On an older Mac it would require access to some source code and to modify the code for boot.efi there. It doesn't make much sense to store a dmg on an HDD, mount it and boot from it, instead of directly saving the content of the dmg to a HDD volume and booting into it. – klanomath Jul 25 '17 at 3:57.

10.4: Create a single Universal binary bootable disk
I just ordered a 120GB 2.5' drive for my little Firewire case so that I can do this same kind of thing. I currently have a drive with a partition with the original Tiger install disk on it (so I can install from a hard drive instead of DVD), a partition with Tiger Server install on it, and a repair disk which I can boot off of and perform tests and maintenance with. With the bigger drive I hope to have a Tiger PPC Install partition, Tiger Intel Install partition, Tiger Server Install partition, a Universal repair disk partition, and a catchall partition with all the Software Updates and other programs and stuff that I put on computers. Since I own a copy of SuperDuper, I'll probably true to use it to build the Universal boot partition instead of Carbon Copy Cloner since it can update a disk image much quicker with only the differences.

10.4: Create a single Universal binary bootable disk
A word of caution using SuperDuper! in this application - It adds AND deletes files not on the 'original'. I tried to SuperDuper my server drive (from drive 'A' to drive 'B'), but didn't want to take the time to copy ALL the user folder's files so I left them out. Then when I wanted to bring the system back to how it was when I used super duper (smart copy from drive 'B' to drive 'A') it deleted all the user folders on the server that I had left out! Because they weren't on the backup. There maybe a setting to allow this, but I just wanted to let you know about that scenario.
Otherwise a GREAT hint with a niche application.

10.4: Create a single Universal binary bootable disk
Anyone suppose there would be any downside to performing this process with tiger server as the PPC install, and then cloning the intel client install on top of it. I'm trying to figure out how to best integrate a mac mini dual core into a multi-computer home environment and having access to the portable home folders on tiger server would be ideal. Its hard to see where the pitfalls might be, but its worth a try I think.

How To Make Mac Os Bootable Usb
It's very unlikely this would work beyond just getting you a universally bootable system.
it's likely that some of the Mac OS X Server-specific components would be broken, and you wouldn't be able to (easily) update to, for example, Mac OS X Server 10.4.6 when it comes out (whereas you could use the Intel client updates on a non-Server installation, since all of the Intel updates are universal).
You're better off waiting until there's an actual Intel version of Mac OS X Server as well, at which point you'll still have to jump through all these hoops to make a universal installation.

10.4: Create a single Universal binary bootable disk - usb vs firewire
this is a great workaround for a universal system until apple fixes this in leopard (and so many other tiger gotchas).
but one note of frustration regarding the boot drive -- unless one is willing to have a bulky 3.5' device to lug around, a 'mobile' a formfactor is the most practical approach.
but for some silly reason, none of the 'mobile' devices (2.5' winchester & slim dvd burners) are not avail with combo (usb/fw) interfaces. The oems force you to choose between only fw or only usb!
of cousrse we all know (but cant fathom) why apple dropped support for usb booting on ppc macs (avail in classic but not in osx); so that leaves fw as the only way to boot macs x-platform.
but the penalty for this arbitrary limitation on boot interfaces is that a precious fw port is consumed on the host machine - which are in short supply on new macs (part of apple's bizzare campaign to destory the viability of fw - eg on ipods); and fw is not widely avail on pc's, so one is sort of stranded (or saddles with extra gizzmos) if one picks a fw-only boot solution.
It would be so sweet to see 'mobile' dvd & 2.5' harddrives come with both ports (usb2 fw400 & fw800) ...
... while we are at it, a SATA & ethernet/NAS port would make great sense as well!
(not to mention IR & BT ports to be able to 'tunnel' in support for RemoteControl/FrontRow, but that's another story ;-)

10.4: Create a single Universal binary bootable disk - usb vs firewire
There are many manufacturers of 2.5 drive enclosures that sport both USB and FireWire, Lacie being one of them. Of course, you'll pay a bit more to have to daul interface but in my opinion, it's well worth the cost.
10.4: Create a single Universal binary bootable disk - usb vs firewire
OS 10.4.6 (and maybe one or two earlier point versions) and later WILL boot from a PPC Mac's USB port--Apple apparently relented. One limitation: You can't select it for booting in the Startup Disk Prefpane (it will just beep at you)--you have to select it from the Startup Manager, which you invoke at startup by holding down the Option key right after powerup or restart. I've confirmed this works on a slot-loading 350 MHz iMac that didn't even have Firewire ports. The iMac's firmware was version 4.1.9 (which it needs to be anyway, to allow OS X to work on the slot-loading iMac). I didn't test USB OS X booting on an even older, tray-loading iMac, nor did I test booting from a 2.5' USB drive enclosure, nor did I test USB OS X booting on the last of the PPC Macs, so I don't know what the story is there.
10.4: Create a single Universal binary bootable disk
There is an important drawback to this suggestion. Not everyone has both PPC and Intel copies of the same version of OS X. For example, my Tiger DVD has version 10.4. My MacBook Pro DVD has 10.4.5. I would have to do full installs of each version, updating the PPC version via the Combo Updater. But now I don't have a universally bootable installer.
10.4: Create a single Universal binary bootable disk
Personally I would rather keep the two partitions separate so I can update both further down the track when new hardware requires a new OS. We have about 10 dual bootable FW drives all running 10.4.5, when 10.4.6 is released I will apply the PPC/Intel combo updaters to all drives and any new hardware (ibooks etc) released soon, will be supported by those drives, without having to re-image.
IMHO, a better way to do it long term until a true universal is released.

I used a 15' G4 PowerBook and a MacBook Pro on this and at the end the PPC laptop booted, but could not load the Finder correctly.
Perhaps I did something wrong, but it seems that I might hold off on this for Leopard and just bite the bullet unless there was a step above that I missed; below is my process (in Wiki form ;))

My backup system involves mirroring the entire disk of my PowerBook G4 from time-to-time onto an external FireWire disk (Apple Partition Tabel format) using Carbon Copy Cloner, and daily backups (with history) using the fabulous rsnapshotx. So in case the internal disk dies, I can boot off of the external disk and continue.
The PowerBook is now replaced by a MacBook Pro, and I wanted to make the system (and backup) a Universal OS X as described above, so that in case the MacBook Pro dies, I can as a backup still use the PowerBook (booting from the external backup drive). Sounds quite useful. :-)
As the MacBook is my production system, I wanted to know what files are actually merged into the Intel System to make it (supposingly) universal. So this is what I did:
1) Install Intel-OS X on MacBook Pro and make all updates (10.4.10).
2) Install PPC-OS X on external FireWire drive (I could have also done this onto the internal PPC disk, but I still need what is there at the moment). Also make all updates (10.4.10).
3) Hook external FireWire drive onto MacBook Pro.
4) Find out what files are in the PPC-OS X installation that are not in the Intel-OS X installation:
sudo rsync --dry-run --ignore-existing --extended-attributes --verbose --archive --max-delete=0 /Volumes/LaCie PPC/ / > rsync.log
The plan was to remove the '--dry-run' part of the above command to copy all missing files into the Intel-OS X to make it universal (without overwriting anything that is already there).
However, the above command shows that the number of PPC-only files that would be merged into the Intel-System is around 53000 (!!!). These files are all-over the place (Applications, Library, Systems, CoreServices, ...).
I decided to not to proceed further (I need a reliable production system and can live without the unversal boot), so I cannot confirm if this would work or not.
However I conclude that the differences between an Intel and PPC OS X are not only a few missing drivers (as suggested in the references cited in the original article), but a large number of files at numerous locations.

If you’re still using a Mac OS X the time will come when your computer won’t boot, or a problem may arise where you can’t take control of the device, and booting from an OS X installation media will be required.
This is why it’s recommended that you make a Mac OS X bootable USB when your Mac is in working conditions. However, if you find yourself on a scenario where your device (iMac, MacBook Pro, Air, Mac Pro or Mini) is not responding and you happen to have a Windows device, then you can still be able to make a USB bootable installation media for your Mac OS X to reinstall the operating system using the Recovery Assistant.
These instructions will also work for Windows users, who are running Mac OS X on a virtual machine and need to upgrade to the latest version. For instance, to OS X Yosemite.
Things to know before proceeding
Before you dive into this guide, you’ll need a few things:
- A broken Mac computer with Mac OS X.
- A trial copy of the TransMac software.
- One high quality USB flash drive with 16GB of storage.
- A copy of Apple’s macOS (DMG file).
Now that you have all the necessary ingredients, you’re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below.
How to create Mac OS X bootable USB installation media
Before you can use TransMac, you may first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows.
Setting up GPT partition
Use these steps to set up a USB drive with a GPT partition:
Download Bootable Mac Os
- Open Start on Windows 10.
- Search for Command Prompt, right-click the top result and select the Run as Administrator option.
- Type the following command to open Diskpart and press Enter:
- Type the following command to determine the USB flash drive and press Enter:
- Type the following command to select the storage and press Enter:Quick tip: The
select disk 1
command as an example, but you have to replace 1 with the number of the flash drive you want to use. - Type the following commands to delete everything from the USB thumb drive and press Enter:
- Type the following command to convert the drive into a GPT partition and press Enter:
- Type the following command to select the new partition and press Enter:
After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.
Creating USB install media
Use these steps to create a bootable media to install Mac OS X:
- Download and install a copy of TransMac.Quick note: TransMac is a paid software, but it has a 15-day trial solution, that give us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)
- Insert the USB drive that you’ll use to fix your installation of OS X. (Remember that all the data in the USB will be erased. Make sure you take off any important documents.)
- Right-click the TransMac software icon and Run as administrator. (You’ll be prompted to Enter Key or Run, because we’ll be using it once, click the Run option.)
- On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive that you’re intending to use to reinstall Apple’s OS X and select the Restore with Disk Image option.
- In the warning dialog box, click the Yes button.
- Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system.Now, you’ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.
Once your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option key, and select the USB you just created to reinstall Mac OS X.
If you’re having issues trying to create a bootable media, you can get a USB flash drive that comes with Mac OSX ready to install.
