First, what's the problem you're having with the 10.6 installer? Is it the grey installer that has iMac written on it, or is it a retail copy (big X on the front)?
You could TRY cloning your MBP to the iMac, so long as the iMac drive is larger than your used filespace on the MBP. Connect the two with a Firewire cable, reboot the iMac with the T key held down, and you'll see the Firewire symbol on the iMac, and its drive will mount to the MBP desktop. You can now run Carbon Copy Cloner or SuperDuper to clone the MBP to the iMac.
Thanks Matt for the fast reply..
I have a white install DVD .. It say Mac OS X Snow Leopard across the top.
I have tryed to install it but it comes up with,, software unable to install from disk.
Cloning from my Macbook pro would be the way to go if it possiable.
Not sure what you mean by size of filespace.. Is this the whole drive or just the amount that is used up????
Macbook pro has a 500 GB hard drive and the Imac has a 320 GB hard drive.
Thanks for the Help...
The only way to reinstall Snow Leopard, which you Must Do, is to First Wipe the drive by booting the system from the Snow Leopard install disc and use Disk Utility to Re-Partition the Dirve As ONE Partition. That is the only way to get rid of the Lion installed Recovery HD partition on the hard drive. Otherwise the SL installer see that and will not continue.
Again you MUST BOOT the system from the SL install DVD disc.
To do that put the SL DVd in the DVD drive and reboot the system. At the Chime hold down the Option key and from the screenn that comes up select the DVD drive, SL DVD disc, as the Boot Source.
Also you Really NEED the Original system disks for that system. Without them you can not install the originally included iLife Apps without buying them from the Mac App Store and even then you don't get all of them. Apple has dropped 2 of them.
To get a set of Original Install discs you need to contact Apple and order a replacement set for a small fee.
Ok Thanks guys..
Getting my head around this now..
So i have the Standard SL upgrade DVD which is not the right DVD for what i'm trying to do..
I will contact apple and order a replacement Original system disk.
I did get the ilife 09 disk with the imac which i have installed.
Going back to my clone question, I need to buy a firewire cable so i can conect the macbook pro to the i mac after i have reinstalled Snow leopard. Is this right ???
No Not Really. That DVD should work for reinstalling Snow Leopard on that model year system but you need to RE-PARTITION the drive as ONE partition. There is a Hidden partition on the drive that contains the Lion Recovery HD. You MUST get rid of that partition for SL to Reinstall.
Ok you got "A" iLife 09 disc. Then if you are successful in reinstalling SL,, after you Re-Partition the drive, then that 09 iLife disc should work to reinstall all of the iLife Apps
That iMac came with OS X 10.5.2. So I don't know what is worth getting the original DVD, considering that you also have the iLife '09 disk.
You can completely wipe the internal iMac disk starting from SL DVD, launching Terminal and issue this command
that should return /dev/disk0 as your internal iMac disk, and
diskutil eraseDisk JHFS+ MacOS_SYS disk0 GPT
to wipe and format the entire disk with one GPT, HFS+ journaled formatted volume, named MacOS_SYS.
Sure I've done that myself. Had Mt Lion installed, along with both Snow Leopard and Lion on one disk, 3 partitions, along with 2 recovery HD partitions, one for Lion and one for Mt Lion. Decided to go back to Lion only and Re-Partitioned the drive As One partition from the Lion Online Internet recovery system, which Lion came Pre-Installed on my Mac, and All Partitions where deleted, They Have to Be otherwise it wouldn't be One Partition on the disk.
Even though the Recovery HD is hidden from "User" "View" it is Not hidden fron the base Disk Utility system. It can even be displayed after you enable the Debug menu option in DU.
I would not of posted what I did without being Completely sure it was correct. That is if I don't add a Disclaimer like I think or More then likely. Which I did not.
