I personally have use with GUID + EFI.

GUID is more improved than MBR, for example one can make & edit partitions without loosing / having to delete data!

Here's how to fix MBR boot without EFI:

// rdiskXsX: you have to know the proper partition names and replace them with X.
In my case, it would be rdisk0s1, first HDD, and first partition, on which leopard has been installed,
which you need to make bootable. You can also check this in the Disk Utility.

Hit enter after each terminal line to execute the command. //

1 -> Launch DVD
2 -> At boot prompt, type -s (single user mode)
3 -> Type:

fdisk -e /dev/rdiskX
update
f 1
w (yes)
q

4 ->
cd /usr/standalone/i386

./startupfiletool -v /dev/rdisXsX ./boot (X is your partition)

5 ->
mount -uw /
mount -t hfs /dev/diskXsX /Volumes

6 ->
bless -device /dev/diskXsX -setBoot -verbose

7 -> reboot, without any dvd inserted.

i will try the MBR fix now, before i reinstall to GUID again. just to know if its work. BUT: MBR without EFI... hmmm EFI is a must in the MAC world or isnt it? for smooth internet updates etc. or am i wrong?
(AFAIK i installed MBR WITH efi on my hdd usb2.0 ide 2 weeks before.)

Revision 1 doesn't have EFI included, so you most likely haven't installed it, unless you followed a Guide to do so!!

Rev.2, which is not yet released to public, is meant to be installed as GUID + EFI, I guess.

EFI is not a must, but it's an improvement for the system.

Better Performance and stability because of apple stock kexts, everything runs very smooth, working system updater etc.

Actually without EFI I had nice system performance, but with EFI it's just as smooth as a real Mac.

5 ->
mount -uw /
mount -t hfs /dev/diskXsX /Volumes

device busy

skipped step 5 and rebootet after everything now i have "still waiting for root device"

Is your Leopard Harddrive mounted as Master? What does your BIOS tell you when booting?

xan · #17 01-30-2008, 08:11 PM

i have sata! no master / slave anymore. everything should be master
as i did the step by step, my leopard was the disk1s1
i have also a 2 other satas. the other one is disk0 and disk2

now i will install leo with GUID - then i will do the first step by step for GUID+efi

Puttabong · #19 01-30-2008, 08:20 PM

xan, am I wrong? Sorry, is EFI actually already included in rev.1, as well?
I don't think it is. I thought if you use RC1 then you will have to install EFI manually!

This is how to install EFI to use it with GUID for RC1/Rev.1!

Get a copy of pc_efi_v80 and save it to a FAT external harddrive / pendrive

Quote:

boot with the dvd

open a terminal and type

diskutil list

diskutil unmount /dev/diskXsY

cd /volumes/"YourVolumeNameHere"/pc_efi_v80

umount -f /dev/diskXsY

./startupfiletool /dev/rdiskXsY ./boot_v8

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

diskutil unmount /dev/diskX

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

Here's another tutorial for EFI, which works for amd AND intel:

I suggest that you use MBR with Rev.1, until the second Release is available! It's a lot easier.

It won't take very long until it is released to public, and it has EFI and many fixes included for an easy installation!

is it normal, that after GUID installation that i have 2 partitions on the hdd?
1 200MB EFI partition
2 40GB Leopard partition ?
