    Hi I tried to delete lion gm partition with disk utility and it said, "This operation requires a newer version of mac os x for this disk"

    Anyone know how I could remove lion gm partition?

    boot from the lion recovery drive or another lion boot disk and you can delete it

    Wouldn't booting from any Mac OS X disk work, too?

    I got the same error.

    I guess, i would have to wait for the official Lion OS. Will update then and will go back and delete this beta Lion partition.
