  • Forma fs=fat32
  • list vol     (write down the volume of the new partition in a safe place)
  • select vol 3      (Supposing that volume no. of “EFI partition” you earlier noted down was 3)
  • assign
  • List vol    (and check which letter is assigned to the 200 MB EFI partition).

Note down the letter (ltr). You’ll also need to recognize the ltr of the volume containing your Windows partition (just look for Boot written in the Info column).

Now type: bcdboot C:\Windows /l en-gb /s B: /f  ALL; assuming that C is the letter for Windows partition in addition to B for the EFI.
