the task was too simple - I had a 256gb ssd with OSX (apfs) and Kali (osx booted with Alt pressing and Kali booting on default - I suspect GRUB was operating). I think there was a problem after upgrading to ubuntu 16 so rEFInd menu just disappeared.
I bought a new 512GB ssd and tried to clone OSX partition - it was fine but i had to tackle problem with containers, recovery hd, hidden partition and so on.
Now OSX is booting and I successfully cloned ext4 partition (Kali) with GParted and installed rEFInd via recovery hd. Now rEFInd is working but there's no option for my Kali partition.
I understand there should be a shortcut with bootloader\grub conf without Kali reinstall Kali and cloning partition once again (if ever it boots).
How do I make this ext4 partition boot (supposing cloning was successful)?
Thanks a lot!
