    I was trying to fresh-install my os, so i started on recovery (pressed command+r) and I erased my drive. Than after reboot i click the option "reinstall osx", but when it gets to the point I need to choose where to install osx, i don't have any options. so i went to disk utility, i clicked "verify disk" and "check disk" on my main drive (the ssd drive) and it says everything is ok. The weird thing is that i only have two tabs: 'first aid' and 'partition'. on partition i cant do enything. it looks like it is not partitioned and it is not ready for startup, because also when i click 'choose start up disk' i dont have any option, blank.
    when im on disk utility there is also another weird thing: I see it only on one line:

    that how it looks when it is normal (on my macbook pro):

    i think it is locked or something.
    any one has any idea?
    thanks ahead, and sorry for the English. i'm not local :)

    Hey there,
    I am assuming you installed Yosemite on your machine. When you were clicking through the setup you enabled FileVault.

    Select the second drive partition on the left column of disk utility. Click the erase tab on the top portion of the disk utility window.

    once the partition has been erased, select the hard drive on the left column again, click the partition option in disk utility and re-partition the drive. Once the drive is re-partitioned, you will be able to reinstall OS X on to the new partition of the drive you just created.

    Feel free to reach out if you need anything else.
    Make sure you have your data backed up.
    THIS WILL ERASE YOUR HARD DRIVE.

    Alright, now I understand what it is you are saying.

    Here is what you will have to do;

    You will have to use terminal to zero out the drive. When the drive has been zero'd out, it will create a generic partition. At this point it will allow you to repartition the drive and allow you access back to the disk.

    You are right, it looks as though the disk is locked. Do a google/youtube search for how to zero out a drive using terminal.

    Solved. I just had to 'force' re-erase by terminal window. Thanks for the help anyway.
