I wanted to install Aeon. In a youtube video, the dev said it’s increadibly easy. It even asks if you want to backup existing users and it leaves their home folder as is. This info was backed up by the docs.

Once I clicked on “install now” it reminded me that there is no back once it starts installing the system. I clicked on OK because usually the installation process starts at the end of the configuration phase.

It then loaded and I fearing that it really erases everything. I stopped the process by shutting down the computer.

The computer does not detect any filesystem. It should be ext4 if I remember correctly. fsck yields no result. It suggests using two different blocks but with no success. I can’t mount anything. Hence I also can’t fix grub.

Did I just erase my disk within one second? If so, I can just continue. If not, I’d like to backup some stuff. (Most is backed up, but not the most recent stuff)

    Fsck is not a tool to find lost partitions or partition tables. Start from a Live USB stick (or one of the data rescue linux systems) and see what your harddisk/ssd looks like. Maybe the data is still there. If it’s gone, try if a tool like testdisk finds your old partitions / old data.

    There are some recovery tools available: https://wiki.archlinux.org/title/File_recovery

    From the docs of this OS I have never heard of before

    Backup Existing Users

    Optional This question will only be asked if the following conditions are met:

    The selected disk has a compatible Linux installation containing user data stored in a Btrfs /home subvolume.

    The installer USB is larger than all the data in the /home subvolume on the existing installation.

    If you were prompted to backup users it definitely wasn’t ext4 lol you probably corrupted your btrfs filesystem

      Thanks!

      Good to know that I just deleted the last months because I missed reading the fineprint.

      Edit: it is 100% my fault. I don’t blame someone else for my data loss.

      This just shows that there is still room for improvement in the installation process.
