GRUB Boot Loader Not installing on Hard Drive

[jalil md desa]

Dear Team,

I have problem to create GRUB boot loader. I have followed instruction and guidance given in forum by _defalt on 26/7/2017. I still have error as below:

Need your help
Thanks in advance.

Your efivars kernel module is not loaded.

Run this command to test it:
#efivar-tester

UEFI variables are not supported on this machine.

#modprobe efivars

Test again:
#efivar-tester

This will no longer report an error, and now you can install grub the same way you were doing before.

Dear Team,

I believe efivars not install in my system. The errors are as below:

root@kali:/# efivar-tester
root@kali:/# apt-get install efivars-tester
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package efivars-tester

Can you help me to get efivars package, I saw in github but anyway to get easy from this forum.

Regards

I can't see any error when you enter efivar-tester. It means it is installed. If you are unsure about it enter:
dpkg -l | grep efivar

If it's not installed enter:
apt update
apt-cache search efivar
This will give you the full name of the module

apt install efivar-full name
