Dear Ubuntu Community,
I always find interesting questions and relevant answers in your forums, and this is the first time I really need to ask for more specific help.
I used for many years xubuntu 12.04 and I tried to install ubuntu 16.04 alongside in another partition: I did not want to touch 12.04, until I was sure my hardware was working in 16.04, and the installation instructions let me think that I would preserve my data/pictures/etc, and I would be able to select the previous system.
Hence I have started my 64-bit pc from a USB stick. To do this I had to explicitly go in the BIOS and select the UEFI boot for this device (other options were failing to boot).
When asked, I let the system unmount existing partitions. Updates were not downloaded during installation.
At the end, I encountered a problem similar to this: https://ubuntuforums.org/showthread.php?t=2331567
Anyway I was able to still restart the system with 12.04 without any data losses.
I did another attempt, wired connected to internet, I have enabled the download of the updates, including third parties software, and I turned off secure boot inserting a password.
Since there were already the partitions from the previous trial, I used the advanced tool to format those ones. I was carefully selecting only new ones, leaving untouched those existing from 12.04.
When asked, I assigned to one partition the mount point "/" and to the other "/home".
Before proceeding I was warned at a certain point that I might encounter difficulties in booting other installed linux versions. I did not see this message before, and I thought that this would affect only the most recent 16.04 installation, and I decided to proceed (the alternative was ending the installation).
Now I am in big troubles: I cannot start 12.04, since it seems it cannot load /home.
And I still cannot boot 16.04. Further attempts created only more partitions, but I hope to delete them once I have a working system.
I have created a Boot-Info report: https://paste.ubuntu.com/26491528/
My first most important question is: can I still recover the data in my past 12.04 /home ?
Next question would be how to get out from this mess, and have a working 16.04 installation that can boot, but first I want to backup all data, if this is still possible.
Any help will be appreciated,
kind regards,
