It does not matter if I filmed this on virtual box or not. You need to follow the exact same steps, if you want to dual boot on an SSD or a harddisk.

If you want to install linux to your SSD or harddisk then you need these things

  • an working usb stick 3.0 or 3.1 these days of 3GB+
  • an application to write the iso to usb like mintstick or etcher (more info)
  • figure out how to boot from usb on your hardware (more info)

We use grub-customizer to tell him which partition or which desktop it should boot up with by default.

We also change the /etc/lightdm/lightdm.conf so that we can boot up without typing a password. That is the autologin option. Suited for desktops, less so for laptops that leave the privacy of your home.
