This article explains how to work with the Advanced Partitioning schemes available in the Datto USB BMR environment. It assumes that you have already completed the steps in USB Bare Metal Restore: Booting the target machine from USB, and that you are in the Advanced Disk Utility.
If you are performing a Bare Metal Restore of a Linux system, keep the following differences in mind while you go through this process:
- The file system type will be ext2, ext3, ext4, or xfs, unless the partition is for swap, in which case the file system type will automatically populate in the partitioning interface.
- If there is only one partition, it will be bootable by default.
- If there is a separate
/bootpartition, set it to be bootable, and make sure it is the first partition listed.
By this point in the process, you should see the Advanced Disk Utility environment shown in Figure 1.

Setting up an OS partition
Your next steps depend on whether you want your target machine to use Master Boot Record or GUID Partitioning Table (GPT). The advantages of GPT include EFI booting and creating volumes over 2.2 TB in size. Make sure that you have hardware that supports EFI before you choose this option.
Setting up an MBR OS Partition
To set up an MBR OS partition, follow these steps:
Delete the existing OS partition and any existing system reserved partition, as shown in Figure 2.
Figure 2: Delete a partition
Click Add Partition. Create the OS partition with an MBR partition scheme. Set the Type to Primary, and the size to be 20% larger than the original OS drive that you are restoring. Set the File System to NTFS.
Figure 3: Creating an OS partition (Windows)
Click Bootable. Then, set the Restore Mount Point to the volume you are restoring from.
If you need to create a data partition, go to the Setting up a data partition section below.
If you are done with partitioning, click Accept.
Then, proceed to the article USB BMR: Data Transfer.
Setting up GPT OS partition
To set up a GPT OS partition, follow these steps:
Delete all partitions involved in the boot process. This includes the EFI system partition (512 MB), the MSR partition (128 MB), and the Windows partition.
On the physical drive that you want to use for the OS, set the Partition Scheme to GPT, as shown in Figure 4.
Figure 4: GPT Partition Scheme
Click Add Partition, and create a primary GPT partition with an EFI file system format. Set the Size to 512 MB by entering .512 in the Size field, as shown in Figure 5.
Figure 5: EFI Partition
Click Add Partition again, and create a Microsoft Reserved partition with an MSR file system format. Set the Size to 128 MB by entering .128 in the Size field, as shown in Figure 6.
Figure 6: Microsoft Reserved Partition
Click Add Partition, and create the OS partition as the Primary boot partition. Set the size to at least 20% more storage space than the system you are restoring. Set the file system to NTFS, check the Bootable box, and select the Restore Mount Point of the volume you are restoring. See Figure 7.
Figure 7: OS Partition
Click Add to add the partition. You will see the window as shown in Figure 10.
If you need to create a separate data partition, go to the section Setting up a data partition.
If you are done with partitioning, click Accept. Then, proceed to the article USB BMR: Data Transfer.
Setting up a data partition
To set up the data partition, follow these steps:
Delete the existing data partitions that you wish to overwrite, as shown in Figure 8.
Click Add Partition, and create the new partition scheme in MBR or GPT format, as desired. See Figure 9.
Figure 8: Setting the Partition Scheme
Choose NTFS for the file system. Make the size at least 20% larger than the existing data set that you want to restore.
Figure 9: Adding a data partition
If you want to set up another data partition, repeat the steps in this section.
If you are done with partitioning, click Apply. Then, proceed to the article USB BMR: Data Transfer.
