When trying to go into safe mode,it sends me back to the blue screen after being at a black screen. Now a 4th choice is added: “use a device”.
That's bad.
(1) It is possible to rescue files at a Command Prompt (if you can get one). I found that
Notepad worked very well at a Command Prompt of the Recovery Environment...
(a) Plug in a USB drive on which to copy your files.
(b) Get to the Recovery Environment, & at the "Choose an Option" screen,
click "Troubleshoot > Advanced Options > Command Prompt".
(c) Enter Notepad at the Command Prompt.
(d) In Notepad's File menu, select Open.
(e) Set Notepad to display all file types with its requestor at bottom...

The files you want are likely in the folders at "C:\Users<your user name>". Remember to Refresh the screen after a paste. Additional notes...
o Notepad's left pane has only "Quick Access", "Libraries", & "This PC".
o Click This PC to switch from C: to the USB drive & back again.
o Double-click a drive or folder in the right pane to open it.
o Right-click a file or folder, & select Copy. That seemed instantaneous.
o Go to the USB drive, right-click in Notepad's right pane, & select Paste.
I had an hourglass for just about a minute - or was it two - for 1.3 GB.
o When the normal pointer reappears, right-click in the right pane,
& select Refresh - or I think you never will see it.
(2) Do you have a restore point at...?...
"Troubleshoot > Advanced Options > System Restore"
Choose one from before the latest updates, & it should undo them all.
(3) For an external Recovery Environment, make Win 10 Installation media here...
https://www.microsoft.com/en-us/software-download/windows10
Download Windows 10 - This is always the latest finalized Windows version, currently 1909.
Download MediaCreationTool1909.exe & run it to make a Windows 10 Installation USB drive or burn an .iso to DVD. Follow the instructions under "Using the tool to create installation media". As it says, match it to the Language, & Architecture (x64/64-bit or x86/32-bit) of the computer on which it will be used. The Windows
Edition to take is "Windows 10", which includes both Home & Pro.
(4) Then, to boot it...
(a) Insert the DVD or plug in the USB Installation media.
(b) Boot or reboot the computer.
(c) On your HP, the ESC key gets to a Startup Menu, as in...

HP Consumer Desktop PCs - Updating the BIOS (Basic Input Output System)
It says, "Turn on the original computer with the issue, and then immediately press the
Esc key repeatedly until the Startup Menu opens." Here is the menu...

(d) Then press F9 to see whether the Installation USB drive will show up.
If two show up, choose the one that is UEFI.
(e) If it were a DVD inserted, you get a message to "Press any key" to boot it.
If not pressed in time, the DVD will be bypassed & Windows will try to boot.
(f) When the Installation media boots, select "Repair your computer" instead of to install.
The computer will reboot to the Recovery Environment at the "Choose an Option" screen.
See whether that recovery environment will work better than the one you've been using. But it's tougher to get to Safe Mode from it...
(a) "Troubleshoot > Advanced Options > Command Prompt".
(b) See Option 3 here...
