grey screen, apple logo on startup, spinning progress wheel...

Hi Jess,

So it does boot from the grey repair disc? And you can open Utilities, but your HD does not show up there? If that's all true, it sounds like you need a new HD.

Repair Permissions /Drive from the installer disk

You can then hold c boot off the installer disk for your OS versionand

under the Utilities menu is Disk Utility > Repair Disk and

Repair Permissions.

Any warnings related to Disk Repair that are not repaired

is a sign of trouble.

This one about permissions you can ignore

Select your problem drive and click Repair, yes.

If there are any warnings that are NOT fixed, then state those here. 🙂

Hi Thanks yeah it boots from the disc, but when i click on utilities > disc utility, the 'repair disc' option is there but won't let me click on it...

The HD does show up there and the option to repair it is there - should i click 'repair' under HD? I haven't done this because I thought I was meant to click 'repair' under the disc not the HD??

Thanks heaps...

Select the HD and Repair Disk should be available. Click on it.

The DVD disc is what your Mac booted from because Repair Disk cannot repair a disk if it is booted to that same "volume". So you boot from the DVD, and now it can repair the MBP's HD.

Last night the electricity went out and my power surge protector was not working so my iMac just force shut downed.

So, when the electricity came back i turned on my Mac but it is *Stuck in the Startup/Boot Screen with a Grey Apple Logo,a Empty Progress Bar with stays for 1 or 2 minutes and a small Spinning Wheel which would Spin Forver! I Have tried the SMC and Pram reset but no use, i have also tried to insert my OS X Lion 10.7 Installation disk and it would not load if i hold the C Key in the Startup, I Have Managed to go to Disk Utility Through "Recovery HD" but the Volume "Macintosh HD" is Greyed out and Unmounted and i cannot repair it. There are some files that i'd like to Recover if there is a way to fix it without deleting files.
**PLEASE HELP ME FIX THIS!**

Details about the iMac:

iMac 21.5 Inch i think from Mid 2010,

OS X Lion installed maybe 10.7.2 or 10.7.3 (im not sure)
