Q: Lost OS hard disc icons on opening

I have a mac book pro which doesn't have a disc drive. I installed windows on another partition (3) however it didn't have enough disc space for my download. I tried to alter this and deleted one of the partitions that only had 612MB which seemed to be clear (I only needed 60B). Since then when I open my computer and try to switch to OS the hard disc icons have disappeared. Im presuming its because I deleted the partition! Is there any one to recover this?

MacBook Pro with Retina display, iOS 8.1

    1. The 612MB partition is your local Recovery HD. IT should not be deleted if you ever want to use Command+R (Local Recovery)

    2. You Mac may not have an Optical drive, but must either have an internal or external disk to boot from.

    3. Your numbers need a bit of clarification (60B or 60MB or 60GB).

    4. What year/model is your Mac? The Recovery procedure depends on that and item 1 and any other changes to the disk partitioning.

    Can I resize the Windows partition after installing Windows?

    No. Back up your important files, then use Boot Camp Assistant to delete the old partition and create a new one.

    Hi,

    Im not quite sure I know what you mean!

     

    I didn't have enough disc space on my new partition (4) that I had created to install windows. I had allocated 20GB but this wasn't enough so I tried to extend the space but it wouldn't allow me so I deleted what I thought was empty space (although I can see from your answer I shouldn't have)

     

    Its Model A1502/ Yr 2013

     

    Sorry it was 60MB I needed


    If it is the recovery partition why would my icons for mac os disappear from the start up when Im logging in as that's my problem?

     

    Thanks for your help!

    Can you post the output of the following Terminal commands?

     

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

     

    The "sudo" commands require your password, which will not be echoed back to you. It may also warn you about improper use of "sudo" and potential data loss due to any such "abuse".
