When I rebooted to install updates after bios screen it said boot manager is missing, press alt+ctrl+del to restart. so how can i repair/install mbr? thanx


The boot manager for Ubuntu, GRUB2, was probably broken when you were installing updates. Try using Boot Repair to fix it. First boot to the Ubuntu live CD. Open a terminal window and run the following code to install and run boot repair:

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

Then follow the instructions and options in the program to repair your boot.
