I currently have 3 hard drives in my system, two SSDs and a HDD. I installed the second SSD about 3 weeks ago and my computer has been working fine since. However, I turn it on today and get taken straight into BIOS, and I see that my first SSD, which contains Windows 10, is not being detected, while my other drives are. I tried using different SATA connectors and power connectors to the SSD, as well as plugging the SATA cables into different ports on my motherboard, but still no success. Do I have hard drive failure? I bought this PC pre-built almost 2 years ago and have replaced everything within it except for the drives. I want to know if there's anything else I can do before I have to boot from a USB and reinstall windows on another drive.
