I cannot answer the following my thread with this error message "Body is 9 characters too short"
Hopefully Jack E find this message. Thank you!
Thank you so much for your suggestion.
suggestion (BIO Security) started the resetting process, but I went to
bed when it was 65%. This morning when I booted it, it took a long time
(spinning with Acer logo), but went to "Your PC ran into a problem..."
blue screen and shut it off by itself.
Now because I followed
your first suggestion, F12 works (I can select W10 USB thumb drive), but
it doesn't boot from it, and goes to the same blue screen and shut off.
Thank you again and any more suggestions?
