If any problem you can reply me

just do the all steps

then tell me what happens

I've found a few that will ask for a password XXX as it turns out there is none. You just hit enter with it blank.

to reset it is to clear it with the CLR_CMOS jumper/pins on the motherboard.

Another way would be to reflash the bios
