On another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB - its just a boot drive
Do you know how to start PC from USB?
what I am going to do is show how to set PC up so you can get to safe mode from start up, its normally off
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose command prompt
Enter these
BOLD commands and press ENTER after each.
(Note the colon after C with no space; then the spaces which are important - one after T before / & T before { & } before B & Y before L)
C:
BCDEDIT /SET {DEFAULT} BOOTMENUPOLICY LEGACY
EXIT
You are back to the boot screen -> Shutdown the computer.
Boot back up and "immediately" start tapping F8 (That means power button - then F8).
Hopefully that should get you into Safe Mode.
--------------------------------------------------------------------------------------
To reverse that you can use the same steps and type these (again note spaces)
C:
BCDEDIT /SET {DEFAULT} BOOTMENUPOLICY STANDARD
Restart but F8 will not work now.
now see if you get same behaviour in safe mode
then see if any of this helps -
