Just providing an update that I was able to upgrade to 10 without issue and to shed some light just in case someone else is in my same position later . Some specs first
C:/ 1 TB ssd
F:/ 500gb SSD
E:/ 1TB HDD
I disconnected F & E drives from my mobo and proceeded with the update using the windows media creation tool and chose to keep all my data. After update I powered off and reconnected drives but these drives didnt show, not even in disk management after a restart. I came across a youtube vid that said to try Windows memory diagnostic tool. After running, both my drives appeared and mapped correctly. Also to note my windows 10 is activated already. I know there is some grey area on if the free update was still available. I can confirm as of today it still is.
