After OSS is installed and reboots, the only OS listed in OSS is "Unknown File System" which I believe to be located on two partitions NTFS, 1.) windows VISTA, in HD SATA primary partition with a drive letter C: and 2.) windows XP, in other HD SATA primary partition with a drive letter D: Seriously, though, running OS Detection Wizard on drive C: <OSS> results in the message "Unknown File System" in the icone. Somebody know to explain this is? Simply OSS wizard not recognize File Type System NTFS in SATA HD.
