[How to] Dual Boot VISTA/LEOPARD, same HD over GUID+EFI V8
 

"How to" dual boot Leo (AMD) / Vista (GUID + Efi V8 the same HDD)

-You need.

-A pendrive labeled "EFI"
-Install DVD (leoapard Zephyroth)
-Install DVD (Vista 32/64)
- Efi pack ( Extract the efi pack to the root of your pendrive)


1. Boot into Leopard install dvd and open disk utility, click your HD you are makeing a Guid then click the partition tab click the drop down menu and select the number of partitions that you need, in my case i have used two, the first one for VISTA( Fat32), the second one for LEOPARD (Mac Os Extended (journaled)) then click options and select GUID, aply and reboot when it´s finished.

2. Boot into Vista install dvd and when you see the screen of disk selection, click the patición in fat32 and format in NTFS, then install Vista.

3. When vista finishes, boot into leopard DVD and install over the partition that you have created in the step 1. When Leopard finishes, reboot again into leo dvd plug the pendrive labeled "EFI" and open a terminal and type this:

diskutil list

You´ll see something like this



cd /volumes/efi/pc_efi_v80

umount -f /dev/disk0s3

./startupfiletool /dev/rdisk0s3 ./boot_v8

dd if=./guid/boot1h of=/dev/rdisk0s3 bs=512 count=1

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



reboot and that´s all, you don´t need touch the Vista bootloader you´ll see Darwin with those options

- 1. hd (0,1)
- 2. hd (0,2) Foreign BOOT (VISTA)
- 3. hd (0,3) LEOPARD


Enjoy...

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

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"

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

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

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

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

try over MBR

diskutil unmount diskX

cd /volumes/efi/pc_efi_v80

./startupfiletool /dev/diskXsY ./boot_v8

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

lol

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

Can this be used for OSX/UBUNTU (linux) ?

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

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

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,
zenpath :)

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...."

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! :)

Oh ... my eyes. ... I need glasses ;-)
Thanks, I'll try. Will be back in a second ...

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

I am sorry, maybe your board is not compatible. :(

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

wait to the rev2

Mh... alright. Thanks roisoft.

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

Look at the blog of our <a href="http://netkas.org/?cat=5">master netkas</a>.

Vista won't let me install to a GUID partition, even with service pack one slipstreamed on the disk, any ideas?
