I can't for the life of me figure out how to boot to USB.

I can enter the BIOS and turn off secure boot and set my USB flash drive as the first bootable device but I can't get it to boot.  The boot menu shows my flash drive as UEFI (flash drive name).  I think that may be the problem because I cannot find any option to enable legacy boot.

Is there a way to disable UEFI boot and is there a way to boot any bootable flash drives that work in other systems?

If this is limited to UEFI boot and does not support 64bit, how on earth do you make a PE4.0 32bit support UEFI boot?

Thanks for any help you can give me,

Dave
