I'ts been at least a decade since I did this, but I recall aomething 
called rEFInd I had to install to help the process.

There is also a boot option to hold another key to specify which 
alternate storeage device you wanted to boot. c was CD -  the only 
device I used. Maybe u will get you to your USB.


My other suggestion: is there a boot flag on the USB somewhere, perhaps 
the efi partition?
