I changed my Mobo, CPU, Ram, Processor, Psu. I plugged my SSD into my MSI MAG Z490 Tomahawk motherboard and it won't show the drive in boot priority list. But if I check the Board Explorer, it shows that Samsung 850 EVO is plugged in. I MSI guy on the phone was extremely rude and suggested I needed to buy a new copy of windows. Any help? Is there a setting I missed to help it discover the drive?
