I have first installed Windows 7 ultimate, then I installed Ubuntu 12.04 through WUBI. Then after few days I have upgraded it to 14.04 and the whole upgradate process finished smoothly without any error.
Then the laptop was restarted and then it can't mount the directories. It displays the message like:
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 /roo/proct failed: No such file or directory`
`Target filesystem doesn't have requested /sbin/init.
No init found. Try passing init= bootarg.
BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs)
How should I proceed?
