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.
- 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
- Create an image file from current recovery partition:
Dism /Capture-Image /ImageFile:C:\recovery-partition.wim /CaptureDir:O:\ /Name:"Recovery"
- 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:\
- Register the location of the recovery tools:
reagentc /disable
reagentc /setreimage /path N:\Recovery\WindowsRE
reagentc /enable
- 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
- Reboot the computer, now the new recovery partition should be working
- (Optional) Delete the old recovery partition:
DISKPART> select volume O
DISKPART> delete partition override
- (Optional) Check if the recovery partition is working:
- Show the current status:
reagentc /info
- Specifies that Windows RE starts automatically the next time the system starts:
reagentc /boottore
- Reboot the computer and do your stuff in Windows RE (eg. enter CMD and run some tools)
- Show the current status:
