Did you try starting the MacBook by holding down the command + R key, then run disk utility on your hard drive to repair/verify it. If you are unable to see the hard drive in disk utility then you will need a new hard drive. Take a look at this link, http://support.apple.com/kb/HT1782

Thanks for your fast reply.
Yes, I've tried cmd-R. I get a "blue screen" with vertical lines. Pretty weird.
I'm unable to access the Disk Utility.
Do you think the HD is damaged?

Hi, can you hear the hard drive sound when you start your MacBook, if not I think you should replace your hard drive. If you MacBook is only a week out of warranty you may be able to get it covered, take it to an Apple store and let them take a look at it.

I am having the same problem but I can hear my hardrive. I am unable to reach disk utility, I have tries a safe boot and resetting with Command Option P R. No luck. When I tried disk utility with the disk in, I was taken to a new window to install. Does this mean everything has now been erased?

Is your backup a boot drive? If so you can access the internal HDD and determine its status and perhaps repair it. If not I suspect that Eric Ross is correct, a new HDD is in order.

Eric, this is werid, but I love you dude!!!! My mac couldn't boot up and never read in any of the 40 forum pages I've browsed about the cmd + R comand. Thank you so much! Now I finally can use disk utility. Was resigned to lose my data and maybe my mac, since I thought my HDD was screwed(couldn't boot to safe mode, tho it could do fsck, it didn't work properly) Thanks again =D
