Ok so i currently have a lenovo prebuilt pc that i got last Christmas. I recently decided that i was going to build a new pc, building it as in buying all new parts except for my ssd and hdd, i am trying to use them in my new build. When i got my pc it already had the os downloaded onto my ssd. I am trying to use the ssd in my new build for the Operating system, but currently i have all of the 250gb used up. I just dont know what to do. How do i completely clear the ssd, including the drivers that were preinstalled before i bought the pc and the operating system. Is it possible? I generally dont know what to do. Do i just clear everything except the Operating System and the drivers, and will i be able to use it in my new build? If anyone can help me and explain how i can use my current SSD with my Operating system and things on it for my new computer, I would truly appreciate it...
