iMac 17" 1.9GHz Hard Drive/OS Install Problem

Hi all,

I have an iMac 17" 1.9GHz (PPC) 1.5GB RAM that had Mac OSX 10.5 installed on the original 160GB WD SATA drive. That drive failed and was replaced with a 500GB Seagate SATA drive.

I have tried installing OSX 10.3 & 10.4 on the new drive, but the slot-loading superdrive is not reading well. So I connected the iMac to a Macbook Pro (Intel) running OSX 10.5.8 via Firewire to install OSX 10.4 onto the iMac.

The Macbook Pro saw the firewire HD and asked to initialize it. I then created a new partition using the Apple Partition Map (Mac OS Extended (journaled)). The Macbook Pro also reads the superdrive in the iMac most of the time (every so often the drive ejects a perfectly good disc and then takes it the next time the same disc is inserted). I tried installing OSX 10.4 DVD onto the iMac's new internal HD using the DVD in the iMac superdrive AND in the Macbook Pro's drive and both times the installation was a "success" (according to the installation application running on the Macbook Pro). However upon rebooting the iMac I am greeted with the blinking ?/mac folder icon.

I then connected an older LaCie Firewire CDRW and, using a separate set of OSX 10.4 CDs, I tried to launch the installation program on the iMac. I tried both pressing "C" and holding down the option key at boot. When pressing "C", it took until just after the blinking ?/Folder icon appeared and then it detected and ran the firewire CDRW resulting in the CD booting up, the apple logo appears for a few seconds and then changes into the "prohibitory sign" / "no entry" or circle with a slash through it. It goes no further. When pressing the option key, it gives me the option of going forward with my only choice-"the Mac OS X Installation Disc", but I still end up getting the "prohibitory sign" logo after the apple logo.

Oh, two other notable things: First, when I have installed it thru the Macbook, I can access all the files on the target internal HD in the iMac (though I did notice a conspicuous lack of the BootX (it is a PPC iMac) in the System\Library\CoreServices folder after a successful "installation". Second, when I entered the Open Firmware on the iMac, I was able to use the command- dir hd:\ and see the folders & files on the internal hd, and the boot-device environmental variable was set to hd:,\\tbxi (the default)...still end up getting the blinking ?/Folder icon.

I'm stumped. Any ideas? Thanks in advance!
 
Your iMac G5 iSight originally shipped with 10.4.2 or higher - so may not boot from a 10.4 installer. Do you actually have a 10.4 install, or is it a higher version, such as 10.4.6? It will show the version on the disk label. If it really is 10.4, then you need to find a higher version installer.
If you previously had 10.5 installed on your iMac, why not just use the Leopard installer, and be done with it?
 
Ahhhh....10.4.2. Ok I will try your suggestion and post the results (will also resume my search for my 10.5 discs as well). Thank you for the quick reply!!!!
 
Thank you, DeltaMac!

As it turns out, the 10.5 did install, but as with 10.4 and 10.3, I still got the same blinking ? icon at boot! Discouraged, I found a site explaining how to install Mac OSX onto a flash drive...that is where I found an additional step of blessing the new system after installation! I hadn't done this and figured, what the heck...So I reconnected via firewire to my Macbook Pro, entered the terminal and used the following command:

"sudo bless -verbose -folder "/Volumes/MacHD/System/Library/CoreServices" -bootinfo"

where "MacHD" is the name of the partition. I then disconnected and was immediately able to boot normally with the iMac! Thank you for the 10.5 suggestion and for anyone else with a similar problem, the bless command was necessary for me!!!
 
I should have added this to my earlier post...this is exactly as taken from the terminal and I wanted to make sure I showed my "work" as it were :) :
