Jauhar I was suffer with exact same situation.

It happens if you're using UEFI and your OS disk doesn't have EFI and MSR partition.

You have to recreate both of partition.

before you create it, you have to secure at lease 500MB from OS disk.

 

Open command>

diskpart

select disk 0(your OS installed disk)

create partition efi size=300
format quick fs=fat32 label="system"
create partition msr size=128

 

hope it will help

Hi Johnny
I'm having the same issue and wonder if I need to do the same. In your above command, what're the size 300 & 128 in, KB, MB, GB? Thanks.

Below is the output of my Diskpart info, please tell me if you observe the issue too:

    Hi Ken
    It's MB. Here is my Disk Status.

    DISKPART> select disk 0

    Disk 0 is now the selected disk.

    DISKPART> list partition

    Partition ###   Type                   Size          Offset
    -------------     ----------------   --------    --------
    Partition 1        Primary              953 GB       32 KB
    Partition 2        System              300 MB     953 GB --> EFI Partition
    Partition 3        Reserved           128 MB     953 GB --> MSR Partition

    it works your partition style should be GPT.
    you can find out your partition style from input 'Get-Disk | ft -auto' in Windows PowerShell.
