Windows 10: Computer apparently gone

If there is a specific thread for this problem please make the move

My PC seems to have died. I found it shutdown this morning and it would not boot into windows stopping at the BIOS screen. I plugged in the flash drive full copy of Windows 10 and it would upon reboot it would not start into it's install. Now everything stops at the Megatrend page the F1 command does not start setup. The PC is current on my account page. I disconnect all of the drives except the boot drive still no joy getting it to start a fresh install. The system is 5 years old so if there is no suggested solution to my problem I will just upgrade to a Ryzen based system.

I forgot to mention both the keyboard and mouse are directly plugged into the PC.

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

How do I reformat entire computer?

Update:

• I probably should have taken better notes on what I've already tried
• I created the USB flash drive as directed in #26. That did indeed install W10
• I now am at the same point that I described in my post #6, with my drives still being dynamic rather than basic and the following exceptions from my post #6 (not sure)

- Now all of my data is on the C:\ drive rather than the various folders like "My Documents
- I apparently need to reinstall my display driver. The display is wonkey (circles are ovals) and I can’t seem to adjust using the settings menu.
- Other partitions that came installed with my HP notebook like System, Tools, and Recovery now have different drive settings

So I’ve come almost full circle except with a few steps backwards. I’ll try more carefully to follow Post #2 and #7 as suggested. Possibly I missed as step with those earlier. I’ll also check with my other software to see if there is a simpler way to revert my computer back to the way it was out of the box.
