    Well, this might be anachronistic to ask about 10.5 when talks of Lion are in air
    but I am stuck with problem

    I tried to install 10.6 on my mac-book which was having 10.5.8 installed on it.
    Two successive attempts failed and I decided to reinstall 10.5.

    But I got following error
    Mac OS X cannot be installed on this computer.
    This software cannot be install on this computer ​

    I have tried erasing the drive , repartitioning with "Disk utility" of 10.5 installation DVD as well as 10.6 DVD .
    but error remains unaffected

    Currently my Macbook is without any OS

    Help awaited , Thanks

    Have you checked that your Macbook is compatible with Snow Leopard? Dumb question, but that's the only real thing I can think of if you've already tried wiping the drive and repartitioning. Are you repartitioning with "1 Partition" (vs. "Current"), in "Mac OS Extended (Journaled)" Format, and "Options..." as "GUID Partition Table"?

    Yes, my macbook is compatible with Snow Leopard


    Earlier I had partitioning options set to default but now I have tried the options suggested by you unfortunately problem persists :mad:

    Sounds as if you are using a grey Apple 10.5 disk ?

    It may be the wrong disk for that MacBook...

    Which model of MacBook - specs - is it ?

    What does the 10.5 disc say on it ?

    Is my mac-book compatible with Mac OS X Lion?
    Wikipedia says it is compatible with x86-64 processor (Macs with an Intel Core 2 Duo or later CPU)

    my friend offered me his DP copy of Lion

    The gray disk should be ok then but it will be 10.5.2 or 10.5.4.....

    Sounds more like a HD problem in that case ...

    Have you tried the Apple Hardware Test on the installation DVD?

    It's usually on DVD 1, press D at startup to run it.

    If it says 10.5 then it is the wrong disk for your MacBook - that disk is for the earlier 3,1 MacBook models and you cannot use it to install OSX.

    Have you tried booting from the dvd and running the hardware test (hold down d while starting up) - because that should not work either.

    The install disc will allow you to run disk utility but not install the OS.

    I could run the hardware test but I am getting following error there

    "Apple Hardware Test does not support this machine"


    I guess, 10.6 OS disk has upgraded the firmware causing it incompatible with 10.5 Installation disk ....

    Additions information which might help

    SMC Version : 1.31f1
    Boot ROM version : MB41.00C1.B00

    I'm not aware of Apple installing firmware updates with the OS Installation. They are usually notified via Software Update, or downloaded manually from support.apple.com.

    Latest versions and download links are listed here : http://support.apple.com/kb/HT1237

    I've got a sneaking suspicion you've got incorrect OS disks if it gives that error on the AHT. The 10.5 discs that shipped with the machine will be locked to stop them being used on a different type of Mac.

    That error means you're trying to install from a machine-specific OS install disk that isn't your machine. A retail Snow Leopard disk should not give you that message.

    Correct - the disks you have are not for that MacBook...

    Is the 10.6 disk a retail copy or a grey disk from a MacBook or what ???

    As per discussed here , I decided to give a try with installation DVD having version 10.5.4 and I have successfully installed my macbook with 10.5.4 OS.

    All the installations DVD which I have , are came bounded with hardware purchase i.e they are grey DVDs


    Sent from my macbook with 10.5.4 :apple:

    To install 10.6 you will need a full retail copy, ie not a grey disc. Your MacBook never shipped with 10.6 pre-installed.

    me too... learnt from the hard way.

    how i did it was, put my harddisk to a SL capable installed machine say MB7,1. fresh install from its SL disc. then took the disc out and put it back to my machine, and it worked... fiddle but maybe it would work for you too.
