Thanks. I'm not expert enough to tell if you are right. The symptoms I described already and here they are again: With USB Debian installation pendrive plugged in, pressing power button together with volume up takes me into the front page of the PC settings: there is: ->Boot Manager ->Device Manager ->Boot From File ->Administer Secure Boot ->Setup Utility I enter `Boot Manager', and there are two possible options: Windows Boot Manager EFI USB Device (General UDisk) I choose the second and here I am in Debian installation menu. There is: Install 64 bit install Graphical install 64 bit graphical install Advanced options ... Install with speech synnthesis 64 bit speech install I tried with both Install and `64 bit install', and also, now, with `64 bit graphical install'; and, in all those cases, what happens is that the image becomes confused and the keyboard sticks and no command is more possible. > If it happens in GRUB, then Knoppix 8 would be a highly interesting > alternative.

So, as far as I understand, Debian live isos will also probably fail and all I can do is waiting for Knoppix 8 iso image to be downloadable... Rodolfo
