Well that error is because the drive is not formated yet.
Man, I hope you aren't really comptia certified, if so give it back.
If he gets that error it means the boot to cd ISN'T working and it's going straight to the HD or he doesn't have a good cd/reader! It doesn't matter what port his HD's are in or even have anything to do with HD's. You can even boot the windows installer off CD without a hard drive in the system.
And if he didn't have a formatted hard drive what would happen then? Ah that's right, same thing.
I honestly don't know if it matters today, but it did in the past, regarding you had your hard drive on, CS, Master, Slave... I assume that's what you're talking about when you say "ports"
