Cannot install any version of OS X

[optimistique1]

Hi all, this is my first post and I am in desperate need of some help please.

I have a Powermac G4 Cube - 450Mhz - 1.25GB RAM - 80GB HDD. I recently bought this item used with OS X already installed. I then did an erase and install with os x 10.4 to get a clean system and then proceeded to update to 10.4.11 with the combi update. Unfortunately half way through the update I had a power cut and upon reboot I got the prompt to shut down which I did.

I then tried to restart the it would just get to the grey apple screen and nothing happens. I then did another erase and install of 10.4.0 and upon reboot the same happened again, I get to the grey screen with the whirling wheel, the wheel stops whirling and nothing happens.

So I reboot holding down C, go to disk utility, repair permissions (nothing needed to repair) and repair disk, again nothing needed repairing.

I then reboot into safe mode and do the same go to disk utility, repair permissions (nothing needed to repair) and repair disk, again nothing needed repairing.

I then realise the firmware is not up to date so install os 9.2.2, install firmware successfully, then erase and reinstall os x 10.4.0. Upon reboot the same happened again, I get to the grey screen with the whirling wheel, the wheel stops whirling and nothing happens.

I recently installed Airport and also new RAM so I took the new RAM out to see if that made any difference I still only get to the grey screen with the whirling wheel, the wheel stops whirling and nothing happens.

I also reset the PRAM.

I am completely at my wits end and really do not know what to do now. It seems that the machine will only install os9, so how did the previous owner install os x? In fact, how did I manage to install os x before my power cut but can no longer install it?

Can anyone offer me any help before this mac flies out of the window....

Many thanks

Garry

Did you use the DIsk Utlity on the install disc to delete all the partitions on the disk and then repartion with a single HFS+ partition?

Hi,

Do you have an external drive you could test boot from?

I second this one. Completely repartition the drive. It sounds like a wonky bootloader that a reinstall isn't refreshing.

Hi All, I ran the Apple Hardware Test last night and it came up with the error with the Airport Card, could this possibly be the cause? I did not have time to take it out and try again as I had to get back to work?
