    Re: Help to mount encrypted home with liveusb?

    I think once you run Boot-Repair you just click on advanced options after you have mounted your encrypted partition with your passphrase:
    https://sourceforge.net/p/boot-repair/home/Home/

    Is just /home the only encrypted partition. I do not think Boot-Repair needs /home mounted to update grub & kernel.
    You also show a lot of old kernels & should houseclean once system is working again.

    With encryption, you must have really good backup procedures as sometimes the encryption breaks and the only way to recover is restore from backup.

    Did you try this & some of the other links to /home issues.

    Re: Help to mount encrypted home with liveusb?

    I checked advanced options, and it offers just one option in relation to kernels under the "grub options" tab: "purge kernels then reinstall last kernel". i would prefer to install the original kernel that comes with ubuntu-studio (the distro i installed, and then changed a bit, and also the one i have in the liveusb im using).

    the kernel that is part of the ubuntu-studio version is Kernel: x86_64 Linux 4.13.0-36-lowlatency.

    the last kernel i tried to install, and didnt worked, was one of the deb files i manually downloaded (dont remember if it was a 4.16.0.041600 kernel and also a 4.15+etc), and which were the beginning of this problems, so im not sure that asking boot-repair to try to reinstall the last kernel would be the best option, or if could work rather than making the problem bigger if its missing files or something like that (since i didnt installed it properly). The 4.15.0-43 worked before i had a problem trying to upgrade the nvidia drivers, so i think i could try to use that one as first option (via chroot) before deleting the kernels.

    Do you know how it works, and should i try that option?
    if so, which other advanced options i must turn on or off in boot-repair to improve chance of success and also a new problem?

    You could just try the total reinstall of grub.
    Not sure a downloaded kernel from a .deb, would be correctly configured for Ubuntu. Best to use repository or ppa.
    And if you have nVidia drivers, that has to be incorporated into the kernel with is automatic with Ubuntu's kernel and nVidia files from Ubuntu repository.
    If you install any other way you have to manually reconfigure yourself, which is not recommended.
    For kernel not with nVidia, you would probably need nomodeset boot parameter to boot.

    Re: Help to mount encrypted home with liveusb?

    Could you guide me a bit with chroot so i can mount firefox to recover bookmarks, and maybe also cairo-dock settings, and maybe after that to also try to change the order of kernels?

    After recovering the bookmarks and make a copy of some settings, im ok with trying boot-repair as last option.

    Another thing i would like to know if possible, is if i can copy and run the partitions into a virtual machine just to check which things i can backup before resetting the system.

    As long as i can check my old files and make a list of the things i must or can reinstall, i wouldnt mind much reinstalling the system from zero.

    update.

    this tutorials explain how to use chroot to mount firefox from another os, but im not sure if i can follow the same process to recover cairo-dock settings, and also if i could change the order of kernels following that guide how could i later move the changes into the original system.

    It would be similar to this, but you have to include the ESP - efi system partition.
