Hi there I have a fairly new iMac running on Mountain Lion and it is stuck on the grey screen with the apple symbol and a spinning disk.
Several times it has restarted with a bar at the bottom that gradually turns dark grey but then switches off again on completion.
Can anybody offer any advice.
Thanks
Neil
iMac, OS X Mountain Lion (10.8.1)
Boot into the recovery partition by holding the command and r keys down during the boot. Use Disk Utility to repair the hard drive. Assuming no unfixed errors, boot normally and hopefully all goes well!

Hi I did what BGreg recommended and used the first aid part of Mac OS X Base System.
It said the Mac OS X Base System appears to be ok
Not quite sure what I should do now as there is no restart option
Forget that it would appear i was doing the wrong one I verified 1TB WDC100FALS and that was ok, so then went onto
Macintosh HD - NOT GOOD
Disk cannot be repaired
I backup to an Iomega 2TB what should i do?
When Disk Utility can't repair a disk, as long as there isn't a hardware failure, programs like Disk Warrior and TechTool Pro can usually fix them. Disk Warrior is the preferred product. Did you get a tree error or something indicating a data issue?
Another test would be to run the Apple hardware test to see if there are any hardware issues associated with the disk.
If you don't want to use Disk Warrior to repair the drive, you could erase it by writing zero's to it with Disk Utility, then restore your data from your backup. But do the hardware test first. If the drive has issues, then this may only be a temporary solution.
It says
Error: Disk Utility can't repair this disk.... disk, and restore your backed-up files.
what the **** does that mean
Thanks BGreg that sounds great but dont really know what you mean.
I know where the power button is located and that is about the extent of my knowledge
Was there any sort of informational message in front of that? Usually, but not always, it gives you a one liner on what the issue is.
Incorrect number of thread records
Invalid volume directory counts
Invalid volume file count
Incorrect number of extended attributes
You have directory damage. You should not use your computer until the damage has been repaired to avoid further damaging your directory.
The following software will repair your directory:
You must use the versions that are compatible w/your OS system & keep the utilities updated to avoid damaging/harming/trashing your system.
DiskWarrior Highly recommended for *directory damage* repairs.
TechTool Pro Multi-functional utility.
Drive Genius Multi-functional utility.
You will need to make your own decision on which to purchase. Read up on them on their websites because each does something a little different.
These are 'soft' errors that can be fixed by Disk Warrior. You can buy it by following the link above. You shouldn't have to erase your hard drive or restore from your backup. In most cases, Disk Warrior will be all you need.
I guess i will need the DVD version or can i do it via my macbook or iomega external hard drive?
While you should confirm with Disk Warrior, I think you'll need the DVD version so you can boot to it. If your iMac could boot on it's own, then you could either download it or access the hard drive through a wired connection to another mac system, however, that's not the case here.
