that seems like over complicating simple stuff in my opinion.

For drives larger than 2TB, you must use GPT partitioning.
so, this basically says what kind of partitioning i should do for the windows drive?

You can see these files in /usr/sbin

And what that does is run the grub scripts to write a new grub.cfg file which is the menu you see when you reboot. It also runs the os-prober which is one of the scripts it runs and that finds other installs on you system.
so without doing the above mentioned code in Linux, the default boot-loader will only see Linux as an option to boot from and not windows?
