Hey, i used to dual boot like 3 years ago and i would like to know everything about it, do i need another hdd? how can i make 2 systems or 3 systems work well together?
Process varies on the boot loader of the operating systems in question.
i dont understand? my main system is windows 10.
All operating systems use a boot loader to load an operating system.
There are no industry set requirement for boot loaders of an operating system.
Refer to technical manuals, websites or other resources to identify the actual boot loader in use by the operating system that you are referring to and level of support/compatibility with other OS that you are considering.
