Hi Zeyad,

Hope you're doing well.

Deletion and reconstruction of recovery partition

Note: Important: It is best to make a BMR backup, checkpoint, snapshot, etc. before operation.

---delete-

1. Open the CMD command line and enter "diskpart"
2. Enter "list disk" under the diskpart path.
3. According to the "disk number" where your C drive is located, enter "select disk 0" (combined with the disk number seen in step 2, usually disk 0)
4. After you are prompted "Disk 0 is now the selected disk", enter "list partition"
5. Enter "select partition" (get the recovery partition number based on the size or type of the partition)
6. After you are prompted "Partiton is now the selected partition", enter "delete partition override"
7. When you see "Diskpart successfully deleted the selected partition", it proves that the deletion is successful. You can go to the disk manager to check whether there is excess space released.

Important: If you need to rebuild after deletion, we need to back up the winre.wim file before deleting it. Just copy it to the C drive.

---Recreate---

1. Reboot the server after delete the recovery partition, check if Operating system can normally start
2. Extend volume C
3. Shrink 550MB for the recovery partition
4. Right click on the unallocated space to create new NFTS volume. Assign a letter H:

Copy the WinRE image to recovery partition and enable WinRE by below commands:

mkdir H:\Recovery\WindowsRE

xcopy /h "C:\Winre.wim" "H:\Recovery\WindowsRE"

reagentc /setreimage /path H:\Recovery\WindowsRE /target

reagentc /enable

5. Remove the drive letter H and mark the partition as a recovery partition by below commands:

diskpart

list disk

select disk 0

list partition

select partition 2 (Replace the partition number with the one of H:)

remove

If UEFI (GPT) run command:

set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac

gpt attributes=0x8000000000000001

If BIOS (MBR) run command:

set id=27

exit

6. Run command "reagentc /info" to check if it takes affects.
7. Run command reagentc /boottore,then reboot server to check if we can boot into recovery mode.

Best Regards,

Ian Xue
