Cannot install Mac OS X disk failed with error could not unmount disk
Posted on 2007-08-01
Hi Macintosh gurus,
I am in a bit of problem at the moment, I have a Intel MacBook it had 10.4.10 installed on it I could not load Mac: Office on to the machine so I was advised to reinstall Mac OS X 10.4.11 on the machine and then try. I must admit in my hast I powered down the machine a couple of times using the power button and started the MacBook from the DVD, I got with the laptop. All went well till now, but after the install reaches half way it says cannot install please try again.
I am thinking well let me format the disk from the Disk utility, which I did and restarted the machine then it did the same thing and stopped halfway with the error. When I tried to verify and repair the disk using Disk Utility I keep get the error disk failed with error could not unmount disk what ever the hell that means, this error does not appear when I restart and then verify or repair disk.
I need to install OS X on this laptop what should I do? Please help
I have tried to Zero the hard drive and install the OS Again.
