    Hi everyone. First post, let's hope it goes well.

    Obviously looking forward to the Lion release that hopefully is on Thursday the 14th, and I tested the GM along with a lot of people.

    I was hoping I could pick your collective brains.

    Do you think it would be possible to make a second partition, copy all the stuff I want to keep from my existing Snow Leopard Drive to it, then perform a clean Lion install (the boot disc method), copy everything back and then remove the second partition and expand the Lion one?

    I see no reason why not, but if anybody has a reason, I'd like to know.

    I did this and for some reason Lion refused to be expanded.

    Ok, thanks, do you think I would be able to expand it from Disk Utility on the Lion (or Snow Leopard) install disc?

    I could be wring about this (someone please correct me) but it was my understanding that for a partition to be deleted [lets say "Snow Leopard"] AND then its space recovered into another partition, the partition to be deleted needs to be AFTER the partition to be expanded [lets say "Lion"];

    This works fine when you install Lion onto a blank disk and Lion's Recovery partition is installed after the base partition that Lion is installed onto; you have the ability to delete the recovery partition and then expand the base Lion partition to recoup the lost space.

    I too have had issues expanding a partition with the space reclaimed from a deleted partition that appears in front of the partition that I want to expand.

    In that case, it should work fine. I have the backup partition I made, after the main Macintosh HD. The Macintosh HD will be wiped and Lion installed on it, hopefully not touching the Backup partition. Since the backup is after the Macintosh HD, I should be able to delete the Backup partition and expand Lion (Macintosh HD) into it. Right?
