    I cant seem to startup my macbook. I have tried every startupmodes there is... and have managed to delete the contents (which is okay. I dont mind that)

    When starting the mac the screen turns grey and if I try to use any other modes*a stop sign appears.

    Reset PRAM/NVRAM-

    After that boot to either your recovery partition, or an OS X install DVD depending on which one is applicable to you, load Disk Utility, Select your Startup Volume, Verify Disk, Repair Disk(if applicable), Restart.
