Dual booting is an option, but without two separate drives (or sometimes even with windows on a separate disk), windows update will just nuke your EFI partition and do its own thing.
It’s possible, but I probably wouldn’t recommend to a beginner, as bootloader issues are usually not fun to fix (had to do it a lot when I was dual-booting back in the day)
So I don’t really have an unused side/old computer that is operational. I’m an engineer, but not the computer kind.
