EBIOS read error
My Macbookpro will not start coming up with EBIOS read error: Error 0xbb block 0x142bc sector 0. The same happens while trying to start with CD. After 4 time nothing happens at all. Internet recovery produces an error (non of the options worked even I have backups) and suggests to start the application again. Can somebody tell me what is going on. By the way an update of the firmware 1.7 was waiting - but I did not say update. Did it happen anyway and is causing problems. Any suggestions?
MacBook Pro, OS X Mountain Lion (10.8.4)
