    Cannot create a partition of Unallocated space !!!


    Hi,
    A few weeks ago i accidently deleted my entire hard drive using diskpart>clean command from cmd.
    After a lot of work, finally I restored all volumes and files like before!
    After the restoring, the pc was not booting up. So I had to insert a windows 8 disc and use its repair tools to make my laptop boot normally. The problem that I'm facing now is that recovery partition isn't recognized (it says : Could not find recovery environment), and when I try to create a new partition I get the message : "you cannot create a new volume in this unallocated space because the disk already contains maximum number of partitions".

    here is a screenshot of Disk Management:Click image for larger version

    Does anyone have any idea how to fix this?

    MBR partitioned disks will only allow 4 primary partitions.. If you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it. Or convert it to GPT. What
    That's my guess.

    type> diskpart
    type> list disk
    type> list volume
    type> exit
    type> reagentc /info

    I had to disable secure booting and enable legacy support from bios configuration to boot successfully. If I enable secure booting I get the message : "Selected boot image did not authenticate"

    Thanks for the reply,
    can I CONVERT a partition into "extended" or I have to delete it first and than to create a new one as extended?
