Here i go ( sorry for my bad english, it's not my primary language. ) My macbook : it a 2006 macbook. System version : Mac OS X 10.6.3 Memory card : 2 x 1go DDR2 SDRAM HD : Samsung HM400LI 400Go What happened : My macbook was on the bed when the dog of my girlfriend dropped it on the floor. Problem : When I start my macbook, a folder with a interogation point appear. What I tried : Disconecting my HD, it did nothing so i put the snow leopard disk in the macbook, tried to restore but computer battery was low so my computer close. After this, my disk image was broken, unable to recover any data, I've erased everything on my HD with the disk utility fonction from the snow leopard disk. I tried to reinstall snow leopard on my macbook but after like 5-6 min an error message appear saying that the installation may not be completed because some folder cant be copied into the macbook. I tried with removing 1 memory card. And i have no external drive or any other mac for firewire. What should i do ?
