I am experiencing an issue where the recovery partition is visible in “This PC” after restoring my PC from a disk image, which should not be the case. Before restoring the PC, I used DISKPART to remove the drive letter from the recovery partition. I want to prevent Windows from reassigning a letter to the recovery partition after restoring the PC from the disk image.

I am using Windows 10 (64-bit) version 1903 (May 2019 Update) and have a MBR disk with a Standard BIOS that does not support GPT disks. I have tried using the GUID method, but it does not work because I have an MBR disk. I have also tried using the “attributes volume set nodefaultdriveletter” command, but it does not have the desired effect as Windows continues to assign a drive letter to the recovery partition after the system restore.

I used the Windows 10 built-in “Backup and Restore (Windows 7)” utility to create an image of the “C” partition and used the Windows 10 version 1903 (May 2019 Update) installation CD to restore the system. I am unsure if this procedure changes the attributes of the recovery partition, but I have verified that the “nodefaultdriveletter” attribute remains even after the system is restored. However, the drive letter is still being reassigned to the recovery partition by Windows.

I have tested that both a logical recovery partition located within an extended partition and a primary recovery partition have the same behavior on my MBR disk. I have also determined that the startup task method may not always work as the volume number of the recovery partition can change depending on the devices connected at the time of the restore, and it is also not useful to identify a volume based on certain features as there can be multiple volumes with the same characteristics and volumes can have the same label even within a single disk. Since I have an MBR disk, the partitions cannot be uniquely identified using the GUID. The latest BIOS version supported by my motherboard does not have GPT disk support implemented.
