Extremador Posted June 12, 2008 Share Posted June 12, 2008 Hi, I just installed Leopard using Leo4All v3 onto my newly bought 320GB external hard drive and everything went perfect until when I tried to boot it up with the "tboot" thing, it just told me there wasn't a HFS+ partition (when there clearly was one). How do I boot from my external hard drive? Thanks a bunch!

cgsheen Posted June 12, 2008 Share Posted June 12, 2008 Best go to the leo4all wiki... Your fix will depend on what bootloader you tried to install (what partition format you used - GUID or MBR) Link to comment https://www.insanelymac.com/forum/topic/110088-booting-leopard-from-external-hard-drive/#findComment-780391 Share on other sites More sharing options...
Extremador Posted June 12, 2008 Author Share Posted June 12, 2008 I tried to find this in the wiki but had no luck. It's a MBR right now. I read in that "Boot OS X from a thumb drive" thing that to make the flash drive (or external hard drive) bootable you have to go to terminal and input "sudo bless –verbose –folder “/Volumes/iTote/System/Library/CoreServices” –bootinfo" but in MY terminal it's like "bash#3.2" and when I put the "bless" thing it says I need to run it from an installation CD or something like that. Is iATKOS easier than Leo4All? Link to comment https://www.insanelymac.com/forum/topic/110088-booting-leopard-from-external-hard-drive/#findComment-780979 Share on other sites More sharing options...
cgsheen Posted June 12, 2008 Share Posted June 12, 2008 If it's MBR it's simple - you HAVE to know the disk number and partition number though! Boot with the install DVD At the "countdown" press F8 (for startup options) At the prompt type -s (this will put you in "single user mode") - it'll load some stuff and dump you at a command prompt - at the command prompt type: fdisk -e /dev/rdisk0s1 (hit Enter) - NOTE: THIS is where you HAVE to know the actual disk number and partition number (if you have other disks connected and you use the wrong number, you've just screwed up one of your other disks! The above example (rdisk0s1) assumes disk "0", partition "1" - CHANGE the numbers if you installed to disk 2, partition 2 ( /dev/rdisk2s2 ) update (hit Enter) ( updates the MBR ) f 1 (hit Enter) (Makes the partition active - USE the ACTUAL partition number (see above)) w (hit Enter) (writes the MBR to the activated partition from above) q (hit Enter) (quits the fdisk utility, saving changes) reboot (ya, hit Enter...) (what do you think this does...) Pull the DVD and, if everything went properly above, it should now boot off the HD...

Extremador Posted June 12, 2008 Author Share Posted June 12, 2008 Okay I'm gonna try this but just so that I DON'T fux up my other disks, do I get the partition/disk number in "Disk Utility"?

knibble Posted June 12, 2008 Share Posted June 12, 2008 yep. hard drive numbers start at 0 and partitions start at 1. Link to comment https://www.insanelymac.com/forum/topic/110088-booting-leopard-from-external-hard-drive/#findComment-781252 Share on other sites More sharing options...
Extremador Posted June 12, 2008 Author Share Posted June 12, 2008 I did everything you said there but "w (hit Enter) (writes the MBR to the activated partition from above)" didn't work using the command prompt BEFORE booting up into the installation screen...HOWEVER I was able to do it from the terminal after starting up. Anyways... the way I boot into the installation thing is when I get my splash screen I press TAB, then F11 (boot options), then CD-ROM and it has the countdown thing. When it reboots after I do the "reboot" in terminal or the other thing, I have to do it all over again and then it just goes back to the same place...where my only options are to continue of hit F8 and enter that command prompt thing. What the heck am I doing wrong? BTW it's rdisk4s1 for me.
