Hi @enderpirate98, welcome to the forum!
In my opinion, it is never a good idea to dual boot Linux and windoze, on any computer. If you absolutely must use windoze (you don’t, btw, but you may think you do), the only safe way to do it is in a VM.
I explain in quite some detail why dual booting is stupid, in my big post here:
There is no way to guarantee that. The only way to keep your data safe is to have multiple, external backups of it. This is especially true when you’re doing delicate operations that are likely to cause data loss, like repartitioning your drives. However, it is also true with general, every day computer usage – hardware failure happens all the time, HDDs and SSDs malfunction, often with total, unrecoverable data loss. That’s usually not a big deal when it happens if you have your data backed up, but can be a total disaster if you don’t. Storage is fairly cheap, but data can be priceless.
