Hello,

I am on MacIntel running 10.5.4.

I have an external of 250 Gg connected via firewire.
On this external disk I have Tiger which used to serve me as a bootable drive in time I had G5. Now it is not recognized by the start-up function of my preferences pane, since, I assume, it is of G5 generation.

On this drive I have more than 200 Gg of backup, which I can't move elsewhere, so I can't formatted the disk.

When starting my Mac from the installation DVD of 10.5, and going on the menu, and after choosing the language, I am proposed where to install the 10.5, but the firewire is not available for installation, and the only place available to installation is my Harddrive, where I don't want any installation

How can I install 10.5 on this firewire?

TIA

The external is probably not partitioned in GUI format (even if it's one partition). If that's the case, there is no way to do what you want without a reformat.

(Disk Utility will tell you the partition scheme on the external.)

I think you mean GUID, not GUI.

Leopard will install to a APM formatted drive as well...it doesn't have to be GUID for an intel mac.

So, why I can't install the Leopard on this FW external disk?

The Leopard installer running from an Intel Mac won't install on an APM-formatted drive. It has to be GUID. Intel Macs can, however, boot from an APM-formatted drive, but system updaters (e.g., 10.5.1/2/3/4) should also disallow installation if the Intel Mac's boot drive is detected as APM.

You could always clone your Intel Mac's system to the external, but with the above caveat about system updates (unless you booted from the internal drive - GUID - updated that system, then re-cloned).

What a difference a letter makes.
