Ubuntu – Ubuntu 13.10 – Target filesystem doesn’t have /sbin/init

bootgrub2

After installing an update I restarted my computer. Ubuntu failed to boot, so I used boot-repair to try to fix it. After running boot-repair grub2 was removed and the Ubuntu os was no longer detected by the live cd. I reinstalled grub2 which worked, but I got the error:

mount: mounting on /dev on root/dev failed: No such file or directory
mount: mounting on /sys on root/sys failed: No such file or directory
mount: mounting on /proc on root/proc failed: No such file or directory
Target filesystem doesn't have requested /sbin/init.
No init found. Try passing init= bootarg

After this, it brings me to busy box. I found solutions for the error. fsck and e2fsck don't work.

Boot summary here: http://pastebin.com/5CeCMQjx ubuntu is installed in sda1.

any help?

I was really concerned about this error behavior as well. I was without Internet and Ubuntu Live CD so I had to try the following procedure which successfully solved the current error.

This procedure is applied on the following failure characteristic as well: Serious errors were found while checking the disk for /. So I used following procedure as proposed in Solve serious error /:

  1. During booting up on Ubuntu hold the Shift key down so you will enter into the "Advanced Boot Options" for Ubuntu.

  2. Press e to edit GRUB2 boot entry.

  3. You need to change the GRUB2 boot entry from "ro" to "rw"

=> Instead of mounting as read-only, mount for read-write

  1. Press F10 to boot

  2. After booting change the crub.cfg file in terminal

    gksudo gedit /boot/grub/grub.cfg

so the changes you made in the boot options will be saved permanently.

Find the lines: 

linux    /boot/vmlinuz-3.13.0-24-generic root=UUID=[bunch-of-numbers] loop=/ubuntu/disks/root.disk ro rootflags=sync  quiet splash
  1. As you did in the grub menu change "ro" to "rw", => Instead of mounting as read-only, mount for read-write

It worked in my case, for Ubuntu 14.04 LTS as well. I hope it does for your case as well.
