After my upgrade to 12.04, whenever Ubuntu tried to boot up it prompted an error indicating that it can't mount (NTFS) drives and I had to press S twice, once for each drive, to get to the login screen.
Now that I have disabled the auto mounting of drives, I guess I've made a mistake and Ubuntu no longer starts. I tried recovery modes (although I don't exactly know how to handle them), and then I see only a line which says mounting failed and permission was denied. It doesn't move past this.
How can I get Ubuntu to boot again?
/etc/fstab? If so, you'll need to boot from the Live CD/USB, and add that file's content to the question. – mikewhatever Aug 27 '12 at 0:23
