Is it possible to tell the Ubuntu installer to NOT look for Windows/ignore it (but leave it intact), so that it doesn't attempt to use GRUB.

  • Thank you mook765, I would want to agree and can you elaborate on the basis for your comment, please? For example, please share reading materials that form that opinion that could me, or your own practical experience. Thank you! – therobyouknow Aug 27 '19 at 08:10

    I didn't read carefully, my mistake. What is described in the link provided is a problem specific to Apple, I think your question is placed well there on AskDifferent. Cross-posting is not very appreciated on StackExchange. – mook765 Aug 27 '19 at 08:48
  • +1 upvote from me for your honesty mook765. There are 2 parts to this problem, mook765, one is with Ubuntu and how it installs on a mac (hence posting here) and also the Apple startup manager itself and how it 'finds' and 'connects to' the OS partitions, hence my posting there. I've also been upfront and honest about the 2 posts. – therobyouknow Aug 27 '19 at 09:36

  • "Possible duplicate of https://askubuntu.com/questions/62440/is-it-possible-to-boot-ubuntu-using-the-windows-bootloader" - no, not really. That question is to restore Windows bootloader after installing Ubuntu. My question is about stopping Ubuntu installer from using GRUB in the first place. But +1 upvote from me to you on your comment, karel, for your good effort - no harm in knowing related but not exactly similar problems to encourage lateral thinking! – therobyouknow Aug 27 '19 at 11:05
  • To install Ubuntu in EFI-mode without the boot-loader you have to run a live session ( Try Ubuntu without installing) and in the session, run sudo ubiquity -b. But how are you going to boot Ubuntu without Grub? – mook765 Aug 27 '19 at 12:12
  • What do you think about living with Grub. Grub can be configured to boot to Windows by default and the timeout can be reduced. As far as I understand, all three OS are able to boot and configuring Grub might be an acceptable solution. – mook765 Aug 27 '19 at 13:01
  • Thank you but no, mook765. I'm happy to have GRUB just for Ubuntu. But I don't want it interfering with anything else on my system. It shouldn't have to. My question was about that. – therobyouknow Aug 27 '19 at 13:37
