Hello, I consider in buying a SSD to have my OS installed there, I've seen that it's common nowadays and I'd like to do it. I currently have my OS installed on my HDD and I'd like to know how exactly I will boot the SSD first since I have the OS already installed on the HDD. If I change the boot priority on SSD at the top it would boot how I want right ? After I have the OS installed on the SSD, can I format my partition where was my old OS on the HDD. Sorry if it's not that clear, I'm not English.
