Dual Boot VISTA/LEOPARD, same HD over GUID+EFI V8

open a terminal and install efi again, you must unmount the disk, that is the most important thing.

diskutil unmount /dev/"all the partitions"
umount -f /dev/"leo partition"

Boot over install DVD, plug your pendrive and open a terminal and try this

diskutil list (take note of your device)

cd /volumes/efi/pc_efi_v80

diskutil unmount /dev/diskX (X=device)

umount -f /dev/rdiskXsY (X=device Y=leo partition)

dd if=./guid/boot0 of=/dev/disk0 bs=400 count=1

reboot

if you only want a Mac Os, boot over install dvd, choose a guid partition scheme when the install finishes boot over the install dvd again open a terminal and install efi

please, post your hard..i don´t remember

try over MBR

diskutil unmount diskX

cd /volumes/efi/pc_efi_v80

./startupfiletool /dev/diskXsY ./boot_v8

I only have SATA HD, i don´t know if with ATA disk works.

I have never tried it, maybe with rEFit, you can try it and post your results here.

that´s the problem man!

Try this

open a terminal before the last step "dd if=./guid/boot0 of=/dev/disk0 bs=400 count=1" unmount all the partitions, then again "umount -f /dev…"

i tried installing efi with rev1 but i get "b0 error." when trying to boot into leo, any ideas?

still not working, same error
edit: can i install efi using this method without having vista installed? (i want to give up windows permanently)

with efi i get "still waiting for.." without efi its works... any other ideas?

40 GB seagate ATA, i tried MBR i got the b0 error, i tried again GUID after instaling efi i got hfs+ partition error =))…i think my PC has AIDS or something

just wanted to say that EFI work on ATA ... the partition wasn't erased properly thats why i got those errors

A little question: I couldn't use the "unmount"ing when installing EFI (unknown function or similiar), so I skipped it. I can't execute the last command:

dd if=./guid/boot0 of=/dev/disk0 bs=400 count=1

It says: Ressource busy

crawle, Use the Disk Utility to unmount all Leo Partitions - for example if you have a partiton on a disk, don't only unmount the disk, but also the partition! Then execute the command again!

Kind Regards,

So what should I do first? I think, I didn't understand you right, excuse me.

BTW: just "unmount -f ..." doesn't work. Only "diskutil unmount" works, but without the flag.

umount -f /dev/diskXsX

Not only umount -f, and not unmount -f, but exactly like written above!

Alright. It worked.
So I rebooted ... and ... "System config file 'com.apple.Boot.plist' not found. ...
Any idea?

Oh, it's a pitty. So is there no way to install Leopard?

Please share the EFI Pack. I can't find it anywhere
