I have installed a new hard drive as the old one was corrupted but the tyre tracks have been showing up on the screen for sometime and this is what I got if I tried to boot up on a disk.
The new drive is a Western Digital green 1TB - old one was Seagate Barracuda 7200. Used ifixit - went well and reseated ram afterwards. Put old drive in caddy - if I try and boot up on that, get the same as when it was in Mac ie Apple, spinning wheel, bar starts 1cm in turns Mac off.
If I try and boot up on Lion recovery flash which I made ages ago or OSX disks or Disk Warrior (bought too late to save old drive) Apple, spinning wheel, after 3 mins blue screen for 30 secs then as in picture. Basically, it is doing the same now as it was before I changed the drive - could there be another problem? Disk is not formatted so am trying to boot up on OSX to start formatting. Have tried original OSX (Tiger) and Snow Leopard.
