    When i did this in the repair menu before it said

    Total identified Windows installation: 0
    The operation completed successfully.

    and then i did

    I would get your files off the HDD while you still can.

    Using RE you are booted into memory X:
    If your windows directory is now assigned E:
    then the command would now be E:

    Total identified Windows installation: 1
    [1] E:\windows
    add installanation to boot list? Yes(Y)/No(N)/All (A)
    so the answer would be yes

    also do the checkdisk as posted above

    Josh, You are not in a windows environment, do not expect what you are working with is the same as windows.. You are in a recovery GUI..
