I thought I would post this out there incase anyone runs into the same issue I did. I tried installing Home Server on Dell Precision 390s (two of them) and both blue screened after the second setup part (the one that asks for SCSI drivers). After spending a couple hours switching between machines and neither one working, I discovered that I needed to go into the BIOS and change the SATA options. The default was RAID autodetect/SATA and I had to change it to SATA/PATA. It wasn't configured for RAID but that setting was blocking the install.
Anyway, thought I would post that so that I could potentially save someone a headache!
