    Hi there folks!

    I'm having a problem where Lion OSX 10.7.2 doesn't show up the different existing boot partitions.

    I have 2 partitions in one disk and 2 partitions in other disk:

    Primary Disk:

    · Partition one: Lion OSX 10.7.2
    · Partition two: Snow Leopard OSX Latest Version.

    Secondary Disk:

    · Partition one: For storage in OSX Format.
    · Partition two: Bootcamp for Windows 7 64 bits.

    Bootcamp version: 3.3

    For some very strange reason, Lion doesn't recognice the Bootcamp partition, therefore, it cannot be mounted, as shown in the image below:


    It doesn't also, recognice it in the Boot Disk Selection as shown in the image below:


    The weird thing is that all the boot partitions are recognized by Snow Leopard (when booting from there) and also, by the Bootcamp Control Panel in Windows 7.

    The next 2 images shows it:

    Snow Leopard:


    Windows 7 64 Bits:


    So I'm wondering why they're not shown in Lion!

    Any help/tip will be grately appreciated because I have to jump into SL if I want to go to Windows.

    Thanks so much for your help!

    Ø3 :)

    Could it be Lion uses Bootcamp version 4 and Snow Leopard version 3.x?

    mmmhhh... I didn't know about bootcamp 4! Bootcamp didn't told me about a new version! Will take a look into that!

    Thanks a lot!!!

    Mine doesn't show up either (well it never showed up).

    Just hold the 'Option' key when booting up and you should be able to switch as needed.

    Yes, I knew about that, but since I have installed a video card which is not "officially" for the Mac (ATI 5850, another one for the list:D), I have not access to the boot screen.

    Your help is very appreciated! Thank you :)

    Ø3 :)
