I upgraded from 13.10 to 14.04, and when I restarted the computer and selected Ubuntu, the black screen said:
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. BusyBox v.1.21.1 (Ubuntu1:1.21.0-1ubuntu1)built-in shell(ash) Enter 'help' for a list of built-in commands. (initramfs)_
Can anyone help me fix this?
