    So much for upgrading... Does anyone have a fix for not having a GUID partition table scheme? I was hoping I wouldn't have clean install, I just got everything how I wanted it. *sigh*

    Something tells me there's no way around this.

    Use SuperDuper's free version to clone your disk to a backup drive, boot off that and use Disk Utility to reformat your primary drive using GUID, use SuperDuper again to clone it back, and then upgrade...

    You can edit OSInstall.mpkg in your SL installation to install on MBR partitions.

    I am having the same problem. I'm backing up my hard drive via time machine to external usb drive. Then I'm gonna reformat and install SL, and finally clone back.

    This has already been successfully accomplished.
