How to Create a Missing System Reserve Partition (SRP) -
Description
You have omitted to protect the SRP partition, or it was in a different protection schedule than OS(C:\) drive of your Rapid Recovery protected Windows 2008R2 or later agent. You are forced to do a BMR or a Virtual Export. The recovery operation goes well, but the exported machine does not boot. You need to find a way to quickly re-create the SRP. -
Résolution
To recreate the SRP:- Boot from a WinRE environment (Windows Install Disk would also work), either press combo keys SHIFT+F10 or navigate through the various menus to get to a Command Prompt option. Open a DOS Command Prompt.
- Run DiskPart
- At the DiskPart prompt type:
list volume
Note that the SRP partition has actually been created but it is reported as unformatted. - Make note of the drive letter for:
- the SRP (which is shown as a raw partition)
- the system volume (contains the Windows OS)
- the CD you have used to boot.
Note: For the following we assume that the SRP is shown as C:, the System Volume as F: and the CD Drive as G: - Run
list disk - Identify the disk containing the SRP & the OS and guiding yourself by the size of the drives. We assume that it is disk 0.
- Run
select disk 0 - List the disk's partition running
list partition - Identify the number of the SRP partition (it should be 1) and select it running
select partition 1 - Format the SRP running
format fs=NTFS label=”SRP” - Set the SRP Partition as active running
Active
(Note that it is marked with an * now, when running list partition) - Exit DiskPart typing exit and hit enter
- Change the focus from X: (the default) on the SRP partition (c:) by running:
c: - Create a folder called Boot running:
Mkdir Boot - Copy the content of the boot folder on the system partition (F:) to the new folder:
xcopy f:\windows\system32\boot c:\boot /e /h - Copy the bootmgr from the root of the CD (g:\)
copy g:\bootmgr - Run the following commands
- Bootrec /Fixmbr
- Bootrec /Fixboot
- Bootrec /rebuildBCD
When it asks to add installation to boot, print Y and hit Enter. - Close the Command Prompt and reboot the machine, it should boot all the way now.
Alternatively, you can try the following after step 16:
- Change the focus back to drive X: and change the location to x:\sources\recovery (Note: This can only be performed if booted up from the windows CD/iso)
X: - Run
cd \sources\recovery - Run
startrep
Note: In some rare instances you need to redo the boot sector.
