Mid 2010 Mini
8gb Ram
SSD

Everything was operating fine under High Sierra and I decided to update to Mojave. All went well, computer was functioning until the reboot. Now it will only boot to the grey screen with the Apple. I did the PRAM reset, SMC reset multiple times. I booted to recovery mode and ran the disc scan, no errors reported. I performed a system recovery and it reinstalled High Sierra and everything was functional but once the Mini was powered down, the problem repeated itself. So basically I have to perform a recovery each time I need to use the computer. It will not boot into Safe mode, it will boot into single user mode but then locks up. This is what I get when booting in single user mode. No command prompt, it just locks up.

the Mid 2010 Mini doesn't support Mojave. Are you sure you have a 2010, and if so, how did you go about getting Mojave installed?
 
The SSD is formatted APFS. The SSD has been flawless for several years. It’s for sure a Mid 2010 Core 2 Duo. S/n C07dm15mdd6l

From what I recall, in the apps menu there was the icon to click & download and update to Mojave and/or I believe when I checked updates in the App Store it was an available update option.

When I perform the recovery, it installs High Sierra. I ran the disk repair utility several times on both disk menu options, forget the terminology, it came back no errors in both cases. As mentioned, it will run fine with High Sierra including Parallels & Win 10 after the recovery install but once it is shut down, using the normal shutdown procedure (not a forced shutdown with the power button) it will not reboot past the grey Apple screen.

ETA I’ve performed the recovery yet again. In Launchpad there is a dotted outline icon that is labeled OS X Yosemite, there is a blank progress bar under the Launchpad icon in the Dock.

The App Store icon in the dock indicates 1 update available, the App Store Update tab says the same but the screen is blank, no icons indicating the app that needs updating.

Using Finder, I cannot find any file related to OS X YOSEMITE, unable to drag the dotted outline icon to the trash. So it appears like maybe the update issue might be causing the hang up?

I went to the App Store and did the Check for Unfinished Downloads and completed the download for Yosemite then I was able to delete it from Launchpad. It found a security update for Safari so I’ll soon find out if the boot issue persists after it restarts. I may have been incorrect in the Mojave update, it may have been High Sierra update. I have multiple Macs and I don’t use the Mini much, the wife uses it for the most part.

I thought I had it solved with the removal of the Yosemite partial download is but that didn’t do it. Ran the drive repair on the main and mounted drive, again. PRAM reset and booted with everything disconnected including the monitor. No change.
I can Re-install the OS and everything will be as it was, all user accounts, Parallels etc. Once it’s powered down, there is no booting past the grey Apple logo screen.

Is there a way that I can backup the entire SSD including the Parallels/Windows VM, perform an erase on the SSD, install High Sierra and then restore everything namely the Windows 10 VM?
