Greetings from Berlin

[Fridulix]

Hello Linux Community and guten Tag!

I live in Berlin, Germany. Within limits I am quite an experienced user. A few days ago I installed upon a friends recommendation Linux Mint 18 as the second partition on my iMac. Liked it pretty much from the first moment ! Aesthetically, functionally, the terminal - great system, just good vibes.

Only trouble is that - in spite of updating, reinstalling Grub, installing rEFInd, using boot-repair and following a couple more recommendations from help page and a Linux book - there was so far no chance to ever get started again from my Mac OS X 10.8.5 partition. Mint shows me the other partitions at starting and later on the desk, but never not allow me to choose the partition. If you have a quick idea ....?

Best ahead,
Freudolix

Hi, and welcome!

Hi and thanks for the welcome everybody.

I am pretty busy at the moment, so things will take a while. One problem I could solve meanwhile seems to have been a very small one. I did not have a wired keyboard, not even thought about that first. But there seems to be a moment, when you switch the partition that Bluetooth is not available and you need the return key. With a USB keyboard and rEFInd I could meanwhile return to the OS X part, as well as to a live USB stick. Just rebooting to the installed Cinnamon is not possible. I may have damaged something, when I shut down the computer without keyboard.
But now I got the Iannubuntu Boot Repair from the Sourceforge net and will try it. Just, if I am doing something very wrong with using Boot Repair, or you know that re-installation of Cinnamon is unavoidable at this point, I'd be glad about a hint.
To Pierre: The question about which terminal commands I (wrongly?)used I will answer later, when I find time to sort it out and understand it all a bit better.

Cheers!

Hello world of Linux, here I am again!

I reported already that I had troubles to switch back to macOS as the original partition on my iMac13.1. Cinnamon worked great in the start. Just the way back was blocked. I did all installation with a Bluetooth keyboard that was accepted from Cinnamon as well as my wireless mouse. Perhaps the crucial point was the demanded exit via return key that was not working. I switched off and restarted several times via the main On/Off. Switching meanwhile is solved via rEFInd and a wired keyboard. (If of interest: rEFInd displays even a former Windows emulated installation that was erased years ago, but perhaps formatting is still present. The macOS service tool does not see that.)

First I tried the info of hagensieker's post (Sat Oct 17, 2015 10:42 pm) and followed his solution:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair.

Was no effect.

Actually with a live stick I can start Cinnamon. I prepared then a stick with downloaded Iannubuntu boot repair iso, that works obviously as a kind of start up system but ends after a while with grub troubles, declaring I am in a "Legacy Modus" , restarting in an EFI seating should activate the missed function - once started - with the live stick, the installed version does not open and the system does not boot repair stick.
I got the following info several times:

Unable to mount Linux Mint 18.1 Cinnamon 64.bit

Error mounting /dev/sdb1 at media/mint/Liux Mint 18.1 Cinnamon 64-bit: Command-line
`mount-t "iso9660"-o
"uhelper=udisks2, nodev,nosuid,uid=999, iocharset=utf8,mode=0400,dmode=0500"
"dev/sdb1" "media/mint/Linux Mint 18.1. Cinnamon 64-bit"' exited with non-zero exit status 32: mount:dev/sdb1 is already mounted or /media/mint/Linux Mint 18.1 Cinnamon 64bit busy.

That's what I have. And here I am kindly asking for advice if there is one who understands these troubles. Is there a chance to solve that story with one of the miracoulous terminal commands or is it now time to better reinstall from the live stick?

Thanks in advance and best,
Fridulix
