Just wanted to come back and add a few things
It is completely safe to remove a hard drive in case it's in the way, I personally didn't remove it, just disconnected the 2 (sometimes there could be 3) cables from the hard drive.
Another thing is I didn't manually uninstall any old dvd drives in device manager before installing the new one, It all happened once I booted to windows
remember to ask any questions you may have before doing anything! Thank you.
