Laptop not detecting hard drive, does detect SSD

Hello. I am using a Dell Inspiron 7577 laptop running Windows 10 that has an SSD that stores the OS and then a large HDD that stores pretty much everything else. Earlier, while editing in Premiere Pro, my laptop bluescreened. When it booted again, I got to my desktop with no issue. When I tried to return to Premiere Pro, I found that the program had failed to locate the majority of my files. I searched around and discovered that I am no longer able to access my HDD in any capacity and that it is not listed as a drive in my File Explorer and I could not locate it in the BIOS. I called Dell tech support and I was told that I should pay to have diagnostics run on my laptop which I am not inclined to do. Any help here would be much appreciated.
