[SOLVED] PowerMac G5 unable to boot PPC ubuntu 7.10

[Chucklz15]

Hi all, I'm a bit new to the forums nad have a problem. I have a 2003 PowerMac G5 1.8 Dual Processor and was trying to install Ubuntu on it. When I put in the cd and hold the 'c' key it doesn't boot. So I go into the open-firmware and try the linux boot (boot cd:,\install\yaboot), sadly it doesn't work. I then try just the normal boot (boot cd) and it says LOAD-SIZE too small.

[mrsteveman1]

Is this a shipit CD or one you burned?

[Chucklz15]

It's one I burned, but when it varified it said it was successful.

[tiresia]

Why do you want to install Ubuntu 7.10?
I installed Hardy on my g5 and it works very well.
You can download it here:
http://cdimage.ubuntu.com/ports/releases/hardy/release/
You can choose the LiveCD or the alternate installer, both should work.
Burn it with the Apple Disk Utility (if you have Mac OS X) at low speed.
At the first prompt hit TAB and choose the option nosplash-powerpc64

[Chucklz15]

Thanks I'll try that tomarrow.

Chucklz

[Chucklz15]

OK I've downloaded it and tried to load it and it still says that the load-size is too small. (in open-firmware)

[Chucklz15]

OK, nevermind. I forgot to boot and hold the 'c' key :) Thanks everyone for your help.

[Chucklz15]

OK now i need help. I was able to successfully install ubuntu 8.0 on my mac but when I try to boot, it has this dos like console that says "press 'l' to boot linux or press 'c' to boot cd". When I press 'l' it goes to the second bootstrap and then the question mark with the mac icon appears again. Sorry to be a bother again. :)

Most probably is the configuration of yaboot not ok.
Start with your Installer-CD (if you used the alternate-CD choose at the first prompt the option rescue-powerpc64, if you used the Live-CD mount the HD where you installed Ubuntu just by choosing it in Places).
When you get a shell, or when you open a terminal, type in:cat /etc/yaboot.conf
You can post the result here.
Please tell us if you have on your g5 just Ubuntu, and where you installed it (/dev/sda3 maybe?)

[LBC_Nut]

I don't mean to hijack this thread but I'm having an identical problem on a PowerMac G4 (single 450 MHz CPU, dual 17.2 GB hard drives, and a stock ATI Rage128 video card) using ubuntu 7.04. Everything about this machine is original from the factory with the obvious exception of the OS. I expect the date of manufacture is ~2000, but can't say for sure. As soon as the download completes, I will reinstall with 8.04 and provide the results of the above command.

While trying to solve this problem, Google searching led me to
http://ubuntuforums.org/showthread.php?t=439629

Which led me to http://ubuntuforums.org/showthread.php?t=758301

I am afraid that I don't any prior experience with Linux or Unix and am not sure how to implement the patch recommended in post #8 if this is indeed the source of my pain.

Try at low speed!

OK I have done that in the console after I have mounted the HD but it says that the directory cannot be found. Maybe I also need to specify a drive in the command.

[Chucklz15]

OK I did some digging thinking that I can just navigate to the folder and I was right. Here is what was inside:## yaboot.conf generated by the Ubuntu installer
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.

## For a dual-boot menu, add one or more of:

[tiresia]

Ok, you may want to check the open firmware path of the boot-device
First of all back up your yaboot.conf
cp /etc/yaboot.conf /etc/yaboot.conf-backup
To determine the open firmware path of the boot-device
ofpath /dev/sda2
You should get something like:
/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0:2 (it is just an example!!!)
Edit your yaboot.conf
sudo nano /etc/yaboot.conf
Insert the ofpath after "device". It should look something like this
(again, it is just an example!!!)
boot=/dev/sda2
device=/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0:2
partition=3
root=/dev/sda3
timeout=50
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot

Save the changes (ctrl+X), say yes.

Run sudo ybin -v

Restart your computer

[Chucklz15]

OK the info on the device was correct, but when I do the last command I get this:
ubuntu@ubuntu:~$ ybin -v
ybin: Warning: no /etc/yaboot.conf, running yabootconfig to make one
yabootconfig: You are not root, go away
ybin: yabootconfig failed, please supply a valid /etc/yaboot.conf
ybin: You may also use ybin's --boot, --image, --partition, and --device switches
ybin: These switches will cause ybin to generate a basic yaboot.conf on the fly
ubuntu@ubuntu:~$


When I do the "ofpath /dev/sda2" command It just shows /disk@0:2.

[tiresia]

Sorry, I have forgotten to tell you to run ybin with sudo.
After you changed and saved yaboot.conf, runsudo ybin -v

[Chucklz15]

OK now I get this:
ubuntu@ubuntu:~$ sudo ybin -v
ybin: Warning: no /etc/yaboot.conf, running yabootconfig to make one
yabootconfig: unionfs: No such file or directory
ybin: yabootconfig failed, please supply a valid /etc/yaboot.conf
ybin: You may also use ybin's --boot, --image, --partition, and --device switches
ybin: These switches will cause ybin to generate a basic yaboot.conf on the fly
ubuntu@ubuntu:~$


It's almost like it cannot find the yaboot.conf or something.

[tiresia]

You must mount the device (as you have done before, when you used cat /etc/yaboot)!

[Chucklz15]

How? In the console? I already mounted it (by clicking on it in places).

[tiresia]

Can you please just runls /etc and tell us if you find your yaboot.conf

[Chucklz15]

It's not there, it might be looking in only the CD-ROM (called "File System") not the actual hard disk.

[tiresia]

I'm sorry, another mistake! Yes, of course, your HD is on /media.
Therefore, the file you must edit is also in /media/yourHD/etc/yaboot.conf

[Chucklz15]

I did and did the ybin thing again and it says this:
ubuntu@ubuntu:~$ sudo ybin
ybin: Warning: no /etc/yaboot.conf, running yabootconfig to make one
yabootconfig: unionfs: No such file or directory
ybin: yabootconfig failed, please supply a valid /etc/yaboot.conf
ybin: You may also use ybin's --boot, --image, --partition, and --device switches
ybin: These switches will cause ybin to generate a basic yaboot.conf on the fly
ubuntu@ubuntu:~$

[Chucklz15]

Maybe I need to tell it to look for the yaboot.conf in my drive rather than the one in the directory that they are trying to look for. The thing is I don't know how to do that.

[tiresia]

Let's recapitulate what you have done.
I assume that your Bootstrap Partition (where Yaboot is) is on /dev/sda2, and Ubuntu is on /dev/sda3, whose name is 'disk'

1. Start from the LiveCD

2. Mount the Ubuntu Partition ('disk') on /media (just by selecting it in the Menu Places)

3. Find the OpenFirmware Path of your Boostrap Partition (/dev/sda2) withofpath /dev/sda2

4. Edit the yaboot.conf of the Ubuntu partition, in order to add the OpenFirmware Path (device=)
sudo nano /media/disk/etc/yaboot.conf
Save the file

5. Now you must run ybin
sudo ybin -v -b /dev/sda2 -C /media/disk/etc/yaboot.conf


P.S. Do not mount /dev/sda2, otherwise ybin will not run
Do you want to install also MacOSX on your G5?

[Chucklz15]

Thats what I've been trying to do (but just install Mac OS X, not both). But the disk my friend gave me was no good (it was a backup or something) do you know where I can get a free copy or at leat a cheap one?

P.S. I don't know what you mean by the /dev/sda2, and /dev/sda3...I think that /dev/sda2 is my HD, I don't know. I just use the /media/disk but maybe I should try the /dev/sda3.

[Chucklz15]

OK I did the last code you posted with the ybin (I was trying to figure out how to tell it to look there) and here is what it said:
ubuntu@ubuntu:~$ sudo ybin -v -b /dev/sda2 -C /media/disk/etc/yaboot.conf
ybin: Finding OpenFirmware device path to `/dev/sda2'...
ybin: Installing first stage bootstrap /usr/lib/yaboot/ofboot onto /dev/sda2...

ubuntu@ubuntu:~$

[tiresia]

I don't know what you mean by the /dev/sda2, and /dev/sda3...I think that /dev/sda2 is my HD, I don't know. I just use the /media/disk but maybe I should try the /dev/sda3.

You have one hard disk. For Linux, it is a device (therefore /dev), its name is sda (if you had two hard disks the second hd would be sdb), and you have several partitions on it (sda1, sda2, sda3, and so on…)

When you install a Linux distro on a PowerPc Mac, usually you have at least four partitions on a hd:

1. /dev/sda1 Apple_partition_map
2. /dev/sda2 Apple Bootstrap (where yaboot, the bootloader is)
3. /dev/sda3 Linux (here Ubuntu)
4. /dev/sda4 Swap Partition

If you run fdisk -l /dev/sda, you should see a similar situation.

In order to access these partitions, you must mount the file system on it.
When you start your computer from a Ubuntu-LiveCD, Ubuntu mount a FileSystem on /media (with the name disk, disk1, disk2, and so on).

Please try to do just what I wrote in the post before. At least you can access your ubuntu system.

If you want to install MacOSX, you should do it before installing Linux. But we can try to find a solution for it, when you are done with the Ubuntu installation.
Have you already tried to boot the MacOs Installer-DVD, that you have (pressing C at boot)? When you are done, we can check this DVD, and maybe try to make it bootable if it is not.

[tiresia]

OK I did the last code you posted with the ybin (I was trying to figure out how to tell it to look there) and here is what it said:
ubuntu@ubuntu:~$ sudo ybin -v -b /dev/sda2 -C /media/disk/etc/yaboot.conf
ybin: Finding OpenFirmware device path to `/dev/sda2'...
ybin: Installing first stage bootstrap /usr/lib/yaboot/ofboot onto /dev/sda2...

ubuntu@ubuntu:~$

Well, you are done, try to restart your computer

[Chucklz15]

OK, I restarted and still no dice. It still starts the first stage bootstrap, I press 'l' and then it starts second stage bootstrap, then it has the mac symbol and question mark thing appear, I think we just reset the first stage bootstrap, not the second one (which we need to somehow fix).

[tiresia]

Can you please check all the steps I listed in the post #25?
Please check again the ofpath and be sure that you edit the file adding the correct ofpath. Can you please post the result of
cat /media/disk/etc/yaboot.conf

[Chucklz15]

Here (I even added the ofpath command to see if I put it in right):
ubuntu@ubuntu:~$ ofpath /dev/sda2
/disk@0:2
ubuntu@ubuntu:~$ cat /media/disk/etc/yaboot.conf
## yaboot.conf generated by the Ubuntu installer
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.
##
## For a dual-boot menu, add one or more of:
## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ

boot=/dev/sda2
device=/disk@0:2
partition=3
root=/dev/sda3
timeout=50
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot

append="quiet splash"

image=/boot/vmlinux.old
label=old
read-only
initrd=/boot/initrd.img.old
append="quiet splash"
ubuntu@ubuntu:~$

[tiresia]

Ok, the OpenFirmware Path you found with ofpath is not correct, because this command has a bug!!! Here is a link, where you can find more:
http://ubuntuforums.org/showthread.php?t=758301

Well, it is not so 'canonical', but you can try with this path (maybe we are lucky... add it to your yaboot.conf)
device=/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0

After that, run again ybin as you did before

sudo ybin -v -b /dev/sda2 -C /media/disk/etc/yaboot.conf

Restart your computer after that.

[Chucklz15]

So do you want me to replace the other ofpath or run this one somehow or what (how do you run it in the console without it being in the etc folder?)

P.S. I just tried your "device= %whatever%" and when I tried to boot (by pressing 'l') it did the little question mark and mac os symbol then it started to boot from cd-drive. I also read the post you lead me to, and I don't get it (I know that there is a bug and that there is a new version out). But I don't know what to do with it. I can't replace the old one because I don't have the permission (unless I do it with the console which I don't know how to do) nad I cant run it just on the desktop with root permissions.

[tiresia]

I was suggesting to try adding that openfirmware path to the your yaboot.conf.
But, since it is not so 'canonical' as I sad before, let's try another safer way(you must be a little patient...):popcorn:

Start your computer again and press immediately this four keys cmd+opt+O+F in order to access Open Firmware.
At the prompt rundevalias
You will see a list of all your devices and their open firmware path.
You must look for 'hd' (it is the alias for your hard disk) and its path.
It should be something like:
'device=/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0'
Note it (please pay attention to each details),
and run boot to start again the computer.
Press C to start from your ubuntu LiveCD and post the OpenFirmware Path to us.

[Chucklz15]

OH, now it makes sense, one second...

UPDATE: OK its:

/ht/pci@7/k2-sata-root/k2-sata@0/disk@0

[tiresia]

1. Mount your Ubuntu-HD (just choose your HD in Places)
2. Edit the yaboot.conf

sudo nano /media/disk/etc/yaboot.conf

After device add the open firmware path. it should look like this
boot=/dev/sda2
device=/ht/pci@7/k2-sata-root/k2-sata@0/disk@0
partition=3
root=/dev/sda3
timeout=50
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot

Exit and save the file

Run again ybin as before

sudo ybin -v -b /dev/sda2 -C /media/disk/etc/yaboot.conf

Restart the computer

[Chucklz15]

Still doesn't work, even after doing to the OpenFirmware to get the hard disk's thing.

[tiresia]

Are you sure that you copied the OF Path correctly?

Try to add to /media/disk/etc/yaboot.conf these two solutions, repeating the same process as before (run always ybin!)

First solution:
device=/ht/pci@7/k2-sata-root/k2-sata@0/disk@0:
(run ybin as shown above and restart your computer)


Second solution:
device=/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0:
(run ybin as shown above and restart your computer)

[Chucklz15]

None of them work.

[tiresia]

It sounds frustrating... I'm afraid that because of the mentioned bug we can't install a working yaboot. You may want trying the alternate install CD.
Here is the link:
http://cdimage.ubuntu.com/ports/releases/hardy/release/
Check it after downloading and burn at low speed.
Let me know, if it works!

[Chucklz15]

OK, I will try what you just suggested, but I think I have solved the problem. I know that there is a bug in the ofpath command and that there is a patch for it. But I cannot use the patch because of permission problems. I was hoping that you could supply a command that lets me replace the current ofpath from my drive with the one that I downloaded form this thread: http://ubuntuforums.org/showthread.php?t=758301 (page 1 from user "pxwpxw", link at end of his reply "ofpath.gz") Thanks for your help.

[tiresia]

I wanted to suggest you to do what you are right now trying to do, but I was afraid it is a bit annoying. Can you tell me, how are you triying to apply the patch?

[Chucklz15]

First off, nobody that I talk to for help has ever been annoying and why should you be if your helping me with my most hardest problem. Secondly I'm trying to replace the other ofpath with the patch one by just rewriting it. But I always get the "you do not have the correct permissions" pop-up. I was trying to do a copy command in the terminal but I don't know how (I'm only Windows savy).

Thanks

[tiresia]

Every command that changes your System must be run as 'super user'
Therefore you must use 'sudo cp'

If downloaded the ofpath.gz on your Desktop run
zcat Desktop/ofpath.gz > Desktop/ofpath
To copy that command
sudo cp Desktop/ofpath /media/disk/usr/sbin/ofpath

Then you can try to use it, in order to get the right Open Firmware Path
/media/disk/usr/sbin/ofpath /dev/sda2

Anyway, at this point you must really use the alternate install CD and at the prompt select the 'rescue option' (you do not need to install everything again!)
Then, when you are in your Ubuntu installed System, edit the /etc/yaboot.conf with the (correct) Open Firmware Path you got.
Run ybin.

[Chucklz15]

OK, I've copied the patched ofpath the the dir of my old one and still doesn't work. Now I'm trying the alternate disc.

[tiresia]

I added some informations in the post #46.

[Chucklz15]

OK, so I've replaced the ofpath with the instructions and the other patch that you gave me and when I ran the command it said the drive's full name (/ht/pci...disk@0). I put it into the yaboot.conf file and ran ybin. I restarted and it still doesn't work. Although now the ofpath is fixed so that's soething positive. But it's still not booting right. I think you said something about a bootstrap update (from 1.13.13 to 1.13.14 or something like that). Maybe that is what we need to do.

Thanks

[tiresia]

The problem is that when you run ybin from the Live-CD, ybin runs again the 'ofpath' command that it finds on the Live-CD (and that is buggy).
Therefore you got now a working ofpath, but you need to start it from inside the installed Ubuntu System. It means, that you need to change your Root Directory.
The easiest way is to download the Alternate install CD.
Here is the link (burn it at low speed!)
http://cdimage.ubuntu.com/ports/releases/hardy/release/

When you start (pressing C) your computer, at the prompt hit TAB
You will see several options. Choose:
'rescue-powerpc64'
After that you need to give some informations (it's extremely easy and faster then the Live-CD).

When you get to the question 'which device you want to use as root file system', choose /dev/sda3 (is where your Ubuntu System is).

You will get another question with several options, among them if you want:
1. to execute a shell in /dev/sda3
2. (ignore this one)
3. to install yaboot

Try first the third solution. If you are lucky, is the ofpath of the alternate install CD not so buggy as that one of the Live-CD and you will get a working Yaboot install on /dev/sda2.
Restart the computer and wait for yaboot.

If it doesn't work, get again to the same point like before, and choose the option:
execute a shell in /dev/sda3
At the prompt
check again that your /etc/yaboot.conf is OK. Run again:
ofpath /dev/sda2
cat /etc/yaboot.conf
and
ybin -v -b /dev/sdb2 -C /etc/yaboot.conf
(probably you do not need to specify these options, but let's be sure…)
Now you can start again your computer.
--
Can you please tell me if the open firmware path you get with the patched 'ofpath' is the same you got when you started with the Open Firmware.
Let me know how it works, so we can try to solve the problem with OSX

[pxwpxw]

The easiest way is to use your
option 1. to execute a shell in /dev/sda3 the installed ubuntu.
Then, if you have the good /usr/sbin/ofpath still intact in sda3
and you NewWorld bootstrap partition still exists, just run

yabootconfig --debug

from /dev/sda3,
that will rewrite yaboot.conf and the boot files all in one go,
and it should restart correctly.

If you take option 3, it will re-install the yaboot package and overwrite ofpath, and you are back to the start of the problem.

The other way was to put ofpath (pxw) on a usb stick and do the fixup in the initial install after the first part of the yaboot install, before ofpath is used by the installer, but that can be tricky.

[tiresia]

If you take option 3, it will re-install the yaboot package and overwrite ofpath, and you are back to the start of the problem.

Thanks pxwpxw, yes, you are right. I have read your useful post as well
http://ubuntuforums.org/showthread.php?t=896978&page=4
I tought that the alternate install cd could manage to find the right open firmware path.
(I know it not logic… But on the other hand is it logic that ofpath works well in several situations (for me it is ok) and it fails in other similar ones? :confused: )

[pxwpxw]

It depends on the apple model and the drive type, works fine for internal ide drive on ibook g4, not so for external or sata on some g5. All the ubuntu distros use the same version ofpath (buggy). The whole problem can be fixed by the revision when included in the yaboot package. Support the bug report if you agree.
https://bugs.launchpad.net/ubuntu/+source/yaboot/+bug/122607

[Chucklz15]

OK so I did the 1st option and did the yabootconfig --debug and now restarting (I did notice the last line after I ran the yabootconfig, I said "unable to determine OpenFirmware device name to /dev/disk/by-uuid/cbf, aborting..."). I don't know what this means but I will still try.

UPDATE: I finished restarting and still didn't work, when I exited the rescue disk there was a message box and it stated that the kernal in device /dev/sda3 loaded but had errors running, I will try again to see it it can fix itself.

UPDATE_2: I retried the rescue disk but the same thing happened, now what?

Thanks

[tiresia]

Can you please start again from your live-CD and do following:
sudo mount /dev/sda2 /mnt
Please, post me what you get from

Ok, I think it is missed up.
Anyway I would like to try following.
Restart your computer and stop it at the Open Firmware (cmd+alt+o+f)
The alias for your HD (coorisponding to '/ht/pci@7/k2-sata-root/k2-sata@0/disk@0') is 'hd', right?

If so, try first just
boot hd:,\\:tbxi

If it does not work, try:
boot hd/disk@0:2,\\:tbxi

Tell ma, please, what happens in both situations

[Chucklz15]

Situation 1: can't OPEN hd:,\\tbxi
Situation 2: can't OPEN hd/disk@0:2,\\:tbxi

[tiresia]

Just a question, before telling you my next proposal.
How many Hard Disks do you have?
Mac OS X is not yet installed, right?

[Chucklz15]

I only have one 320GB SATA disk installed on my computer and I would like to have Mac OS X on my computer, but I do not.

[tiresia]

Boot from your LiveCD (again...)
Mount your Ubuntu partition selecting it in 'Places'

Mount the proc, sys and dev file systems inside your Ubuntu install
sudo mount -t proc none /mnt/media/disk/proc
sudo mount -o bind /dev /mnt/media/disk/dev
sudo mount -o bind /sys /mnt/media/disk/sys

Chroot into your Ubuntu system:
sudo chroot /media/disk /bin/bash

Tell me what you get from
ls -l

UPDATE!!! (well not really): I was wondering I you could take control of my computer or something to help me do what needs to be done, or at least watch it and then tell me (guiding).

[tiresia]

Sorry, I made a mistake (I'm not used to mount a disk on /media).
Please, run
exit
and do again

Mount the proc, sys and dev file systems inside your Ubuntu install
sudo mount -t proc none /media/disk/proc
sudo mount -o bind /dev /media/disk/dev
sudo mount -o bind /sys /media/disk/sys

Chroot into your Ubuntu system:
sudo chroot /media/disk /bin/bash

Tell me what you get from
ofpath /dev/sda2

ubuntu@ubuntu:~$ sudo mount -o blind /dev /mnt/media/disk/sys

ubuntu@ubuntu:~$

there was a typo. you should be mounting to /media/disk/whatever instead of /mnt/media/disk/whatever

EDIT. Beat me to it.

Pre-note, UPDATE in my last post.

Ok now here:

No, I can't (and it would not be safe for you...)
Anyway, I hope we get soon a good answer from it

[tiresia]

Ok, run nowyabootconfig --debug and tell me what you get

[Chucklz15]

[tiresia]

Well, I'm not sure, if it works. Anyway, run
exit
umount /media/disk/proc
umount /media/disk/sys
umount /media/disk/dev
umount /media/disk/


Restart and try...

[Chucklz15]

Well all of them were not found anyway, and I think that matters.

[tiresia]

If you didn't restart, can you please tell me, what you see in :
ls /dev/disk

[Chucklz15]

root@ubuntu:/# ls /dev/disk
by-id by-label by-path by-uuid
root@ubuntu:/#


I'm going to have to finish this (I hope), a bit later. Going somewhere and will be back in about 4 hours.

[tiresia]

Ok, I go soon to sleep (I live in Berlin...)
My two last suggestions (for today): run, from the chrooted Ubuntu
mkofboot -v
and post it here.
If it should work umount everything, as explained before, and restart.


Second option:
If you can't yet boot, try again from Open Firmware (comd+opt+o+f) with following (please, note the difference 0 and 1) :

boot /ht/pci@7/k2-sata-root/k2-sata@0/disk@0:2,\yaboot
or
boot /ht/pci@7/k2-sata-root/k2-sata@1/disk@0:2,\yaboot
or
/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0:2,\yaboot
or
/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@1/disk@0:2,\yaboot

[pxwpxw]

If you want to pursue the yabootconfig way:

/dev/disk/by-uuid numbers should point to device names like this (for this box)

admax@g4:~/forum$ ls -l /dev/disk/by-uuid/

The by-uuid names should be links pointing to the sda partitions, but yabootconfig and ofpath are trying to interpret the uuid name (got from fstab) as device names which they need.

If there is some problem there, then an option is to give yabooconfig the bootstrap and root device name.

For example, (In your case -b /dev/sda2 -r /dev/sda3 I think)
I ran this as --noinstall for a test.

This would be done finally from the <chroot>/ with /proc /sys and /dev mounted as you have done.

And thats it, just run that command with the --noinstall? Or should I try tiresia's 4 solutions first?

UPDATE - IMPORTANT!!!: I did the ls -l /dev/disk/by-uuid command and this is what I got (I noticed that it didn't do sda2!!!!):

Hi Chucklz,

please, before trying my suggestiongs, try what pxwpxw suggests (me too i think is right)
You must be in the chrooted ubuntu (with /dev, /proc and /sys mounted)

sudo yabootconfig -v -b /dev/sda2 -r /dev/sda3

Please, tell me what you get.
If it doesn't work try my other solutions

[Chucklz15]

BINGO, YES!!! Your second solution seemed to have worked and I think I know why. I was looking around inside my computer and I noticed where my hard disk was located. It was in slot B, meaning slave, so in your second solution when you said "...sata@1..." it meant slave. Thanks everyone for your help.

[tiresia]

Right, I tought yesterday the same (because the patched ofpath gave a different path than that one you found days ago in the OpenFirmware - you have in fact seen the HD in slot A).
Now, from inside your new Ubuntu, you should anyway run (just to check that the command gives the same path that you used to boot)
ofpath /dev/sda2

and install a correct Yaboot

sudo yabootconfig -b /dev/sda2 -r /dev/sda3 --debug

Please, if your g5 is now ok, mark the thread as solved
:)

[Chucklz15]

How do I do that exactly?

UPDATE: Everything matchs what I booted with and the yabootconfig is working.
