I am going to sell my pc, but before I do, I would like to replace the current storage with a new SSD, as to avoid the new owner having any way of accessing my files. But I know that when I replace the storage the PC will be without an OS, and I would like to sell it with windows pre-installed as to not confuse the potential buyer. Not sure what to do regarding this, should I just remove the old storage and put the new ssd in, or should I install and initialise the new SSD first, and then remove the current drives? Thanks!
