Mavericks fail on iMac 7.1

[Lambertus]

Hi there,

I have been trying to install Mavericks on my 24" imac 7.1.
It just Will not start up after install. Tried from AppStore in 10.6.8 and clean install. Can only go to 'restore Osx 10.9.1' after starting up with option pressed.

Specs: 2.4", 2,8 GHz, 4gb, 1tb.

Who can help me out?

Can you boot into Recovery Mode and use Disk Utility on your drive?

In the meantime I've fiddling a lot.
First I fully restored my previous situation from my time machine.

After several attempts with 10.9 (from bootable HD or DVD) I tried installing retail 10.8 and it fails as well(?). But now it comes back with notices that the partition I want to install on is defect and cannot accept OSX. If, in that situation I run the disk utility, it confirms that this partition needs re-formatting etc. When I then do that, it comes back within 10 secs and reports that the disk cannot be repaired.....!
I then boot with the 10.6 installer disk and am able to restore my time machine backup on the very same partition with no hickup or message. Running disk recovery then reports only green lines.... This is puzzling.

What is wrong? What do I do wrong. I'm no expert but with 27 years of mac experience, I haven't stumbled over this ever.

Your hard drive is 6 years old at least and might be dying.

Tnx for the reply. The 500gb originals have a bad reputation->

Allready did that. Replaced it 2 yrs back with a WD 1tb (WDC WD10EZRX).

Run Apple Hardware Test and report back if any issues crop up.

Otherwise, it's possible the download of both ML and Mavericks became corrupted somehow. Can't think of any other plausible explanations.

if your harddisk has problems

try to install a new system of 10.9 on an external USB, or better FW800 harddisk!
