So i need more storage to my pc and i was wondering if i could take a 1tb hdd from my old prebuilt pc. So is it possible to use this prebuilt pc's hdd in my new pc and that hdd also has windows in it, so im afraid that if i put in to my new pc something weird might happen. Is it possible to use this hdd and will the windows in this hdd cause any problems and if it will, can i delete the windows from the hdd and if only deleting the windows is not possible, can i just delete everything from the hdd?
