    Then, boot up holding OPTION and it should give you a screen asking which system you want. :)

    yep, partitions ...

    Works great for upgrades on a work machine, always wait until you know a version is stable before upgrading the backup.

    That way if there is a problem, you can always revert to the copy of the OS you know will work.

    oh ok. for some reason i thought bootcamp put some kind of bootloader on your hard drive. i guess that's something different
