User Case

“I bought an SSD, installed windows 10 on it, and then plugged in the HDD that I used before as it has 2TB and the SSD only 250GB. I want to use the SSD for Windows and a few games and apps, and then the HDD for other storage.

Whenever I turn my computer on it starts up with the HDD instead of the SSD even though the SSD has priority in the BIOS. When I manually force the computer to boot with the SSD, everything works fine. But it won't do it by itself. How to fix the problem? Any help would be appreciated!”
