Rise, make sure and pay close attention to the first post in this thread. I think the first boot is with the DVD drive on SATA20 [over by video card] and the hard drive can be plugged in anywhere else. Set your BIOS to boot from the DVD drive [it'll save time in waiting for PXE booting...] Then once the OS installs and wants to reboot, remove the power once it's in the BIOS POST portion and swap the hard drive over to SATA 20. DVD drive anywhere or disconnected. Go into the BIOS and make the hard drive your first bootable.
