Disclaimer:  I probably don't know what I am talking about and am not  
familiar with the various modes of the Dell RAID controller etc.

Why would you expect it to affect booting?  I suspect that the  
machines BIOS makes the RAID available no matter what the mode and  
that the boot happens on the "bios" disk (through a "bios" interface).

Again, this is not my area of knowledge but that is what I am guessing.
