Have the UEFI Option in the boot menu of the ASUS K42F notebook. Regrettably, boot to USB is not an apparent option. Have emailed Asus support and the reply demonstrated no knowledge of the feature. There is an option that allows the entry of "command line" entries. The setup utiliities are from American Megatrends (AMI). Hoping to connect with a forum member that has experience wth this interface. Some images are uploaded to a microsoft online folder: Not sure that ths is the appropriate place to post but guidance sought.
