Hi. I see you have a USB flash drive connected.
Depending on the Boot Order set in the BIOS and which devices are enabled to boot from - this can cause issues.
You have gone to great detail in concentrating on the Device Manager,
But the obvious place to start is in the Disk Management which will show drives which were detected at boot time.. This does not mean that it will find all that are attached.
Right click on the Start Button and select Disk Management.
Then click on 'Action' in the menu and select 'Rescan'. Do this more than once until ALL drives are detected.
If it finds your missing item - it may not have drive letters allocated. It needs a letter for each partition which you want to see in File Manager etc.
Right click on the partitions you want the system facilities to see - and allocate a letter. The default is good enough but you can choose another letter if you wish.
I have a rack for my hard drives that lets me plug in a drive to boot from. Occasionally I get the prompt to say 'No boot device found'. On the second attempt it may find the boot device - otherwise I open the BIOS and make sure that the boot device is at
the top of the order. Then it always boots up.
If you installed the preview and it has a storage drive - always make sure that the same storage drive is attached when you boot the preview. Otherwise it will complain about the drive being missing or needing repair.
BTW: I never dual boot OS's because when testing previews - you may get the boot manager confused by drives being disconnected or changed to boot a hard drive for a different system.
