Hi All: While freeing my System from Windows (parallel installation) the Win. - HardDisk-Managagement tool informed me that something has been "corrected" on a disk partition. (My Linux LVM - device!) /dev/hda5 contains one Volume Group "vg00" and the Logical Volumes "lvol01", "lvol02" and "lvol03" It seems to be a Windows boot sector or something like this, because of "55aa" ??
