I am trying to reset Windows 10 without saving any files.
On my first attempt it hung at 87%.
Second attempt it hung at 1%.
The PC still boots Windows and prompts for one of the logins.
I have downloaded Windows 10 x64 (November 2019 edition) to a USB memory stick, thinking I would do a clean install.
But I am stymied trying to get to the BIOS or the Boot Menu - I have been trying pressing ESC many times to no avail.
