Hello! I built my current pc about a year and a half ago but am now looking to wipe my computer. I have one 500GB SSD and a 1TB HDD and have Windows 10 installed but I upgraded to it from Windows 8.1 so I do not have a windows 10 disk, just a windows 8.1 disk. Would it be possible to reset my pc through Settings > Update & security > Recovery or would I need a Windows 10 disk? Thanks!
