Back up all data.
Boot from your recovery partition by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
When the Recovery desktop appears, reinstall the Mac OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

I've down that and held down command-R on the boot up.
I released the keys as soon as the spining dial appeared. It carried on for about 20 seconds, then a 'no entry' sign has appeared and the spinning dial has continued. I've never ever seen the 'no entry' (a circle with single line running across it) before.

On the 5th attempt it has got through and offered me the chance to reload Lion.
However, when I reach the disk choice of installing OSX Lion the disk 'recovery HD' appears greyed out and states 'This disk is locked'.

On second thought, no, don't try to reinstall on that drive. It's malfunctioning, or you have some other hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go, if you still can.

Most docs are backed up.
However, itunes hasn't been backed up for 2 weeks and I just ripped a load of music from old CD's so that is a pain.
But the main problem is iPhoto. I've had an Easter Holiday and downloaded and edited lots of pics in the past fortnight. I haven't backed up iPhoto for about a month. I do have 'iCloud', whether that has taken all those shots in the 'cloud' is another matter..?

There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

I'm going to set about doing this now which is 11pm UK time, will post back to you sometime in the next 12 hours. Many thanks indeed for your help. Hope I manage to salvage ALL the material

Because my Macbook Pro and iMac don't have the right Firewire connections I had to get my old iMac out and did a firewire 800-400 connection.
Unfortunately now my newer iMac doesn't recognise any keyboard commands so that route is now gone.
I have a genius appointment at my nearest Applestore this morning and will update you later.

Genius bar were superb. The hard disk has had it but not to the extent that we couldn't get 60gig of music and 8 gig of pics off so delighted. They copied all the folders onto my laptop via firewire. Very pleased.
iMac is left with them for a new hard drive which they hope will be able to get back in its original state before it crashed. Not a problem if they can't as I now have everything off the old drive. Must learn to back up every week rather than every month.
Thanks for your help.

To whomever can help...I'm having the same problem as stated above however my HD keeps showing up (it didn't at firs) so I went and took ma a bazillion times but i re-partioned my mac drive to 2 partitions... 1 @ 300gb for Mac HD and one for 200 fro windows 7 I'm putting on it. I installed more ram (came with 4gb ram, updated with 8 more ddr 3 to = 12gb total). When I plugged the Imac back in it had a small spark at the cord. I then turned on the imac...with just a white screen coming up...multiple times. I then figured out how to get it up and partioned as stated above through disk utility and re-installed lion onto the Mac HD (journalized btw) and the Windows 7 partion i did in exFAT mode as iI saw on another forum to do. I am now waiting on Lion to reinstall for a 2nd time as the first time it complleted the install then went to the white screen and I had to reboot it again. I'm not quite sure what I'm supposed to do to get the update that you guys are saying to use the Taerminal as i'm savvy at DOS prompt but not Terminal. I really hope the HD isn't fried as I just replaced my laptop's hd with a SSD (intel 128gb). I have a few backups from time machine that I have on an external toshiba 750gb hdd as well. Thats the only thing on the external drive as well. I dont necessarily want to load my last Time machine backup as It had a messed up version of Windows 7 (missing ehternet/audio/pci drivers and wouldn't let me install them). I plan on doing the re-install completely through parralels 7 as well. Unless I should do it through Bootcamp. But if I do it through bootcamp can I still use parralles 7 to run both at the same time or would I have to just install it via parrallls to get this? (I was told at bestbuy that doing it htrough parrallels only makes it a "virtual drive" as doing it through Bootcamp makes it an actual partition... I already made a partion for it as well when I repartioned it to get it running again. I had all these problems once I wanted to try to install win7 from a previous win XP that I had running. The problem I think may be that I installed it through win XP rather than deleting ithe virtual machine? Also I was trying to "expand" the partition I had originally made for windows (65gbs because it wasn't enough) then I ran into all of these problems... Ugh... pleaseeee help meeeeee!!!
