Yes, I'm a muppet!Okay, so it sounds like the OS is hosed but that doesn't necessarily mean that your data is lost. If you take it to a authorised repair place, they might just swap out the hard disc and you'll lose it, so as someone else suggested, you need to get the data off the disc and reinstall the OS. Do you have the system discs ? Does the machine have a disc drive or is it USB ports only ? PS Buy a Portable Hard drive and Use Time Machine next time you Muppet !
Just saw this!Okay, having a disc would be best as you can boot of that and reinstall OSX - and it should leave any data intact as long as you don;t choose the option to wipe the disc. If you cannot find the boot discs, then if you know anyone else who has a Lion set you could use them. If not, you can create a USB Boot disc like this Make a Bootable Mac OS X 10.7 Lion Installer from a USB Flash Drive Its a quicker boot than of disc and I always carry a boot USB with me just in case. If you cannot manage to get a boot disc created then let me know and I'll see if I can create one for you - mine is a much more recent OSX version so I could reload it with Lion if you're desperate. You could collect from my office in Bur Dubai on Thursday if you are stumped.
