    FYI, I built my own Recovery disk similar to KYHI's and it contains a set of tools such as Macrium Rescue, Mini Tool etc... The same as if you use Macrium Rescue disk and in your case, it won't do any good if you don't have those partitions that were deleted.

    Your SSD is a GPT disk. However, the result from list par looks very strange. The System partition is 200 GB and the primary partition is only 3086 KB. Normally the System Partition for a GPT disk is only 100MB and the primary partition is where your C drive is.

    @whs
    Please note his disk is GPT Type and you are refering him to the links for Windows 7 using MBR type disk. They are completely different, you cannot use bootrec/fixMBR on a GPT disk, there's no MBR to fix.

    @XweAponX
    Jagwar, just have both drives (plus a new empty drive) installed onto a PC. It's best to use Hiren's Boot CD to boot outside of your OS, Use Windows XP lite which is on the disk to mount an XP
    His disk is GPT while yours is MBR and Hiren's CD does not recognize GPT disk.

    Thanks for alerting me to the GPT detail. I missed that. I think I am getting too old for this stuff.

    Use KYHI's disk to boot and run Mini Tool Partition, right click->Explore on the 200GB System partition to find out if it is indeed the C: drive. You can tell by looking at the folders such as Windows, Programs Files etc... Apparently you did more than just deleting those partitions. If you still have the C: partition then we can proceed to fix it. If not, you are out of luck.

    Yes I already looked and it's definetly my C drive with my information on it. I now have the SSD with only 1 partition, the one with my C drive.
    I also currently have the same version (1511) of Windows 10 on another laptop, so I can take the boot partitions from it and hopefully copy them to my problematic SSD.

    OK. Is it the 200GB partition ? Please confirm. The dispart result you posted earlier has 2 partitions. One is 200GB the other is 3086KB

    Yes it's that 200GB (now 238.5GB) since I deleted the non working boot partition i had tried to recover and added unallocated space and extended the 200GB partition to that.

    So now I have the C drive (238.5GB) partition with my information on it. No other partition is existent.

    EDIT: Before making backup, you also need to set the ID of the 200GB partition to be Basic Disk, not System.
    OK.Boot up Macrium, Command prompt

    1. diskpart
    2. select disk 0
    3. select par 1 ------>200GB partition
    4. set id=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 override
    5. exit


    Next, create a backup image of the whole SSD to an external drive then use the link below to rebuild the first 3 partitions (450MB Recovery, 100MB EFI System, 16MB MSR partition) to the SSD then copy your C drive from the backup image to the SSD.
    The final result is also shown in the link. You'll end up with 4 partitions
    Old Recovery partition

    This is what should be as if you do a fresh install of Windows.

    You now have to shrink C by 566MB
    Move the OS partition to the right, so unallocated freespace is at front of disk

    then you can use Diskpart to re-create the missing partitions
