    You can use the Report Post button to request staff to edit the title. Give it a day, though, to see what other information shows up. You can also search here (and elsewhere) to see what that "Authentication token manipulation error" message or what "cannot remount block device" means.

    If it is refusing to remount the root partition with write permissions, that may be because it has detected filesystem damage - if there's an option to run a filesystem check from the recovery menu (instead of dropping to the root shell) you could try that, if it completes successfully it should leave the filesystem mounted rw anyway and you can then drop back to the root shell and try the password reset again

    However based on your earlier post mentioning 'loop0' and '/host' I'm guessing this is a wubi install? in which case I'm really not the right person to advise since I've never used wubi

    Re: really, really locked out, can't change password

    I believe youre getting that error because its only mounting the filesystem in read only. After dropping into the root shell from the boot loader, you can force it to mount it in rw with

    mount -rw -o remount /

    then continue and change the password

    This indeed looks like a wubi install. Maybe you have to remount /host as rw first. I'm not a wubi specialist, but it might help.

    Ubuntu 10.something has reached end of live. This means that if you want to resume using Ubuntu you can best upgrade to a later version. You can create a live disk, boot from that and try to mount your partition from there. First mount the ntfs partition where it is installed, then mount ubuntu/disks/root.disk, which contains your file system, and rescue any files you like to keep. Then reinstall. I don't think fixing this complicated stuff on an end-of-live version is really worth the effort.

    I hope you didn't encrypt your home directory. If that's the case recovery will be nearly impossible.
