[Bio-Linux] odd and confounding behavior with BioLinux distros 5 and 6

[John Bradsher]

Hello Tony:

Yes, the sequence and process as you see it in the last response is exactly
what I'd expect should happen. But, alas, that doesn't happen, which is the
source of my confusion. I've entered the BIOS several times and specified
the boot order, but I always get the same thing: booting only to ubuntu
10.10, even with the bio-linux 5 iso in the boot drive.
Any insights would be welcome.
Thanks,

John Bradsher
