    Hi,
    I have a Lion dmg file.
    When I tried to intall the file, the installation program notifies me that no GUID-partition-table is found on the disk.
    I have a boot camp with windows xp installed.
    Can anyone here share some experience on how to upgrade the OS?
    :confused:
    Thanks in advance.
