I have the problem I explain in another question, Dual boot isn't working; cannot come back to Windows 10 which was closed bc is off-topic, but fortunately I received some useful advice.
Considering that the black screen and the PC booting Ubuntu automatically starts happening when I change BIOS configuration, disabling Fast Boot and CSM Support, and since that moment I haven't seen the manufacturer logo and neither reaching the BIOS again, I wanna ask if, considering this, the solution cannot be restarting the BIOS.
At this point, I don't know even if it's possible reaching BIOS at booting bc any button works to me (or i'm not doing it well)
I read that I could physically reset BIOS by removing CMOS battery and a seconds later putting it again. If I do it, wouldn't I reset the initial configuration that always gave me access to Windows? Or the only way is the process of deleting and renstalling an Ubuntu Supported version?
I know that maybe the question is not accurate at all, and could be closed, but would be good to receive some answer before bc I don't know a lot and I'm really stuck with this. Thanks.
