Since I bought Windows 10 and a new SSD I would like to know how I can delete everything on my old HDD (like I bought a brand new one).I would like to install Win10 on my SSD but the problem is Win7 is on my HDD so I would like to erase everything off of my HDD so I can just install the OS on my SSD and put programs,music,pictures etc. on my HDD.Thank you for any answers!
