If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu, Fedor or whatever flavor of linux you prefer.
Here’s the quick and easy way to re-enable Grub.
1) Boot with a Linux LiveCD
2) Open a Terminal and type in the following commands, noting that the first 2 commands will acquire permission to configure grub and put you into the grub “prompt”, and the next 3 commands will be executed there. Also note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.To do this easily, go “Computer Icon” on your desktop of “fedora” for example and count drives from 0 until reach the drive where installed grub.
