Question:

The windows7 OS successfully removed, but can't boot in Ubuntu, said the bootmgr is missing. Also the hdd password is frozen.


Solution:1

Try Boot-Repair.

Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can't boot Ubuntu after installing Windows or another Linux distribution, or when you can't boot Windows after installing Ubuntu, or when GRUB is not displayed anymore, some upgrade breaks GRUB, etc.

You can either install Boot-Repair, or download it, and boot from the CD.

To install it, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

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

Source:Boot-Repair


Solution:2

The boot manager for Ubuntu, GRUB2, was probably broken when you removed windows. 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.
