Hello, I have MacBook Pro mid. 2009 and its not booting. My mb was in a sleep mode, when I open'd up it asked me to type in password but I could not do that because instead of a mouse it showed me spinning mouse logo so I turn it off with power button. When I turn it on it just showed me apple logo and spinning bar. At first I thought it was OS problem so i decided to reinstall, but it kept showing that he cant unmount the HDD and disk utility finds the HDD but as well it is not allows me to do any changes. The HDD is is working I all ready tried it on other laptop.
