Cannot boot. Just show a circle with line through it. And cannot mount. I don't have lion cd. I can't afford to lose my files. MBP 2011 Lion version 10.6. I tried using terminal and fsck but fail.Please help
I forcefully shutdown my MBP 2011, but after it restart and I login, it shows the apple logo. But after sometime it will change into a circle with Aline through it. And it will stock there and do nothing. Then I try to boot in safe mode by pressing shift button when starting the system but it did not work. I tried booting in apple testing mode and it did and test all my hardware and found no problem. Then I tried to boot by pressiing command plus R key. And I was able to boot to disk utility menu. Unfortunately I can see my drive but when I click it I can' go to the first aid tab. And when I click the first disk at the up, it's I will be able to go to first aid tab but when I click repair it's going to come up with error: storage system verify or repair failed. Then I try to use terminal, I have used diskutil command but it doesn't work I try to use the fsck too, it still doesn't work. Please somebody help me. I don't want to lose my files.
