Up to plan B : boot while pressing F11 to get boot menu : 2 options : CD/DVD or HD (acceptable, but invertion of BIOS order)
Selecting CD/DVD (without a CD in the drive) : get message "reboot or select proper boot device"
When I press ENTER, he boots from my HD !
What can I change to make him start from HD, instead of the procedure above ?
