vaporATX Posted February 20, 2008 Share Posted February 20, 2008 I duped my main OS X drive with Superduper 2.5 to a partition on a sercondary drive. Now I know I have to install pc_efi on this partition so I can boot off of it, and I can't for the life of me figure out how to do it and have the Darwin bootloader pick it up. I've been seraching all morning for info, and I know it's there... maybe I'm too brain fried to be doing this right now. A kick in the head would be much apreciated.

superjunaid Posted February 20, 2008 Share Posted February 20, 2008 I had the similar issue, what I did was boot from the OS X DVD, made sure that the EFI folder was on my USB Flash stick. Once the installer loaded I launched the Disk Utility from the tools menu, unmounted the drive in question, noted down 2 important things 1. device info i.e. rdiskXsY (where X is drive, Y is partition) 2. if it was GUID or MBR. Exit Disk Utility, go into Terminal and browse the folder for EFI\pc_efi_v80 once you are in the folder where the startupfiletool is located (check via ls) run the following command for MBR ./startupfiletool /dev/rdiskXsY ./boot_v8 (Enter) use the following command for GUID ./startupfiletool /dev/rdiskXsY ./boot_v8 (Enter) dd if=./guid/boot1h of=/dev/rdiskXsY bs=512 count=1 (Enter) dd if=./guid/boot0 of=/dev/diskX bs=400 count=1 (Enter) Once this is done, you may now proceed to boot your system from your cloned drive. Good Luck!

vaporATX Posted February 20, 2008 Author Share Posted February 20, 2008 Yeah, now I remember! Thank you, man! It's embarassing when you installed your system using that method, but you just can't make your brain work. That's what spending all last night doing a flippin' 40 workstation Vista roll out for a customer who you advised not to do it will do to your brain. My poor assistant was ready to choke down a revolver by about 4 am. Redmond needs an Airstrike. Thanks again!
