    Hey daniell59

    What is Emergency Mode and how do I get out of it?
    Well - emergency mode happens - when the kernel ooopps or you can not boot anything else - or that boot parameter is set.
    Where you are at now and how you got there depends on how to get out of it.
    We need the back ground details in order to advise on what to do. what specifically happens when you boot up ?

    Thanks for input.
    Yesterday for many hours my internet was down. The problem occurred when it was restored. Since I wanted to upgrade form Ubuntu 22.04 to 24.04, this is what I will do. Reluctantly I admit that I don't have the capacity to remedy the problem otherwise.

    Re: Emergency Mode

    I had some difficulty installing Ubuntu 24.04. The OS would not install on my solid state drive. I tried an old hard drive. It installed without a problem. Does this mean that the solid state drive is no longer functional?

    Maybe yes - maybe no;
    we need some diagnostic information,
    For starters does Bios see the SSD when booting up the system ?
    From the Hard drive install what shows:
    Code:
    sudo fdisk -lu
    -all we are doing is looking to know-

    Yes the BIOS did detect the SSD. There were numerous errors being generated.
    The installed drive is very old. It will serve me until my new system is up and running.

    Only seeing the one drive - does not look good for the home team.
    Anything from:
    Code:
    sudo blkid -c /dev/null -o list
    Where The switch "-c /dev/null" ensures the command is not using any cached values and polls all of your hardware directly. The "-o list" switch is an option to order the output for easier reading.

    If the kernel does not see the drive

    we got a problem

    Thanks for your informative reply.
    I had been using the SSD for several years. Then I developed a problem. Emergency mode. After that I could not reinstall the OS.

    daniell59; Ouch X10 - yukkie poo !

    As even blkid does not see the drive - it is beyond my skill set to advise on what one can do to rescue the SSD.
    Perhaps others here have some experience in such a situation.
