    I have googled for solution and few of them have tried but none of them worked.

    Here is my problem:
    I cant start my macbook (mid 2010). When I press the power button, the apple logo appear as well as the spinning bar, for about two minutes a progress bar appeared (like boot from safe mode), however for a while the bar disappear and without loading any progress then for another while it turned off automatically.

    I have tried to boot from mac install disk, after I pressed "c" while booting the apple logo appear but not the spinning bar, and then I am stuck at it. I can hear the disk stopped to load after about 15 mins and nothing happened after.
    I also tried to boot from the disk warrior but same situation happened, nothing happened even i placed it for about 30 mins

    I have tried to boot at verbose mode and it said
    "Incorrect block count for file"
    "invalid sibling link (1 instead of 0)"
    "rebuilding B-tree catalog"
    "The Macintosh HD could not be repaired"

    Also "fsck_hfs -f /dev/disk0s2" in single user mode wont work as well:(

    Any idea please?

    My mid 2010 MBP had the same thing happen. The hard drive needed to be replaced. Im glad I had Apple Care and TimeMachine backups. Did you try an archive and install of your OS?

    I'm having the same exact problem. I put a new hard drive in and it still won't boot. Tried firewire running in target mode used disk warrior and it did fix problems but it still won't boot.:mad:

    As always, try to reset your PRAM and NVRAM, attempt to boot while holding down the ALT key, and finally, attempt booting from external drive, and selecting the startup disk.

    cmd+option+P+R: hold it down at boot, listen for the boot chime 3 times to reset both PRAM and NVRAM.
