Windows 10: Windows 10 stuck at "Diagnosing your PC" and will not boot

Hello. I have an Acer Nitro 5 AN515-54 51M5 gaming laptop. Yesterday, I noticed that the Wi-Fi connection randomly dropped twice so I decided to do a Network Reset. Then, the Wi-Fi disappeared and there was no Wi-Fi options, and nothing fixed it. I updated my Wi-Fi drivers and it did not fix. Eventually, I have fixed it by doing a System Restore that was automatically created earlier that day after I reinstalled Python. Everything went well and I shut down my PC.

Stuck in Windows 10 Upgrade

My computer seems to be stuck in a Windows 10 failed upgrade loop. I was running fine on a beta version of Windows 10, and then I came downstairs one morning to see it repeatedly booting, attempting to repair, then rebooting. The steps I've taken to diagnose are:

• Attempting to boot off a USB drive (with all drives disabled in BIOS) - this fails at the point of the blue windows screen
  
• Attempting to boot the machine itself and getting into "repair/safe mode" using F7
  
• Looking at the BIOS for obvious failures (e.g. RAM that should be there is missing) - nothing obvious is wrong.
  

I am fairly certain the build version was 9926. For many months, the system would attempt to upgrade, and then say "it failed" for some reason and roll back.

Suggestions for next steps?

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
