Yes, that is what I am thinking. I have often accesed (viewed) Windows
files from linux but not the other way around. I trust 10 times more on
Linux security than in Windows, thus having dual-boot in my mind,
diminishes my security ten-fold. Is there any safeguard in Windows (or
in Linux) to avoid this access to a different partition?

How does the boot partition play a role here? Is the software planted in
Windows (or Linux) and then executed at boot?

thanks very much.
