2006 macbook give me flashing folder with question mark without disk
The folder with question mark on start up means that the Mac is unable to locate your boot drive.



Many possible causes:


Corrupted boot disk.


You can try Disk Utility using a boot via external unit (CD-ROM, external HDD, USB) to repair the disk. If you are unable to see the primary disk via Disk Utility follow the two possibility below.

HDD broken.


Replace your HDD and install a fresh copy of OS X or try to extract your data form the broken HDD and move it to the new one.

HDD SATA cable disconnected / broken.


Your HDD is connected via SATA flat cable. Open your Mac, check this cable if it is disconnected or try to replace it.
