Macbook with 10.6.8 wont boot

Sorry for my english.

What i've got:
Macbook Pro 17" Core i7
SSD Crucial M4 with latest firmware
Mac OS 10.6.8

Few days ago my drive became full and system won't boot: blue screen with curcor and nothing more.
Disk utility returns error and i should backup data and reformat drive.

It was unable to clone drive image so i made backup via teminal command cp -R.

I've installed Mountaion lion and tryed use migration utility to restore my data. Utility freeze on calculation "Users" folder and won't import Users data.

So i've installed 10.6 from DVD that i've got my macbook. Everything ok. migation utility import all data with programms and settings. All works, disk utility check found no errors. But 4-5 reboots after that and system won't boot: flower for 1 minute and them deny boot icon.
Rebooring in verbose mode prints coniniusly "still waiting for root device".
Google that error shown me hakintosh community, but i've got macbook.



Then i unplug drive from sata cable and plug into usb to sata adapter - and system boots without errors.

What should i do for fix it?

Thanks.

 

Downloaded 10.8 iso from thepiratebay.se and installed Mac OS without cleaning harddrive.

Now system works fine.

I feel that some system file were corrupt and i've refreshed them.
Maybe it will help somebody in future.
