Hi Cait If you have the recovery tool on a USB thumb drive, just insert the drive, and when you boot the system hold down the option key. Give it 10/20 seconds, then hit the left/right cursor key once and press Enter. This should cause your machine to boot from the thumb drive and give you the options. I strongly suggest that, in the first table of options, you select Disk Utility and then re-partition your hard drive. Be sure to select "Mac OS X (Journaled)" from the list of options. Then in the "Options" section, select "GUID" partition type, click Apply, then click Partition.
Once done, then you can proceed to the install as normal. This is a problem which I've only seen once in over 7 years of Mac usage. I honestly can't remember whether this indicates a hardware problem or a software one. I thick it was software, and I hope it was.

I'm running mountain lion now, how would I go about reinstalling it from scratch, please? Mark made us a usb stick with ml on it and I am now putting all my important stuff on my back up drives so I can do everything cleanly. thanks, Cait On 2012-09-04, at 2:05 PM, Gordon Smith <[email protected]> wrote: > Hi Cait > > This sounds like a pretty nasty systemic permissions issue.
