I was using MountManager in Ubuntu 12.04 to set user permissions in mounting hard drives. I set each partititon to be mountable by everyone instead of admin only. Then I clicked Apply in the file menu and it gave me the message successfully updated.
Upon restarting Ubuntu, just hangs on the splash screen and does not boot any further. Windows still boots fine.
How can I fix these? please help
thanks
From LiveUSB:
my fstab looks like:
overlayfs / overlayfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda5 swap swap defaults 0 0
/dev/sda7 swap swap defaults 0 0
Is this corrupted?
