Can't boot Wubi after upgrading to 14.04 from 12.04: "Target filesystem doesn't have requested /sbin/init"

  • 772

So I decided to upgrade to 14.04 from 12.04 on my Wubi installation, using update-manager -d, but I can no longer boot into Ubuntu. When I try to, I see the message mount:mounting..."etc, then "Target filesystem doesn't have requested /sbin/init". Does anyone know how to solve this?

mount: mounting /dev/loop0 on /root failed: Invalid argument
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /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.
12.04

    Steven, I've found a solution that works, that is, if you haven't tried to reinstall yet:

    If you can find your boot commands, find the line that says:

    linux /boot/vmlinuz-3.13.0-24-generic root=UUID=D014E45... etc...

    Change "ro rootflags= sync" to "rw rootflags=sync"

    That's it. Just that one character. Nothing else. Worked for me, hopefully it does the same for you. Here's hoping.

    and

    Daniel - thanks for posting that solution, my dad's laptop was suffering from this, and I managed to get a remote session on it and repair it for him thanks to your post. He's very pleased :)

    For what it's worth, I also updated the grub regeneration files in /etc/grub.d/10_linux to ensure that it remains set to "rw" after a kernel update. Just replace this line:

        linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro ${args}

    with

        linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} rw ${args}

    In summary, to recover, I did (from memory):

    • boot from xubuntu cd (Try ubuntu without installing)

    • open terminal, locate root volume on the windows drive, mount it with:

    sudo -i

mkdir /mnt/recovery

mount -o loop /media/xubuntu/Data/ubuntu/disks/root.disk /mnt/recovery

apt-get install vim

vim /mnt/recovery/boot/grub/grub.cfg  # set "ro" flags to "rw" as per Daniel's comment (#8 above)

vim /mnt/recovery/etc/grub.d/10_linux  # change "ro" to "rw" as above

reboot

  2. During Grub, press "e", that will bring up the editor, locate to where it says ro and change it to rw.

    You have to do this everytime you boot.

    To make the change permanent, run gksu gedit /etc/grub.d/10_lupin after booting (replace gedit with your favourite editor, use sudo nano /etc/grub.d/10_lupin if you are in the tty), locate the line which says

    linux   ${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} loop=${loop_file_relative} ro ${args}

    and change the ro to rw, like this:

    linux   ${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} loop=${loop_file_relative} rw ${args}

    Save the file, and run sudo update-grub.
