Pretty much, yeah.
I’d recommend using two physical drives (SSD/HDD) instead of two partitions if you can, because windows update sometimes messes with the bootloader. But most laptops only have one drive so that’s not always possible.
Do keep in mind that formatting a drive (e.g. to split it in partitions) will erase all the data, so make sure you have backups!
I heard that somewhere in the US there were parts of a nuclear power plant being delivered by steam train. So that’s basically one steam engine supplying another! (^^,)
I can’t seem to find an article about it anywhere, so it might be an urban legend :(
