"because kernel does not have driver included" Is this in fact the case? I have two machines less than three year old which DO NOT boot off the usb drive for some odd reason. Like yourself I have gone over to usb flash drive for installing new linux releases. The solution I have found is to install PLoP which can be put on a CD or 3.5 floppy. I am just in the process having had two CD/DVD 'die' recently to putting my last DVD drive in a remote drive case and putting 3.5 floppy drives (off which I've got four) in each machine for booting purposes. james
