Hey guys,
today I decided to upgrade my parents pc with an SSD and do a clean windows install on it. Everything went fine, I installed their office 365 etc, until I removed the HDD. When i tried starting the pc it gave me an error telling me to 'reboot and select proper boot device.' but in the bios it doesn't detect the SSD as a boot device. In the 'miscellaneous' options it did show up. I restarted the pc multiple times when the other HDD was still connected, but when I removed it it stopped working.
I hope anyone can help,
