    Hello Jim.
    I hate to dump this on you as a first reply but I’m stuck.
    32bit system
    Ubuntu 14.04
    I was deleting old kernels and deleted a newer one 3.13.0-37-generic.
    my screen is stuck on GNU GRUB version 2.02 beta2-9ubuntu1
    I have two options both are memory tests 86+
    What are my options for reinstalling my needed kernel or Is there a back door to my terminal from here?
    I run my business on this and I really need to access it.
    Please be descriptive. …I’m on the verge of being old.

    Can the Cd be an older version of ubuntu or will it force me to install that older version?

    My current kernel was 3.13.0-37-generic #64
    There was another labeled 3.13.0-37-generic #57
    And the one I deleted was a lower sequence and it was labeled
    3.13.0-37-generic #46
    Was it wrong of me to remove #46?
