By secondary windows drive : I mean in windows 10 I have a C drive the main drive. and I have a D drive (the secondary drive for extra storage). I’m curious if I put data onto it or copied data from it would windows 10 have any sort of issues with that data or even the entire drive?
Like everyone said, it’s fine. They both know how to use the same filesystems, mostly. The only exception is that your Linux install might happily let you mess with or delete essential Windows system files in a way that breaks your install, which Windows would probably try to protect you from. So just, y’know, stay out of system directories
