After updating bios
It seems that the failed flashing procedure affects the hard disk in some manner, and that, consequently, forces you to start from a scratch.
And, on the ”Bad scale”, that’s only ”Moderately Bad” if we take into consideration the possibility that you might need a motherboard replacement.
You should either contact the official support or try explaining your problem to knowledgeable folks or PC enthusiasts.
That’s your safest bet to tweak BIOS settings and retrieve full functionality. It seems ludicrous to do it again, but that might just resolve your problems.
Namely, you probably installed the wrong version or interrupted flashing and bricked your motherboard.
Nonetheless, for a novice user, it can lead to a prolonged hardship.
Sadly, it’s not easy to access Safe Mode like before.
