Big problems with OS X Mountain lion install

[dalby]

Hello

I bought a used Imac (just over a year old). It is born with Lion which was on the machine when I got it.

When I tried to install the machine again I started to erase the hard drive and insert my USB key with Mountain lion that I have used on my other Macs, to create a "Clean install".

The problem comes at the error message I repeatedly get after a few minutes of installation. Note the computer is connected to the Internet, and I have tried both wired and wireless on several different networks.

Error message: "Can not download the additional components needed to install Mac OS X"

I have also tried to install Lion with the USB key and get the same error message.

Next, I tried to make "internet recovery" by pressing "cmd + alt + R". The installation starts.

However, I get the exact same error message again, after the computer has been running the installation a few hours!

PT, I have an Imac which can not be used for anything.

Apple Support had no other advice than to try on a different network, as they believed the error was due to the network!

I currently have tried 3 different wireless network and 2 wired and spent between 10 and 15 hours on the project.

Has run out of good ideas!

Experience or advice very welcome! ...........

Regards Kristian

If you live close enough to an Apple Store, make an appointment with the Genius Bar. When you are at the store, explain that you are having problems reinstalling OS X and you would like to go through the process with them.

It would give you another network to try and if there is an issue, they can't say it's a bad WiFi network.

I'm kinda confused here. If you have a ML USB installer you don't even need Internet access and there should be nothing downloading at all.

Just option key boot to the USB key then use Disk Util to erase the drive then click install. You can do this in the middle of the Atlantic without Internet access.
