    +1 on jamesisin suggestion

    Bootinfo report should show fstab. It should see the file in line 52 with the boot files, and then output the fstab further down, but I do not see it. Did it get renamed to .backup or something and not get restored or restored to correct location.

    Why?

    Perhaps I missed something, but I did copy/paste the blkid from the boot-info output and matched it with the fstab he posted. Seemed correct to me.

    Can someone else review it please, since I could have missed something.

    At the bottom of the boot-info, there was a comment about what a repair would do.

    Boot-Repair does not create a missing fstab. It may add an efi entry to an existing fstab if converting from grub-pc to grub-efi. Actually I do not think Boot-Repair even does that, but it is the grub2 install of grub-efi.

    The fstab entries shown in post #1 look ok, but no fstab is shown in the correct /etc/fstab location for bootinfoscript to list it.

    Run these command like I did.

    fred@fred-Precise:~$ cd /etc
    fred@fred-Precise:/etc$ ls fst* -l
    -rw-r--r-- 1 root root 1164 Jul 19 11:00 fstab

    I don't see how the list command will solve the problem.

    He's not solving the matter. He's demonstrating whether the fstab file exists.

    Alternatively you could do this:

    Code:
    ls -al /etc | grep fstab
    "We're all in this together, kid." --H. Tuttle (a.k.a. H. Buttle)
    "Maybe it's a layer 8 problem." --thatguruguy

    Okay then. It exists.

    And does it have correct permissions? That was part of original question.

    Then post this, as it should be the same as your original list in post #1. And if all is correct as you say then it must work.

    cat /etc/fstab

    cat /etc/fstab
    Yes, I have all the proper permissions. I really don't see how concatenation would help me here but I did it. It didn't fix anything.

    It is not that you running it solves anything, but often having many eyes reviewing it sees something that is otherwise missed. I have looked at issues for hours and then see the problem later. Often quicker when many can review it.
    If everything is then correct we move onto what else may be the issue.
    But please post both commands outputs.

    Oldfred was not asking you to concatenate anything. The command cat /etc/fstab simply puts out the contents of the fstab file which needs to be seen to compare with what you posted in post #1.
