http://forum.insanelymac.com/lofiversion/index.php/t68453.html Set your Leopard Partition to "active" and create a Boot Loader. This is the way to create/repair MBR and boot loader after you do the Post-Installation Patch. This is how to do it: Step one: 1. Boot to Tiger Step two: 1. - Download "Startupfiletool" - it can be found in this thread http://forum.insanelymac.com/index.php?sho...mp;#entry166040 2. - Unstuff and place "Startupfiletool" in "usr/sbin" the easiest way to do this is to press shift-cmd-g in Finder and enter "/usr/sbin" - then drag the "Startupfiletool" into the "sbin" folder 3. - Locate and open the folder "files" on your Desktop (it's one of the folders from BrazilMAC's patch folder) - inside "files" is a folder called "i386" - open it. - press shift-cmd-g in Finder and enter "/usr/standalone/i386" then drag all files from the first opened "i386" folder (the one on desktop/files) into the "i386" folder 4. I'm not 100% certain of tis, but I believe you may also need to put "bless" into "usr/bin" (it can be found in the patch files on "desktop/files/") Step three: 1. Open Terminal 2. - Type: "diskutil list" result will show all your partitions - Write down volume name and disk identifier info! Example: name: Leopard identifier: disk1s2 (1=disk number 2=partition number) I will use "disk1s2" (or "rdisk1s2") and "Leopard " in this guide code! - exchange it to your correct numbers and name when you see type in the code!!! Step four: 1. Mark the partition active - Type: "sudo fdisk -e /dev/rdisk1" (exchange "rdisk1" to your correct disk number!) - enter your password - Type: "update" - Type: "f 2" (exchange "f 2" to your correct partition number) - Type: "w" answer the question with "y" - Type "q" Step five: - Type: "diskutil unmount /Volumes/Leopard" (exchange "Leopard" for the correct name of your Leopard partition!) - Type: "sudo dd if=/usr/standalone/i386/boot1h of=/dev/rdisk1s2 bs=512 count=1" (exchange "rdisk1s2" for your correct disk and partition number!) - Type: "sudo startupfiletool /dev/rdisk1s2 /usr/standalone/i386/boot" (exchange "rdisk1s2" for your correct disk and partition number!) - Type: "sudo bless -device /dev/disk1s2 -setBoot -verbose" (exchange "disk1s2" for your correct disk and partition number!) - Type: "diskutil mount /dev/disk1s2" (exchange "disk1s2" for your correct disk and partition number!) - Type: "bless -mount /Volumes/Leopard -setBoot -verbose" (exchange "Leopard" for the correct name of your Leopard partition!) You may get an error "Could not find IODeviceTree:/options" but it works! Step six: Boot Leopard
