Youll need access to a DVD drive somewhere so that you can make a disk image of the Snow Leopard install disk with the Disk Utility tool, but once you have the disc image you wont need the DVD drive again.

What you WILL need the entire time though is an external Firewire or USB drive that you dont mind formatting, so that you can make the device bootable and upgrade to Snow Leopard from it.

If you do need to, you can create a DMG file of the Snow Leopard disk, this is very easy.

I manually set the boot by bless command but still nothing happened.

Is this normal, or did something definitely go wrong My files all seem to be there and my applications are running fine so far, I just have no idea where all of that free space could have come from.

Most PPC will ONLY boot from a FireWire drive, and select Apple Partition Map instead of guid.

Requires you doing a fresh install at some point of Tiger or Leopard before updating to Snow Leopard.

I happened to have just done a fresh install a few weeks ago.

It requires partitioning a small portion of the Mac hardrive so you have a 10 GB partition setup as explained in the above tutorial.

Then after you have created a DMG of Snow Leopard and have it saved to anywhere(desktop) is what I do.

In disk utility on restore just set the dmg as source and drag your new 10gb partition as destination.

I think you should have mentioned that in your initial post.

No need to make an image first you can go straight from the dvd if you dont have an image.

Double click to it (it will mount it) Select the mounted volume (below your dmg file) Right click (CtrlClick) Select Set as source Important: Select the mounted drive as source, and NOT the dmg image After it, select the destination image.

And click restore.

It will ask about erasing (I recommend it, if you dont have important data on the drive, anyway it may not be boot), so click yes, if its possible.

Now that its so easy to install Mac OS using an external drive though, is having a DVD drive really a good usage of limited hardware real estate on your.

The source image needs to be imagescanned before it can be restored Any help is appreciated.

The Hard Drive itself can only have one set of disc drivers, no matter how many volumes you create on it.

The choice of Apple Partition Map Scheme or Global Unique Identifier (GUID) is decided once for the entire Hard Disk Drive.

Intel Macs Boot from GUID and PPC Macs use APMS.

On Intel Macs it is possible to boot from the disk image of Snow Leopard Installer.

If the disk image is on an external drive and you launch the installer app within the disk image, then your Mac will attempt to boot from the disk image.
