Grub War – Reinstall Ubuntu/Windows Grub Boot-loader

IF your PC has dual boot Windows and Ubuntu, you may probably face this problem, GRUB war. 🙂 I also faced this problem and would like to share the solution i found by Googling . . .


Reinstall Ubuntu 10.xx GRUB after Windows 7 install ***

Boot Ubuntu 10.xx(xx- Your Ubuntu version ) from CD/USB.

Open the Terminal and run the code

You will get a list like this.

From this list find the directory you have installed your Ubuntu. In my case it’s “/dev/sda7″

Now type the following code in your terminal

Finally reinstall the GRUP

That’s all, Restart your PC. The home welcomes you.

In the Windows installation window select “Repair Your Computer”

After it identified your Windows 7 you will get a System Recovery Window.

Select Command Prompt and run the following codes one by one.

Close the windows and restart, that’s ALL.

* I faced this problem for a long time and most of the time i failed to repair the GRUP and most of the time i pushed into a situation ,reinstalling the entire OS again and that would be my hope. Reinstalling a OS is not a big task but after a fresh install talking your System into previous environment is too difficult and consumes lots of time.

** I doubted how many people gonna try this solution but i’m 100% sure there is a one person surely gonna follow this methods, THAT’S ME  . . .   😉

*** It works on my PC !  🙂
