New Harddrive Installation: 'Mac OS X cannot be installed'

In Disk Utility under Partition did you make sure the drive was partitioned to use the GUID partition table?

Two things would prevent this:

1.) You don't have the drive partitioned as GUID (as already mentioned).
2.) The discs you are using came with a computer and it's a different model then the one you are trying to install on. Discs that come with the computers are locked to that specific model so you can't install on a different type of machine.

I ran into this same problem and it turns out that I had grabbed an OS install disk that was trying to install a version of MacOS that was older than the one that shipped with the computer.

Even if you have an install disk that's otherwise suitable for doing a full install on any Mac, if it's an older version of the OS than shipped with the computer originally, the install will not work.

That's true also. I forgot to mention that.

Why does it have to be GUID? I'm booting from an MBR partitioned 320 gig in a MBP.

What's a MBR?

Intel Macs require the GUID partitioning to boot. PPCs boot with the previous Apple format.

I doubt this has anything to do with the OP's issue, but Intel Macs can also boot from MBR partitioned drives (Master Boot Record). It is a legacy partitioning scheme from Vista; I neglected to re-do it when I moved the drive to the Mac. After a bit of research, the performance differences are non-existent between the two.

This is my boot drive in a 2.4 Macbook Pro:

Okay....

It's Guid to go!

Got it? Just do it.

I'm surprised that the Leopard installer works on MBR by default. Thanks for the information.

A Simple Solution that requires a bit of hardware.

I've had this problem today with a macbook that was a former employees.

I wiped the drive because I just wanted a clean install. I did this from Disk Utility on the Leopard DVD. Didn't realize I wouldn't be able to reinstall straight from the Leopard DVD and the original install discs appear to be missing.

Here's what I had on hand that made it possible.

1. A Mac OS X install disc (not the one that came with a computer)
2. A LaCie Firewire External drive.
3. A LaCie External DVD drive. Presumable it doesn't matter what manufacturer you're using as long as one of the external drives has dual firewire ports so you can daisy chain them together.

Here's the solution.

1. On another mac (borrow one or find a friend if you don't have one) attach the firewire hard drive and insert a Mac OS X install disc and install OS X on to the external hard drive.
2. Connect the firewire drives together and then to the mac you want OS X installed on.
3. Start up from the external hard drive and put the install disc in the external DVD drive. You should see the OS X DVD mount and then just click it to start the installer. It should restart from the external DVD without trouble.
4. Now it will allow you to install OS X on the internal drive of the macbook or whatever you want it installed on.

It took a minute to figure out, but has saved a ton of trouble. Most of the solutions I've seen for this require getting into command line and disc images and I'm not interested in messing around with that.

Hope that helps people.

That is a good suggestion, but I don't have an external DVD.

My solution: I joined one mac to another using a firewire cable, started the (newer) destination Macbook in target mode (apple-t on startup), and proceeded to use the old installation discs belonging to the older Macbook to install the older Mac OS on the newer Macbook's internal hard drive.

Mac OS X cannot be installed

I have a PPC G5 and just put two new 250 GB SATA 300 drives in it. They are formatted Mac OS X Extended (journaled) and using the Apple Partition format. I should not have to make them GUID yet I still can't get the install going. Please advise

Are you trying to install with a disc for a specific model of computer, which would be indicated by the disc being grey? If so, you'll need the retail disc which is black.

EDIT - oops, I should learn to check post dates.

That's it

chrfr-that's it! awesome-thanks!

I partitioned as GUID, didn't work.

Got the correct Leopard disc, worked.

Thanks guys!

My original hard drive crashed a few months ago. I started in safe mode to get to Disk Utility and it wasn't there so I knew it was fried. My MB (white mid 2007) originally came with Tiger, but I only have a Snow Leopard Install DVD. I assumed that would work because all of Apple's documentation says you shouldn't install an earlier version, but nothing about a later version.

So I got a new hard drive, same brand and everything. At power up, I held down Option/Alt and I could select the install DVD as my start up. I could then get to Disk Utility and was able to partition the new HD. For some reason, the DVD looks like it wants to install, but it gives me a pop up that says it can't install and asks me to back up from Time Machine or another back up. So I tried to follow some other posts and tried to repair the disk and permissions, but it didn't need permissions fixed. I checked the Startup Disk Utility and my HD didn't show up there. It only had the Install DVD and a Network drive (which I don't have). It says it is a MacBook Mac OS X Install DVD. Mac OS version 10.6.3, Disc version 1.0, 2Z691-6653-A.

If you have a Snow Leopard disc, you need the retail one, which is white. Call the Apple store, I believe they will still sell you one for $29.
