    Hi,

    I am trying to install Leopard on my iMac G5 (1.6 GHz, 1 GB, 160 GB)
    which is currently running Tiger.

    Neither the installer nor the disk utility or Leopard's startup disk
    tool can see the current Mac OS X partition (which is the only partition
    on the drive). The installer list of partitions and disks is just empty
    and disk utility shows the hard disk but not the partition.

    After booting the Leopard installer twice I removed the DVD with the
    next reboot and got a questioning Mac symbol on the screen. After a
    while I reached the bootmenu screen and my OS X partition appeared and I
    could boot back into Tiger.

    The OS X parttion is the factory-installed Tiger installation on a
    normal Apple Partition Map hard disk as from the Apple factory.

    Did anybody else stumble over this?

    Solved!

    Booted from Leopard install DVD again, waited 20 minutes, then played around with Disk Utility for a few minutes.

    Disk Utility couldn't see the partition either, but the disk started moving again (because Disk Utility was accessing it). That apparently made the installer read it (at last) and a few minutes later the partition was visible.

    Leopard is now installing.

    On my two Intel Macs it's already running fine.
