OK, i have a macbook pro 15" and a 17"..

The 17" has Snow Leopard installed but i need to do a reinstall on it, the trouble is i cant find my SL disc! so, i tried to load the disc that came with the 15" but i keep getting the message

"Mac OS x cannot be installed on this computer"

is this because the version of OSX is lower than what is on the machine??

Thanks in advance guys...
 
Yep, sounds like it. If you're not too fussed about the data on there load of Disk Utility during the setup for OSX Leopard and blow the partition with Snow Leopard away. The installer should then complete as normal on a fresh install.

Spot on, or back the data up then blow the partition and install.

If you have a valid SL disc (but lost it) Apple are usually quite nice about that and will send out another one, at least that is what happened with me although my SL disc was slightly scratched and would not install rather than lost, so they sent me out another.
 
Thanks for the responses so far guys.. my computing skills are quite limited! when i start trying to reinstall i get to the part where it says to choose a language, and then i get the message.. i dont see a way to blow any partition! or load Disk Utilities!

Sorry for being dumb.. :nuts:

Thats great news! i was going to go and buy one! i work around the corner from an Apple shop.. ill pop in later today.. :)
 
Thanks for that, im about to try it! god help me! lol..
 
What do you do once in the Disc Utility?
 
Format, partition disk

Format it as journalised.

once completed quit disk utilities and then carry on doing install
 
Thanks for that Robin, i figured it would be something like that but didnt want to jump in and **** it up! :D
 
Thats fine, i done have too much on it that isnt on my main machine..
 
Do you use Time Machine for your backups out of interest? If not it's very handy for system restores, more so using a f/w or USB drive than a network drive as that can get very slooooooooooooooow.
 
I use carbon copy cloner (free app) which I run weekly. (to a 250GB drive)

Also I do time machine to my new 1TB drive.

Always always back up.
 
Just one caveat that nobody here seems to have mentioned. I'm pretty sure you have to make sure that the version of Mac OSX that was installed on your machine when you bought it is the same or lower than the disc you are using to install it with. Not just what's installed on it right now. If it came with snow leopard and you are trying to install leopard on it then it won't work, you won't be able to boot from the dvd at all because your machine has updated drivers that arent on the old disc.

If this is the case you will probably need to wipe it as some have said and then plug it into your other mac and run it in target disc mode then install leopard from your other mac onto the one that was wiped. I actually don't even know if that would work
 
That why you have to wipe the hard drive first or it will not work.

Once installed you will have to run the updates.

For ease I download the updates as they come up and keep them on my hard drive (backed up) so I can quickly run updates again without having to download them again.

But if the older version of OSX doesn't contain the drivers for the hardware connected to the particular macbook then it won't matter if the hard drive is wiped surely?

I'm talking about things like the keyboard and the cd drive, the bluetooth and the mouse trackpad. All these still need drivers installed and if these had changed between osx versions it's not going to work is it?
