I seek help on my issue regarding removing Kali Linux from a dual boot with Windows 8.1.

These are the steps I followed to remove Kali Linux:

 1. Boot into Windows 8.1
 2. Delete the Kali Linux partition
 3. Extend the Windows 8.1 partition
 4. Reboot

After rebooting, grub rescue appeared.

I then booted my Windows 8.1 iso via USB (Using YUMI) and run `bootrec` command. However for: 

    bootrec /fixmbr
    
      successful

and after reboot, grub rescue was still there.

    bootrec /fixboot
    
      element not found 
    
    bootrec /rebuildbcd
    
      element not found

Then I tried to go to Diskpart and tried to set the partition to Active, but the output states that the partition is currently ACTIVE.

I even tried to command in grub rescue

    ls
    (hd0) (hd0,msdos1) (hd0,msdos2) 
    set boot=(hd0,msdos2)
    set prefix=(hd0,msdos2)/grub/boot
    isnmod normal
    
    error: unknown filesystem

    normal
    
    Unknown command 'normal'

Now I can still access my Windows 8.1 after booting into Super Grub2 Disk and boot Windows 8.1, but how should I fix it or remove grub?
