Hi Guys
today i have an easy way to Repair Grub or Restore Windows MBR

Step 1 : get a live version of linux
You need a live version of linux (distro doesnt matter) to install the application
you can burn linux on cd or usb and start live

Step 2 : install Boot-Repair in live linux
open a new Terminal (Ctrl+Alt+T), then type/copy/paste :

Code:: sudo add-apt-repository ppa:yannubuntu/boot-repair

Code:: sudo apt-get update

Code:: sudo apt-get install -y boot-repair

Step 3 : Using Boot-Repair

1. launch OS-Uninstaller (System->Administration->Boot-Repair)
2. you got two choice Recommend Repair & Advance Repair

Recommended repair

launch Boot-Repair from System->Administration->Boot-Repair

or by typing 'boot-repair' in a terminal

Then click the "Recommended repair" button. When repair is finished, then reboot and check if you recovered access to your OSs.

Advanced options

Warning: the default settings are the ones used by the "Recommended Repair". Changing them may worsen your problem.
Don't modify them if you dont know what you do ! .

thats all

i tested the application by myself but not the installation method cu it was already installed on another distro

also i founded ubuntu secure disk which integrate by default os-uninstaller & boot-repair you can found it here :

hope u like it

Hi,
Just want to say that I am new to Linux but love it. I learnt the hard way that grub remains and can get messy. I had to reinstall windows a couple of times before I came across this post. Brilliant & Perfect solution for me. I now have confidence to try different distro's.
THANKS

I repair Grub like this:

1. Boot your computer from the Zorin DVD or from a Live USB with Zorin on it. Select "Try Zorin".
Note: only use the DVD of the Zorin version that you wish to repair. So for 14.04, use the DVD of 14.04.

2. Now you need to find out what's the name and the partition number of the root partition
(the partition on which your Zorin has been installed). In case you have a multiple boot system.

3. Start Gparted Partition Editor to see your partitions.
Tip: the root partition of your Ubuntu will usually be formatted in EXT4. The EFI partition
will probably be formatted in FAT32, and it'll have the boot flag.

4. On my computer, the Zorin root partition is called sda3. For the sake of clarity I'll use
that situation in the rest of the how-to.

5. Open a terminal window:

a.

Code:: sudo mount /dev/sda3 /mnt

b. press Enter

c.

Code:: sudo grub-install /dev/sda --root-directory=/mnt

d. press Enter

e.

Code:: sudo reboot

f. press Enter

6. Reboot the computer normally, so don't forget to take out the DVD first.

7. Start Zorin normally

8. Open a terminal window:

a.

Code:: sudo update-grub

b. press Enter

9. Reboot your computer.

10. Celebrate!
