So if there is any way, like hardware, to get to the data on the disk I would appreciate a lot your help. I actually need only to take some important data from the disk, moving it for example to an external drive, after that I can also restore the Mac Book. Use efibootmgr - You can type sudo efibootmgr -v to see all your boot options and the current boot order (the BootOrder. The most direct way is to download it from rEFInds Sourceforge repository. What could I do to load macOS again, or get in a macOS shell from where I could probably remove the rEFInd solving the problem and being able to boot to macOS? If you installed rEFInd in OS X, it wont be in the path from Ubuntu, so youd need to find it on your OS X partition or obtain a version in Ubuntu. I'm also unable to boot into safe mode at start, I assume because it loads rEFInd before macOS operating system is loaded. Selecting that one, it loads into the Minimal Grub Bash, from which I don't know how to proceed.

Yesterday I accidentally reinitialized the disk on which Linux was installed, and when I restarted the Mac, in the rEFInd boot menu there was no more the icon to load macOS, but only the one for Linux. I have a MacBook Pro 15" late 2015, on whom I created two partitions on the main SSD, on one there is the macOS, and on the other I installed Linux Mint.
