booting from usb external drive

Trying to fix my old PowerBook G4. I found my internal hard drive is dead.

I'm trying to reinstall the Mac OS-X but doesn't find any drives.

I attached an external USB drive (to try to install the software there) but doesn't find it. When I open disk repair, the external drive is there (the internal drive doesn't show)...

Any suggestions? Can I install the operating system in the external USB and boot from there?



Answer this question I have this problem too

Is this a good question?

Can you give us the OS-X version you are trying to install.

Sadly you'll need a FireWire HD which has the older OS's this system uses, either OS-9 or OS-X 10.5.8.

Your other option is to boot off of the grey OS installer disks that came with the system or a retail copy of either of the OS's I've listed here.

If your internal drive is dead it likely needs replacing. Have you done that yet?

Sadly, you can't boot up the older PowerPC based systems (G series) under a USB drive, you need to use a FireWire connected drive and the drive needs to have a bootable OS on it for your system.

Depending on the OS version you are working with here you may need an older version or use a boot disk that was created on a G series system as the earlier versions of OS-X had two installs one for PowerPC based systems and the other for Intel based systems.

Google told me, if any, it can only boot via a firewire harddrive, because it is a notebook before intel or sth like that. Just google it
