I'm trying to install Leo4All2 in a Medion PC (I'll post the specs later) and by far I'm stuck at the very beginning because the USB keyboard gets stuck (can't even toggle caps lock and num lock) so obviously the install won't start.

Anybody else had troubles getting the USB keyboard working during pre-install and knows what to do in this case?
I tried three different keyboards and it's the same, I can use them to enter the BIOS setup normally and yes, USB Keyboard and Mouse is enabled in the settings.

What am I missing?

Hi,

You can post detailed PC configuration?

Maybe good, you can try boot in "verbose mode" (-v) and post picture of error.

Cheers,
