Unable to access BIOS or boot menu

[Davidghdez]

Hello, I'm unable to boot my Prodesk 600 G5 with a USB drive to load Ubuntu.

Reading the information from many support threads I tried the following.

Using common keys F1, F3, F9, F10, F12, ESC, DEL. - No success.

Bought a display port to HDMI adapter, using all the common keys - No success.

Connect the PC directly to the wall outlet - No success.

Updating BIOS - No success.

I get the HP Sure Start screen every time and then Windows loads. 

Can someone reply with any ideas or a solution on how to boot with a USB drive?

Thank you in advance.

Nex thing I tried:
Testing all USB ports for my keyboard - No success

Using a different keyboard (USB wireless keyboard) - IT WORKED.

Conclusion, in my case the keyboard is not being recognized by the BIOS, I'm assuming it's a cheap keyboard.

It's so weird because in my +20 years experience this never happened.

I leave this in case you face the same problem.
