1	Overview
This document contains release notes for System Restore from Bootable Media Creator version 9.50. 
Using System Restore 9.50, you can restore a Windows computer from a BMR backup created using Windows Agent or Image Plug-in versions 8.30 to 9.50.
Note: BMR backups created using Windows Agent version 9.50 can only be restored using System Restore version 9.50 or later.
Before using System Restore, you must create recovery media using the Bootable Media Creator utility (BMC). Recovery media is a USB flash drive, CD, DVD or PXE boot server with a System Restore ISO image file. You must create separate recovery media for restoring systems with Windows Server 2025, Windows Server 2022 or Windows 11, and for restoring systems with Windows Server 2019, Windows Server 2016 or Windows 10. For more information, see BMC Requirements.
You can restore from a backup in a vault.

1.2.6	Limitations
•	On Windows Server 2025 and Windows 11 24H2 and later, BMC can only create recovery media for restoring systems with Windows Server 2025, Windows Server 2022 or Windows 11. 
•	System Restore can restore a maximum of 21 volumes from a source (protected) system to a destination system. If existing volumes are preserved on the destination system, the total of: 
o	the number of volumes preserved on the destination system
plus
o	the number of volumes restored from the source system
can be a maximum of 21 volumes. For example, if you want to preserve 3 volumes on a destination system, you can restore a maximum of 21-3=18 volumes from the source system using System Restore. After the system is restored, you can restore remaining volumes using Portal.
•	System Restore is not supported with 32-bit hardware or operating systems.
•	To restore a volume from an Image backup, the disk on the destination machine must have the same sector size as the original disk. For example, if a volume is backed up on a disk with 512 byte sectors, it cannot be restored to a disk with 4 KB sectors.
•	System Restore can only restore encrypted volumes (e.g., encrypted by BitLocker) if they were unlocked at the time of backup.
•	System Restore is not supported on VMware ESX 4.x.
•	UEFI backups cannot be restored to Generation 1 Hyper-V virtual machines, which do not have support for UEFI.
2	NEW FEATURES
Wider System Restore wizard
The System Restore wizard is now wider, providing more space to display information. On the Select Source and Destination Volumes page, more information can appear on rectangles that represent volumes. In previous versions, volume labels were often truncated, requiring you to view a tooltip to see the full label.
Restores blocked for unsupported operating systems
If you try to restore a system using recovery media that does not support the system’s operating system, a message now explains that the System Restore ISO file does not support the operating system and the restore cannot continue. Separate recovery media is required for restoring systems with:
•	Windows Server 2025, Windows Server 2022 or Windows 11
•	Windows Server 2019, Windows Server 2016 or Windows 10
Automatically maps volumes for systems with more than four disks
System Restore can now automatically map volumes from a backup to a destination machine when the source or destination system has more than four disks. In version 9.4x, the AutoMap feature was only available when the source and destination systems each had four or fewer disks.
Operating system support information in Bootable Media Creator
When you run the Bootable Media Creator on Windows Server 2025, Windows 11 24H2, or later, a note on the Creating Recovery Media page now explains that you cannot create recovery media for older operating systems on that computer. In previous versions, the option for creating recovery media for Windows 2019 and earlier, or Windows 10 was unavailable but it was not clear why BMC could not create recovery media for these operating systems.
Support for 10 TB disks
Using System Restore 9.50, you can restore disks as large as 10 TB from Image and Local System backups.
Support for BMR backups created using Windows Agent 9.50
System Restore 9.50 can restore systems from BMR backups created using Windows Agent 9.50. BMR backups created using Windows Agent 9.50 cannot be restored using earlier System Restore versions.
3	INSTALLATION NOTES
Before restoring systems using System Restore, you must create recovery media using the Bootable Media Creator utility (BMC). For instructions, see the System Restore User Guide. 
3.1	Installation Requirements 
3.1.1	BMC Requirements 
Windows Assessment and Deployment Kit (Windows ADK) and the Windows Preinstallation Environment (Windows PE) must be installed on a system before you can create recovery media using BMC. 
You must create separate recovery media for restoring systems with Windows Server 2025, Windows Server 2022 or Windows 11, and for restoring systems with Windows Server 2019, Windows Server 2016 or Windows 10. As shown in the following table, the required Windows ADK and Windows PE version depends on the operating system versions that you want to restore. Before creating recovery media, you must uninstall any other Windows ADK and PE version and install the required version.
Operating systems to restore | Required Windows ADK and PE version
Windows Server 2025, Windows Server 2022 or Windows 11 | 10.1.26100.2454
Windows Server 2019, Windows Server 2016 or Windows 10 | 10.1.17134
You can download Windows ADK and Windows PE from Microsoft and install them before running BMC, or when you run BMC.
General requirements for BMC: 
•	A computer running one of the supported operating systems listed in section 1.2 
•	CPU and RAM to meet the basic requirements of your operating system, as prescribed by Microsoft 
•	16-bit (or greater) video properties for optimal GUI display
•	A TCP/IP stack (for downloading Windows ADK and Windows PE, if they are not already installed on the computer) 
•	.NET Framework 4.8. If .NET Framework 4.8 is not present on the machine where you install BMC, you will be prompted to install it.
•	At least 100 MB of free disk space for BMC installation 
•	At least 7 GB of free disk space for installing Windows ADK and Windows PE 
•	At least 500 MB of free disk space for creating an ISO file 
The system drive requires free space to uncompress the packages (regardless of which drive the installation targets) for installation. The environment variables TEMP and TMP use %USERPROFILE% by default. Make sure that %USERPROFILE% points to a drive that has sufficient temporary space. 
3.1.2	System Restore Requirements
System Restore requires the following (minimum) hardware: 
•	AMD64/Intel 64 processors (No support for Itanium processors)
•	1 GB of RAM 
•	CD/DVD drive
•	800 x 600 minimum screen resolution
•	Network interface card for connecting to vaults
3.2	Licensing
System Restore does not require a license to restore. To back up to a vault, a valid license is required. 
For more information, contact your service provider.
3.3	Installation Files
Bootable Media Creator is available in a self-extracting installation kit: BootableMediaCreator-9-50-6732.exe
BMC produces bootable images with the following file names: 
•	System-Restore_win2022_11-9-50-6732.iso
•	System-Restore_win2019_10-9-50-6732.iso
To see instructions for using BMC to create the bootable image, refer to the System Restore User Guide. 
4	FIXES and KNOWN ISSUES
4.1	Fixes
Disks that are as large as 10 TB in size can now be restored from Image and Local System backup jobs. (5026721, 5029075)
4.2	Known Issues 
After you restore a computer that has more than one disk, NTFS disks that do not contain the system partition might be offline. This can occur after a restore with recovery media for Windows Server 2025, Windows Server 2022 or Windows 11.
WORKAROUND: Bring the NTFS disks online using the Disk Management utility or diskpart command interpreter in Windows. (4661387)
After you restore a computer, ReFS volumes might be offline. This can occur if the ReFS version used by Windows PE is not compatible with the Windows version of the restored computer. 
WORKAROUND: Use System Restore to restore the system without ReFS volumes, and then restore the ReFS volumes to the system using the Windows Agent. (2453667)
When you try to create recovery media using BMC, the process sometimes fails with an "Error code:1" message. This can occur due to the antivirus program on the computer where you are running BMC.
WORKAROUND: Do one of the following:
•	Run BMC on a computer with a different antivirus program. 
•	Uninstall Windows ADK, reinstall Windows ADK, disable the antivirus program, and run BMC again. (4358201)
When restoring a system to a Hyper-V destination machine, the order of the destination machine disks in the System Restore wizard is sometimes different than the order of the disks in the virtual machine settings. (3061217)
Removable USB drives on the source or destination system are counted in the number of disks on the system and could prevent the AutoMap feature from being available— even though removable USB drives are not backed up and cannot be used as restore destinations. 
WORKAROUND: If the AutoMap feature is not available, manually create a restore plan by dragging volumes from the source to the destination system. If the removable drive is on the destination system, remove the drive before the restore. (3156832)
If you restore a system from an Image backup, synchronize an existing Image backup job, and then run the backup job, the agent cannot find volumes to back up on the restored system. 
WORKAROUND: After restoring a system from an Image backup, edit the existing backup job and select the volumes again. The next backup will be a re-read. (2457765/EV-67024)
When creating recovery media using the Bootable Media Creator, an Insufficient memory error can occur if you try to add a driver with a long path and file name. (2459898/EV-56397)
If you try to restore a volume that is formatted with a 2K block size to a disk that has a 4K cluster size, the restore fails with the following error message: Cluster must be multiplication of the physical sector size. For more information, see the knowledge base article for this issue. (2466345/EV-32435)
When you try to restore to a destination disk with an OEM volume, the restore may fail with the following message: BMR is not able to get drive letter for mapped volume. Restore cannot proceed further. Please cancel and try again.
WORKAROUND: Delete all partitions from the destination disk. Change the disk format to GPT and then back to MBR, and then try the restore again. (2473919/EV-16204)
When mapping a volume from an Image backup using System Restore, even if you drag and drop the volume to a larger size destination, you may get the following message: Volume cannot be mapped. The destination is not of the same size. 
WORKAROUND: Right-click the volume, delete the partition on the destination disk, and try again. (26822)
If you seed BMR backups using a Quick Ship Vault, direct-attached storage, or disk, after your data is successfully imported into the vault, run a backup to the vault. Failure to do so may result in you not being able to restore your system. (26829)
Due to a Windows PE limitation, System Restore restores cannot run for longer than 72 hours. The Windows PE overview site states, "To prevent its use as a production operating system, Windows PE automatically stops running the shell and restarts after 72 hours of continuous use." (25803) 
If backup data is reformatted to an unsupported file system (e.g., FAT32), dragging and merging of an NTFS safeset to the reformatted volume may appear to preserve the destination format (e.g., FAT32). Associated restores, however, may fail. (25631)
Disk B may not be selectable for backup (Local System/Data Files). When an NTFS disk B is created in Windows Disk Management, it may not be selectable when you create a BMR-type backup job. (20867) 
System Restore may not retrieve the drive letter for a mapped volume if you drag and drop a large number of partitions (20 partitions, for example) to a GPT disk. The restore may not proceed further. 
WORKAROUND: Cancel and try again, selecting fewer partitions. (20854) 
System Restore may not preserve Quota Settings (user hard-disk space settings) for NTFS partitions.
WORKAROUND: Use the Image Plug-in instead of System Restore. The Image Plug-in preserves quota settings. (20669)
