Recreate Recovery Partition

1. Use diskpart to find current recovery partition and assign a driver letter(eg. O) to it:

   DISKPART> list disk
   DISKPART> select disk <the-number-of-disk-where-current-recovery-partition-locate>
   DISKPART> list partition
   DISKPART> select partition <the-number-of-current-recovery-partition>
   DISKPART> assign letter=O

2. Create an image file from current recovery partition:

   Dism /Capture-Image /ImageFile:C:\recovery-partition.wim /CaptureDir:O:\ /Name:"Recovery"

3. Apply the created image file to another partition(eg. N) that will become the new recovery partition:

   Dism /Apply-Image /ImageFile:C:\recovery-partition.wim /Index:1 /ApplyDir:N:\

4. Register the location of the recovery tools:

   reagentc /disable
   reagentc /setreimage /path N:\Recovery\WindowsRE
   reagentc /enable

5. Use diskpart to hide the recovery partition:

   • For UEFI:

     DISKPART> select volume N
     DISKPART> set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
     DISKPART> gpt attributes=0x8000000000000001
     DISKPART> remove

   • For BIOS:

     DISKPART> select volume N
     DISKPART> set id=27
     DISKPART> remove

6. Reboot the computer, now the new recovery partition should be working

7. (Optional) Delete the old recovery partition:

   DISKPART> select volume O
   DISKPART> delete partition override

8. (Optional) Check if the recovery partition is working:

   1. Show the current status:

      reagentc /info

   2. Specifies that Windows RE starts automatically the next time the system starts:

      reagentc /boottore

   3. Reboot the computer and do your stuff in Windows RE (eg. enter CMD and run some tools)
