Morning folks. I'm in a bit of a pickle with this one - my PowerMac G4 MDD was mid-update (updating to 10.5.6) and as it was late and I was in something of a rush I took the usual step of forcing it to shut down, ie., held the power button for a good few seconds. This was in the hope that OS X would some how pick-up where it left off on the next boot and continue its merry way performing the update. I was wrong! Very wrong!! All it did was sit there with the "spinny thing" on the Apple logo screen and then it proceeded to eventually continue to switch between a dark blue screen and a light blue screen - I left it for a good 15 minutes or so in the hope that it was trying to repair itself. I then reset the PRAM, still nothing! In-fact this time around it did the "spinny thing" for a minute or so and then switched itself off! Further more, the machine won't boot from OS X CD either! So by now I'm thinking it's a corrupt drive... So I swapped my boot drive with my empty data drive in an attempt to try and install a clean copy of the OS with the PowerMac G4 hooked up to my MacBook in target mode, as in I performed the install from my MacBook onto my PM G4. The install went fine (once I'd repartitioned the drive as GUID making it bootable) - so then I went to reboot and.... I got a flashing folder with a question mark!! I'm now totally lost as to what the heck to do!! There's a SCSI card and a USB 2.0 card in there at the moment - could either of these be causing an issue with regards to the booting? Any help would seriously be appreciated right now!! Many thanks and kind regards, Mark.
