It seems like grub is screwed up.  My boot order was CD then internal 
windows disk.  I even changed it so that the internal windows disk is 
first in boot order, same error 17.  I don't think it would reconfigure 
the numbering of sdx drives.  Even if it did, it should  still look at 
the bios and use the internal windows disk?  The usb external doesn't 
show up in bios, even if it is on.  Maybe it is just this stupid Dell 
XPS 410, I have never had so much trouble with other systems.
