The High Sierra install attempt messed you up. I fought with this for 3 weeks, replaced several drives before I figured it out. It has installed APFS formatting. I even called Apple on my 2012 13” MacBook Pro. I could only go to Mavericks, anything above gave me kernel panics. Of course they didn’t tell me. This caused me days of work, about $600 in new drives and a lot of unhappy customers. It does this on SSD and SSHD drives.
This goes along with other things Apple is doing to put third party upgrade and repairmen out of business.
So:
A: format it it APFS and stay with High Sierra or
B. Reformat it GUID and stay with Sierra or earlier.
I tried Mohave, but I did try the Beta and then it would not even see my external GUID USB formatted disk that I had just done the install from.

I have not tried Mohave yet, but I did try the Beta and then it would not even see my external GUID USB formatted disk that I had just done the install from.
