Given the problems people have been having, I have started with baby steps. I have a Dell E520, brand new with Vista preinstalled. I have also installed DDSuite Build 2610. After OSS is installed and reboots, the only OS listed in OSS is "Unknown Operating System" which I believe to be located on a small 55 MB Fat16 primary partition without a drive letter. This is Dell's Diagnostic Utility, which boots successfully! Congrats OSS! Seriously, though, running OS Detection Wizard on drive C: <OS> results in the dreaded "No new operating system found" screen. What the heck?
