Fix GRUB loader in Ubuntu 18.04 || Install/Re-install Grub || 100% working 🔥🔥

Hello Friends,
In this video I'm going to tell how you can fix the GRUB loader in Ubuntu 18.04 i.e., how you can re-install grub bootloader after you have installed windows or deleted any operating systems partition.
Hope you will like the trick.
But do it at your own risk. I will not be responsible for any sort of problems or damage...

Commands for fixing Grub:
1. sudo fdisk -l
2. sudo blkid
3. sudo mount /dev/sdaX /mnt
4. sudo grub-install --boot-directory=/mnt/boot /dev/sda
