If you still need both, it’s an okay option, though it can be a little challenging to set up and maintain if you’re not as tech savvy. But in that case, to address the original question: learning how to restore your bootloader would be helpful.
But if running Windows in a VM works for what you need, that’s an option too (that’s what I do).
Or if you want to play around with Linux before committing, running it from a USB drive is also fine.
Bootloader stuff is less important if you’re not dual booting. Windows has a tendency to attempt to rewrite the bootloader when it updates.
But if you’re interested, it never hurts to learn about your BL!
