I installed dual boot ubuntu/macos mojave using refind. However I used a different drive for each system (120GB SSD for each). My problem is making refind understand that. Here is the list of problems:
Ubuntu got the preference and would load without giving me a chance to choose.
When I manage to access rEFInd boot menu, I couldnt boot macos. Looks like the the startup system is not found.
I found a way to load one or another but takes time and I have to start the system 3 times.
This situation is quite annoying. Does anyone knows how could I fix this issue either from macos or linux os?
I think the problem is that os are installed in different drives, but how can I make rEFInd find both os?
Thanks,
Ramon
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
When you say "Ubuntu got the preference," I interpret that to mean that when you turn on the computer, it boots to Ubuntu without showing the rEFInd menu. If that's correct, then you've essentially described a boot coup, and you should be able to correct it with one of the methods described on the page I've just referenced.
When you get rEFInd to appear, are you saying that it's not showing any macOS option? If so, then it sounds like Apple may have changed the location of its boot loader again, although if so, this is the first I've heard of it. There's a small chance that the macOS option is not showing up because of use of APFS in conjunction with a failure by a macOS update to also update the firmware. In that case, installing Apple's APFS driver in rEFInd might fix the problem. See the "Apple's APFS" bullet point on the rEFInd drivers documentation page for information on this.

Oh, the problem is most likely unrelated to your use of multiple physical disks. If it is, though, hitting the Esc key in rEFInd should show the macOS entries. If that helps, then setting the scandelay option in refind.conf should work around the problem.

If rEFInd shows a macOS option, then either rEFInd has found a boot loader or you've created a manual boot stanza. I'm afraid your screen shot isn't showing me anything helpful. Please describe with more detail and precision what's happening. A screen shot of the rEFInd screen, including quotes of the descriptions rEFInd shows for the non-functional macOS boot options, might be helpful. Even more helpful would be a description (or a video) of what happens when you select an option that doesn't work. That is, does the system hang? Does rEFInd display an error message and then return to its main screen? (If so, what does the error message read?) Does it look like the OS is starting to load but then it hangs?

Actually it appears the mac option on rEFInd but it does not find the os to
boot. I will send you some images to clarify.
I will follow your instructions and get back to you with what happen.
Cheers,
