Hello, a fresh Windows 10 installation would likely erase the second partition if it's not the primary drive. The second disk, being a dynamic partition, would lose its data unless you back it up first. Your two 2TB HDDs should be safe to keep their data intact after the clean install.
It's probably not the final attempt I made, though it could have been partly my mistake. When uncertain, go with no.
