Still it works well, I have omited the root= line on my USB drive and it 
works like a champ,  always boots.

The problem with the root line on a USB boot drive and using a root= 
line is you have to adjust it depending on how many drives the computer 
has, ie my desktop has four drives and my laptop 1.  Removing the root=/ 
line makes it work on both machines without farting around without 
adjusting the root line at boot for each.
