I tried the first option. And got into the setup utility page.
But I don't see any "auto repair" option. Nor any "troubleshoot".
Tried the other tabs like advanced, boot, ... but no repair or troubleshooting
Under boot tab, I got
Fast boot. (Disabled)
Secure boot. (Enabled)
And under boot option priorities,
"Boot option #1. (Windows boot manager)
Any of these useful to try?
However at the bottom I found f9: load defaults
I guess this resets the tablet to factory settings. Right? Let's keep this as my last option.
