so i have the samsung evo 860 ssd and ive succesfully managed to clone my os into it using samsung data migration and i changed the boot option on the setup screen as well(by pressing f2) and so i think it does boot up from it but my old os still shows on hard drive when i open my pc and check my drives..so how do i make the old os disappear???...do i simply format it or is there a proper procedure to remove it?
