Hi Cybrarian!

Today I’m gonna share with you 3 ways to restore GRUB boot-loader after losing it when you decided to dual boot windows with Linux.
The reason for this problem is that windows doesn’t recognize neighboring systems, and it’s a common problem.

Now I will show you  how to restore this by using 3 methods:

1- live CD or live USB
2- by EasyBCD
3- by boot-repair

First (1st) method: by using live CD or live USB –

1- Burn the distribution on CD or Flash storage (USB).

2- Boot it in test (try without install).

3- Open terminal and write or copy this command to show your Disk:

sudo fdisk -l

4- Find the installed Linux partitions, often you’ll find next to it “EXT” 

5- Copy this command and replace sda3 with what commensurate with your condition:

sudo mount /dev/sda3 /mnt


6- Then copy this command to do mount:

sudo mount --bind /dev /mnt/dev


7- Next:

sudo chroot /mnt


8- Copy this command to install GRUB:

grub-install /dev/sda


9- Finally copy this command to update GRUB:

sudo update-grub


10- Finished.

Second (2nd) method: by Using EasyBCD on Windows –

1- Download it from this link

2- Run the program then go for this steps:

– Add new entry

– Linux/BSD

– From Type choose: Linux(GRUB) or you can choose (GRUB 2)

– From name choose the name you want for the system.

– From drive choose the partition where you installed Linux

– Finally  click “Add Entry”.

And this program has many features like using METRO screen and choose the time for booting.. etc…..

Third (3rd) Method: by using Boot-Repair –

This is the easiest way to repair your boot screen.

– For windows all you have to do is download the program and run it.

– For linux open terminal and type or copy:

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

And to run:



Finally form the screen choose “recommended repair”

I hope this was helpful to you. I’ll be happy to hear form you, feel free!

  1. I had windows 7 on C drive and Linux on E drive. After I formated C and installed windows 10 I cannot use Linux on E drive. I guess is that GRUB loader is deleted. Will this tutorial be helpful in my case and help me access Linux also beside my windows 10? Any help appreciated
