[Recover grub back again after if it is lost of these reasons-- windows 7/xp/vista/8 installation, uninstalled package grub from Linux system.]
So you were enjoying life using Ubuntu and then one day you had to install Windows for that one application your boss makes you use and now no more Ubuntu. When we need a dual boot system it’s always best to install Windows first then Ubuntu due to Windows stripping out the boot loader but what if you have no choice? or a crash that corrupted the boot loader. Boot-repair to the rescue.
- run Ubuntu media in live mode.
- connect Ubuntu to Internet source
- open up a terminal and type the following:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
- click “Recommended repair” and apply. make sure you leave the “Reinstall GRUB” check-box ticked. Now reboot your system. now you can see GRUB back.
