Ubuntu – Reboot command is not working as expected in Ubuntu 14.04.3


I have a fully working EFI dual-boot of Windows 7 and Ubuntu 14.04.3 in that I can select either Ubuntu or Windows from my grub menu and that OS boots correctly.

However, on my Ubuntu install when I use sudo reboot or otherwise issue a restart command it does not return to the UEFI BIOS or GRUB menus. Instead it always returns immediately to the Ubuntu OS and does not give me any option to switch OS to Windows.

This is a major issue for me as I wish to use grub-reboot to boot into my Windows 7 OS remotely. Currently I can only achieve this by using grub-reboot then powering off and physically pressing the on switch on my PC.

Am I missing some option for the reboot command that allows me to "fully" restart back to the GRUB menu or UEFI BIOS?

sudo reboot and shutdown -r now from the terminal should work properly. May be something wrong with your grub2 setup. Try grub customizer

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

to fix your default O/S and other options.

If something wrong with your boot may be you need to try boot-repair from a Live USB/CD

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
