I wish i could leave windows behind me.
Why do you need windows?
Linux and windows Partitions in the same HD will cause problems "eventually".
Dual boot is possible and should not cause problems unless a virus destroys all partitions. For that you make backups.
i confirm : you can use windows & linux on the same computer in dual boot : no problem;
however, if you use windows , its better to run your linux os in a virtual machine.

if the host is infected your screwed, and you're not safe with dual boot, either there are some exploit to spread the infection to another partition that is using another so
the only possible way is to have two ssd, and one only active at any time, so you must un-plug the power from the other, so it's not recognized
