installmacos
since I was not longer using the Server options on my mac mini I wanted to install os x mountain lion, so I downloaded the app and selected the appropriate hard disk. now, after it booted i'm stuck on the grey fabric background.
there's no signal of life and nothing printed on the screen.
I have several macs around here at the office, how can I try to finish the installation at this point?
the mac mini is the 2007/08 version i think
thanks!
This shouldn't be a concern. (I followed the same path of installing the GM seed.) The App Store allows you to re-download the installer if you desire, but indeed, the build you installed is the same as the release version. If > About This Mac shows Mountain Lion, you're running Mountain Lion!
You can download apps you've purchased before (including OS X installers) from the Mac App Store application. Sign in and switch to the purchases tab:
All of your previous purchases should appear, including the Lion installer:
If you don't have the App Store, make sure you've updated to at least 10.6.6.

According to this support article, the system requirements call for a Mac Mini from 2009 or newer. The model number A1283 corresponds to each of the three Mac Minis that were manufactured in 2009 (Early 2009, Late 2009, and Server), so your hardware is compatible. The install image has disappeared because you began the installation process; this is supposed to happen, as the image was not designed to be persistent. The reason that the image is not persistent is partly because (if the installation is successful) if your file system were to become corrupted, for example, you would be able to boot from a separate partition that is made at the time of installation, called the Recovery Partition. In your case this did not happen, so you have neither the recovery partition nor the install media.
To fix your problem you will need to use another Mac, at least to begin with. The first step comes in two, simultaneous parts:
This will take a while, so be patient.
The next step is to upgrade your Mini to at least Snow Leopard (10.6.6). Although this really is a requirement only so you have the Mac App store on the machine. This was a requirement to download 10.8, which is available only through the Mac App store. Since you're downloading 10.8 from a different machine, I guess it would be possible to go from 10.6.x to 10.8, but I've never heard of anyone doing it. Probably just the safest to go ahead and get things updated to 10.6.6 or higher.
Once your Mac Mini has been restored and updated, go ahead and run "Verify Disk" through Disk Utility, just to be sure that the file structure is squeaky clean. It can't hurt, even though you've gone straight from a clean installation through some upgrades without anything in between, so go ahead and run it to make sure everything is spec.
Once that's all been done, go ahead and use your flash drive installer to attempt another installation of Mountain Lion. Not all installs work perfectly the first time through, so it may be that this one goes perfectly smoothly for you.
Good luck!
