ReactOS is all-original, written from the ground up as a clone of the
Windows design
[2] Can you dual boot with ReactOS and a Linux
operating system like
Debian? If you can, is there a place where I can find instructions on
how to do so?
yes, see

have to be
ported before it can be run on ReactOS?
No
