I recently built a new pc and set the computer to download the OS into the ssd. the problem is that most programs download into the C drive (the ssd) and boot from there. My hdd which is 2 tb is where i would like them to boot from but for some programs i can't so i want to change my hdd drive to my ssd drive (change the letters from E: to C: ). The HDD would be the c drive and the ssd would be the E drive. this way things could work better for me. The only reason why i want this is because my ssd is only 120 gb which i bought mainly for the os. I don't mind deleting things from the HDD cuz it's mostly just games but i don't really want to reinstall the os again. Please help.
