Though Ubuntu 12.04 comes with a stable GNU of Linux it has been reported of a number of issues on of the most frequent of which is being Ubuntu failing to restart by normal restart procedure. How can we solve this issue?
This is generally caused by BIOS issue or hardware setup problem. GRUB is what loads Ubuntu so updating the GRUB solves this issue in most cases in older versions of Ubuntu. This can be done as follows:
a) From terminal we have to navigate to location of grub as follows: Sudo gedit/etc/default/grub
b) Find GRUB_CMDLINE_LINUX=””, using text editor change it to GRUB_CMDLINE_LINUX=”reboot=efi”
c) Save the file and run it with command sudo update-grub. Try rebooting now and Ubuntu should reboot normally.
