Windows 10: Second hard drive not showing up in windows 10

I have an asus gl752V it comes with a 1T HDD and 128gb SSD. I got the laptop last week and it comes without windows, only MSDOS installed on the SSD. So I have installed windows 10 on the SSD. Everything was perfect until I found out that the HDD isn't recognized. So I went to disk management and made "new simple volume" then format and then added a letter to the hard drive. Then it had shown up in "This PC". I wanted to change storage directory under System, but unfortunately the HDD doesn't appear in that screen. So I restarted the laptop thinking that changes apply after reboot, but then the HDD disappeared again from "This PC" and to make it show up again I had to do the above once again, but after I reboot it disapears again. Any idea what the problem might be?

Second Hard Drive Not Showing Up after Win 10 Update, the 2nd HDD says "unknown device". The drive does not have a letter and is not initialized

I had the exact same issue. Extra internal drive a no show in device manager. It was in the BIOS. I fixed it by changing the SATA controller. When I reinstalled mobo it was not set to IDE.
