I am attempting to repair a 2009 Macbook.
At boot a grey folder with a question mark appears. In order to repair the disk, I have tried booting from a Lion Boot CD as well as a Lion USB stick. The Mac fails to recognize the CD when option is held at boot. The USB stick is recognized but eventually returns a blinking question mark when I attempt to boot from it.
Any suggestion on how to proceed, or any advice? Would this point to logic board failure? Should I try replace the internal HD with a working HD with install of OSX?
