SOLVED: Need help reformatting iMac G5

post #1 of 8
Thread Starter 
Alright well i just purchased a iMac G5 17" from my friend who had no idea what he was doing and well nether do i...

Its running xubuntu and i'm trying to get it back to factory setting so i can learn how to run macs (as this is my very first time on one)

Thing is whenever i put in my Mac os 9 install disk and restart i hold "c" to boot from CDROM it just flickers the screen and loads normally.

now ive also made a bootable USB drive with ubuntu version 11.04 or whatever it is, restarted the mac and held alt to boot into the usb and it only displays the hard drive which already has linux on it.

im also running a windows (G15 keyboard) as i don't have a mac keyboard/mouse.

Anyone got any idea's as to what im doing wrong as im sure im screwing something up here...

You need an OS 10 (aka OS X) disc. Obtain one from the source of your choice, then boot to it with the C key.

I don't understand the question here. Are you trying to restore the mac to the apple OS, or just trying to put a clean OS on the system?

If it's the latter, depending on how old the mac is, it might not support booting from USB. You'll probably have to deal with burning a CD and booting from that. I admit to having no experience with macs, but if it has anything resembling a BIOS where you can select boot device order, I'd suggest you start with either putting the CDrom drive in the first slot, or disabling your HDD from the boot list altogether and go from there.

Yah im trying to get it back to mac os i don't want to run linux on it no more.

i tried to run the os x disk but holding C seems to be doing nothing as it still boots right back into ubuntu...

A G5 machine will not boot from a USB drive, it would have to be through firewire or a physical disc in the machine. Suggest burning a DVD would probably be the easiest way forward for you unless you have a spare firewire drive around.

It's also worth pointing out that holding down 'C' wouldn't load an external HD. You are better off holding down 'Alt' or option key (depending on where your keyboard is from) to get the boot manager up and selecting it from there.

You're not sure?

Even though you can use a non-Mac keyboard okay, I would strongly recommend get a proper Mac keyboard for the G5. You will find it much easier to use, especially for the Option keys etc.
