/forum/topic/342954-dualboot-catalinaubuntu/#findComment-2712327 Share on other sites More sharing options...
