Hi. I just built my first PC. Initially installed OS (Win10) onto a Samsung evo 250gb SSD from a disk in connected optical drive. Had plans to add a new 1TB seagate internal HDD. I didn't connect the HDD initially until everything was installed and working. With the HDD connected now though the computer gets stuck at the startup screen. I'm using the same SATA cable initially connected to the optical drive (only had two cables to begin with). Reconnecting to optical drive makes it work fine. I've checked the BIOS menu. SSD is picked to boot from. Another issue is if I connect an older external drive internally, it will start up fine but see the drive as unformatted. Putting the external drive back in its enclosure and connecting via usb shows all data still there. Any idea what the problem is in either or both cases? Thanks!
