As zab noted, I too am unclear about your intent.
Regardless, this may help when you’re ready: Partitioning during installation
Linux can read Windows partitions but not vice versa. So, when you boot in Windows you’ll only see your Windows partition files (and any storage partitions that are not ext4 format partitioned). But yes, your files will all be there, they won’t be gone. It doesn’t matter whether SSD or HDD.
