    Deleted all partitions except system/os

    Hello Everyone,

    I deleted all my partitions except the Windows os/system partition. Is there a way to recreate the EFI and system reserved partitions?
    Now all I have is:
    1.30GB unlocated
    119GB ntfs (os)
    178GB unlocated

    Thanks in advance

    If that doesn't work, you can:

    1. Make an image backup of the OS partition using Macrium Reflect Free.
    2. Boot a Win 8 install DVD or flash drive and do a clean install, deleting all partitions then install to the unallocated drive. The installer will create the necessary partitions.
    3. Once the clean install is done, restore the backup image to the OS partition.
    4. Run the Fix Windows boot problems task.
    5. Reboot and all should be as it was with the correct partitions recreated for you.

    I've done this several times on Win 10.

    Boot from your installation disk, delete all partitions until all you have left is Unallocated Space. Continue to install Windows without creating partitions or formatting. All should be well thereafter. Once Windows is up and running use EaseUS Partition Master to partition your HDD.

    Sometimes it may happened that unknowingly you may hit for the deletion of partitions from the hard drive while performing an another task, if it is happened with you, then don’t be panic any more as now it is much simpler to recover deleted partition than earlier. Have a look on this site: Best Partition Recovery | Recover Partition Data and know how simple it is to perform partition recovery even on the latest version of the Windows.
