    No Operative System boots. I deleted EFI Partition





    Hello friends. Let me tell you what happened. In my laptop currently I have two discs. One HDD 1TB and a SSD 256GB. Before having my SSD drive my laptop used windows 8.1 in the HDD drive, where I initially had two partitions one for windows and another one for documents and data. When I bought my SSD drive I installed windows 8.1 on it to test it and I was using my computer with both of these operating systems normally. I had always planned for cleaning my HDD drive and just leave it as a drive for Data and run windows 8.1 installed in the SSD.
    To complete one school assigment I installed Linux Ubuntu 14.04. However, to do so I created a new partition
    of 105 GB from the free space I had in the HDD drive and installed it there. It worked fine with no problems, but at that time I had three Operating Systems in my laptop which was a waste of space. My HDD drive had a lot of partitions, so I deleted all the partitions that didnt have my data including the original Windows 8.1 and the EFI partition, which I know now it is used for botting everything. Hence, in that disc the only thing left was two partitions Ubuntu and my data.

    Now nothing works, none of my OS boots. My SSD drive has Windows installed but it does not have anyh bootloader. My HDD drive has linux installed but the grub doesnt work either. I tried to fix using some softwares I checked on the internet called Supergrubdisk and Rescatux but nothing has worked. Please help me with this problem I want to get the EFI partition back and run both operating systems windows from the SSD accesing my data partition in the HDD and Ubuntu in the HDD as well. I dont want to reinstall from zero and lose my data if possible,

    Sorry for the big post but I wanted to explain in detail to avoid confusion and random useless questions.

    Thank you in advance.

    diskpart
    list disk
    select disk 0
    list partition
    select disk 1
    list partition

    post a pic of diskpart windows (info)

    I assume the SSD has just windows 8.1 on it and the HDD has all the boot and recovery files on it...
    If that is the case - you should be booting to the HDD and not the SSD
