How To Repair Kali Linux Grub With Kali Linux Live Cd: Dual Boot With Windows 7

[Itachi Uchiha]

This completely works....... just remember that in UEFI you need to mount the EFI before changing to chroot directory. i.e if you get an error like "grub-install:error: cannot find EFI directory."

Add the below command before the chroot command

sudo mount /dev/sda1 /mnt/boot/efi

Provided that your EFI partition is /dev/sda1

[green gouda]

apt-get install grub
mount /dev/sda3 /mnt
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
grub-install /dev/sda
update-grub

and now reboot, that's it,
Thanks again.
