    Look at the picture! What I want is simple, 100 mb is too small for EFI and I just want to make it 1GB. See that unallocated space in colored grey box, I want to move that near the EFI System Partition so that I could merge it. But now the problem is I can't because of Microsoft Reserved Partition which now left me with only
    1) Move MSR by Cloning then delete or
    2) Move EFI system partition by Cloning then delete

    Which one do you think should I take? or perhaps there is another way of doing it?

    :)

    now the problem is I can't because of Microsoft Reserved Partition, so I'm stuck. How should I enlarge it?

    How do I enlarge EFI System Partition?

    What make you think that 100MB is too small ? Basically this partition only contains BCD to boot Windows, only 34MB used.
    However, it is easier to use Macrium Reflect Free to get it done

    I agree with topgundcp, the EFI partition is normally large enough. If you boot another OS, like Ubuntu it adds more to the directory structure but the files are not large. Microsoft does recommend the partition be 260 MB for a 4 K drive.

    The MSR partition can be deleted and recreated with Diskpart, just leave enough room for it after you expand the EFI System partition.

    Clover doesn't fit in there. I want to install hackintosh in my system

    Okay. I've downloaded it. Now, How do I do it? what is the correct way to do it? Just plainly making disk image in the adjacent side then delete the original one?
