Hi@essexrest,
Welcome to the HP Support Community! I'd like to help!
I see you are experiencing boot issues with the HP All in one PC.
I have a few recommendations
- Update your computer to the latest BIOS from HP.COM.
- Make sure the Windows and HP support assistant updates are up to date.
- Go to System and Security and then click on Power Options. In the left pane, click on Choose what the power buttons do. Next, click the Change settings that are currently unavailable link. Under the Shutdown settings section, uncheck the Turn on fast startup (recommended) option to turn on the feature.
- Try doing Reset PC Keep my files from windows and check if it works fine.
Hope this helps! Keep me posted.
