Hi Celso ,
Do as follows : Secure Boot disabled
Load Legacy Option ROM enabled
Boot List Option Legacy
I had the same problen and after setting the values in the BIOS as above
everything works fine.
OK it's bad advice. If it works for you, fine, but I think it's bad
advice to suggest three things that are inappropriate for essentially
all use cases: secure boot does protect against known boot kit
malware; legacy option ROM has numerous known malware exploits; and
the legacy boot option is incompatible with booting Windows. So the
advice breaks Windows boot, which cannot boot in legacy mode because
it wasn't installed in legacy mode, and it makes everything less
secure without improving usability.
