Today, I decided to check how vulnerable my computer was. I wanted to test the physical security of it. I use Linux (doesn't matter what Linux I use) and there are methods if you were to forget your password, to reset it. Below are some steps how you can do so.

How to secure your system to avoid this from happening?

You can either 1) Encrypt the entire system with veracrypt (if it allows you because I couldn't do it) or 2) configure GRUB password authentication. I will be showing you how to configure GRUB password.

Thanks for the guide.
Will this also work on an already installed distro?
When i installed my linux i couldn't encrypt my drive even though i chose to encrypt it.

Yes, that I know it only works if the distro is installed.

Isn't useful. The Linux root partition should be encrypted. The data partitions should be encrypted separately. Secure boot should be on and set-up to protect the kernel.
