Here we see that the grub has been "stored" in our system.
The script is by @ghulselmans and we find it
How to find where Grub is installed
We open the link
It is advisable to create a folder eg grub location and extract the contents of the file there
We read the README file instructions and see that
Run the script as sudoer:
sudo ./bootinfoscript <outputfile>
or if your operating system does not use sudo:
su - ./bootinfoscript <outputfile>
We control the rights of bootinfoscript if it is controlled and executable and if not we do
`Run 'as an administrator will create a result fileRESULTS.txt RESULTS1.txt ...
and find out where grub saved and if you have more than one!
