I recently made changes to my fstab file and, upon reboot, noticed I had an error in it. I get the typical mount error on boot. I went to try and modify it by entering the read-only mode but then, since it's read only, I can't access it. Is there a way around this or some way to delete the file so I can use the backup (which I'm pretty sure works)?

Remount the filesystem read/write, either using the option on the menu, or by running mount -o remount,rw /

option in which menu? the booting menu? –  ZekeDroid Jan 21 '14 at 3:36
@ZekeDroid, the recovery menu. The one that lets you choose to fsck, remount rw, drop to a root shell, or boot normally. –  psusi Jan 21 '14 at 14:20
