A few months ago I dual booted Windows and installed Remix OS a form of android for pc that runs on the Linux kernel. I got rid of that about a week later and grub was still there so I think I got a windows startup disk and finally got rid of that grub and booted straight to windows. Anyway I decided to dual boot Linux a few days ago set it up perfectly no problems but now after a few runs I’m getting the old remix os launcher and no Ubuntu launcher. It can’t find remix os so boots straight to windows. No Ubuntu option however if you go to grub command line and type exit it takes you to the Ubuntu boot loader. I want to get rid of the remix os grub boot loader but not the Ubuntu one.
