    Hi.

    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- https://support.apple.com/en-us/HT204063

    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.
