Ubuntu 14.04 not booting after error message. /tmp could not be mounted

If you installed Ubuntu 14.04 using WUBI and after installation when it booted it showed an error:
Serious errors were found while checking the disk drive for /. 
There were three options:
press [I] to ignore, press [S] to skip mounting and press [M] to mount manually. 
After pressed I, it showed /tmp could not be mounted and my Ubuntu isn't booting.

Lot of people will get or  got this kind of error after installing Ubuntu 14.04.I also got same error but after some modification i fixed it.
Please Follow This Step 

  1. In Windows Boot Manager, select Ubuntu.
  2. Press any key and enter GNU Grub2 menu.
  3. You can press "e" to edit GRUB2 boot entry.
You need to change the GRUB2 boot entry from "ro" to "rw",
linux   /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk ro   quiet splash $vt_handoff
linux   /boot/vmlinuz-3.13.0-24-generic root=UUID=AAC884AC1F144321 loop=/ubuntu/disks/root.disk rw   quiet splash $vt_handoff
Press F10, you can boot in Ubuntu 14.04.
and you can fix GRUB2 boot entry:
sudo vi /etc/grub.d/10_lupin
Change the line:
linux   ${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} loop=${loop_file_relative} ro ${args}
linux   ${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} loop=${loop_file_relative} rw ${args}
Regenerate GRUB2 boot entry:(type in terminal)
sudo update-grub

After this all step surely you can use your new ubuntu 
So enjoy!!!!!!!!!!!!!!!!!!!!!!
