Greetings all, i would like some guidance from anyone who has an idea what might be going on here: First, i have span array set-up with 2 X 160 HDD, they have 3 partitions on them, the first 2 are Win XP, the 3rd is a small partition for OSS data. (Sata II raid) Also i have Sata II 160G with vista. (just one partition) IDE 250G HDD just for storage (just one partition) IDE 120G HDD with linux on the it. (just one partition) Now what i was doing... i have had OSS working fine on the raid between the 2 XP partition and linux install. Purchased a 160G Sata, installed vista on it with all other drives disabled and not accessable. Enabled all the drives, OSS detected it automatically and gave the me the Vista logo etc etc, but when i selected it i get a blank screen with a white flashing curser in the top left. Next i scrubbed the drive and installed vista via the OSS boot system. End result was the same. If i disable all other drives Vista boots fine. What am i missing here? The Raid is onboard. Asus A8N-E MB, DD 2160 M.
