I've been trying to install Ubuntu on an iMac that I was given. I must have spent the best part of the weekend trying to get this to work, but it was not as easy as I first thought.

I am experienced Linux tech. I am comfortable on the on the command line, and have a decent understanding of hardware.

I am unable to boot into the Ubuntu OS having installed.

iMac serial number: C02P54UWF8J4

I have a working wired internet connection that when plugged into the iMac with live USB allows me to connect to the internet, and a live USB stick which I created with Rufus

I have rEFInd installed and a copy of the binaries on USB key. I followed the steps from [this video](https://www.youtube.com/watch?v=C5G9tr1JS_Y) to create it

Mac keyboard wired and regular wired USB mouse

What I have done so far:

- I've installed the Ubuntu on the entire partition on the iMac during the install I selected the option to “install third-party software for graphics and wifi hardware” and “Download and install support for additional media formats”

- Rebooted the machine

- After that I got the ‘? Folder' and a link to support/apple.com/mac/startup

I know that the fix to this is to hold cmd + R and launch the terminal and install rEFInd to be more exact refind-bin-0.14.2

It does seem to pick the Linux partition red arrow above.

On the iMac I have the following when I look at the disks from Recovery mode and I get the following

I do a verify and I get the following.

I do a repair and get the following.

It seems that all is healthy from the perspective.

I then reboot the iMac, but I get the following screen for rEFInd.

But no option to pick the Linux OS that I have just installed.

When I select blue ‘i’ I get the following

I pop in the live USB stick. I do get the following and then I get the following options. These all seem to be only to be able to boot from the USB stick

If I boot into the first one, then I get boot into the live distro

I get the following screen for a second.

After that I get the following grub screen.

When I go to GParted I see the following.

When I select /dev/sda1 I get the following

If I try to run the installer again, I see the following when I look at the partitions.

So it does appear to be there circle 1.

Circle 2 has a dropdown which I have shown below.

Just to be sure that the OS is there I have mounted `/dev/sda2` on a directory that I created called `/temp` and when I go to `/temp` I can see the file structure of an whole OS so it does appear to be there.

It all seems to be in place, but for some reason rEFInd is not able to see the Linux OS partition (or something similar).

I tried @oldfred's suggestion and below is the output

Post the reboot only got the blue arrow as per the 5th screen grab from the top.
