Hi, I am looking to sell my iMac 2007 so I tried wiping everything off it,, I put the mac os x disk in to wipe it through that. So I used disk utility to wipe my hard drive. Then I restarted my computer but it comes up with a flashing folder with a question mark, so I put the mac os x disk back in and It says "this software cannot be installed on this computer, please help, thanks.

It sounds like you don't have a valid OS disk for the machine.

You have to either have a retail copy (generally Black) or if one of the Gray OS disks it has to be the same model as these are machine specific.

I have checked that I have got the right disk and I think it is, it is version 10.5.2 and the apple website says that's the right one for iMac 2007, and it is a grey cD

Did this gray/silver Mac OS disk come with this computer originally (when new)? If not...then it won't work...the gray disks are model specific.

It means nothing that you purchased this computer from a "top rated seller on e-Bay"...in fact (since you didn't buy this computer brand new)...this makes it even more possible that the gray disks you have are NOT for your computer.

If you inserted the gray disk into your computer...held down the "C" key to get the computer to boot from the disk...and the computer says that it can't boot from this CD/DVD...then it's the wrong disk for this computer...or the disk is damaged in some way.

Your best bet...and least expense...is to purchase a retail Mac OS 10.6 install DVD:

Mac OS X 10.6 Snow Leopard - Apple Store (U.S.)

By the way...I just checked...and 2007 iMac's DID NOT ship with OS 10.5.2...they shipped with an OS version between 10.4.7 - 10.4.10 (depending on the model).

This verify's that the gray 10.5.2 disk you have is NOT for your computer.

- Nick

p.s. This assumes that you are correctly identifying your computer as a "2007 iMac". OS 10.5.2 did ship with early 2008 model iMacs.

Nope. OS 10.4.10 may have been the OS version that originally shipped with your computer...but haven't you ever heard of folks upgrading their OS to a newer version??;)

If your iMac has a core 2 duo processor (which I think it does)...it can run the latest Mac OS version...10.7.2 "Lion".

So you can run any OS version from 10.4.10 and beyond (10.5.x, 10.6.x, 10.7.x)...your choice.:)

But where can I buy a 10.4.7 disk?

Why would you want to purchase an OS 10.4.7 disk...when you just said that the Apple website says that it needs OS 10.4.10???

Getting an older OS version (10.4.7) than your Mac requires (10.4.10) won't work!!!

You haven't told us the exact model iMac you have...so there's no point in going futher until we know.

If you have the retail (white disk) Snow Leopard you should be able to install that with no problems.
If not, Snow Leopard is still available direct from Apple for $29.

Since your Mac boots from the CD run Disk Utility once it's booted.

Select the drive and run verify then repair if indicated.

I have seen the error you mentioned at the beginning of the thread when there was a problem with the partition.

If you don't have anything of value on it then you might consider deleting it and creating a new one.

I have just tried both these things and it still says that it cannot be installed on this computer,, I think my best bet is to buy a copy of a mac os x 10.4.8 as that is what my iMac was suppose to come with,, anyone agree? Thanks again guys
