Warning 1: You must know what the following commands do before you execute them. Check the link above and MS’s documentation for diskpart, dism and reagentc.

Warning 2: Check disk numbers, partition numbers and volume letters carefully before executing commands.

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)
