I pasted something incorrect (from a tutorial) into my /etc/fstab file. As a result, the root file system will not mount when the machine boots up. I know what needs to be fixed in /etc/fstab, but I cannot save the file (or any file) because only file system the system boots as read only. As root, I tried: mount -o remount,rw / to no avail. The error message cited the section of bad options that I pasted into /etc/fstab. I read some stuff about booting into single user mode by adding 'single' to the end of the kernel parameter. I can't seem to find the kernel parameter. On the grub menu, I highlight Ubuntu and press 'e' which brings up a file with some sort of configuration, but there is no 'kernel' parameter to be found. I'm relatively new to linux. Can anyone help me figure out a way to fix my /etc/fstab file so that Ubuntu will boot normally? ubuntu fstab share|improve this question asked Feb 15 '15 at 22:06 Daveh0 2613 Can you make a live USB and boot to it?

What are the exact error messages? –Gilles Feb 15 '15 at 22:38 @Gilles - it worked after I boo
