problem with upgrading mac

I have just tried to upgrade my imac G5 with a leopard upgrade, while installing a message was coming up saying the the disk is damaged or needs cleaning but after cleaning the disk more than once it was still doing the same think,so i quite the install. Now when i try a boot up my mac there is nothing there and i can''t see my original os x?

that sounds about right
the old operating system has been trashed by the aborted upgrade. The attempts at "cleaning" the drive may well have effectively reformatted it
You need a new hard drive

sorry i ment the dvd with os x upgrade needed cleaning not the hard disk,and it was only a upgrade i was doing not a fuul install so i would of thought the info data would still be there!!

in that case different diagnosis: - no you don't need a new hard drive
However, from my (limited) experience of Macs, I'd still say the abortive upgrade has trashed the operating system
In windows you could try a "repair installation" - but I don't know if a Mac has that capability. Otherwise you're probably looking at a reformat and clean intallation

Hi Courtney,

you will need to get a replacement set of discs or post a job on the PCIQ system, asking for a tech who can reinstall your operating system from their installation media. Also let them know if you need them to recover your documents, because your machine will need a clean install.

In the unlikely event your local PCIQ people are all on holiday, let us know on this thread.

do I take it from that, that you have to do a clean install, then followed by the upgrade?

If you can get a good copy of teh Leopard CD, you should be able to boot from that. Then hopefully you will be able to see exactly what is on teh hard disk, and if your data is there, copy it off ( onto another disk, USB stick or CD/DVD.).

To boot a Mac from CD, press the "C" key during startup.

Thanks for the help,i will try this weekend and let you know
