The documentation I've read suggests that it's the area where partition information is stored, which of course sounds important. And yes I'm not sure what the ramifications would be of not having one. Although I don't see why it wouldn't create an MSR partition given that it just requires another 16 MB you could gain by shrinking the Windows partition a tiny bit more.

But I may be wrong, or maybe something has changed. As for the MSR partition, I only used the MBR2GPT utility once shortly after it arrived (can't remember which Win10 release introduced it), and I seem to recall it creating both the EFI and MSR partitions. But as you say, having the EFI partition after partitions you actively work with and might want to resize can create some inconveniences. Instructions, documentation and other important information about viBoot is available in this KnowledgeBase article: Introduction to Macrium viBoot.It's true that the EFI partition doesn't HAVE to be the first partition on disk, in fact until Windows 10 2004, the default Windows Setup behavior for clean installs onto empty disks was to create the WinRE partition first, then place the EFI and MSR partitions after that. Windows 8 and above (64bit only) / Windows Server 2012 R2 and above. The type of virtual machine to create is automatically detected by viBoot based on the virtualization software installed on the host. Macrium viBoot is now built upon new technology that allows it to instantly present a Macrium Reflect image file as a Microsoft Virtual Disk (.VHDX) or VirtualBox (.vmdk) file. At an enterprise level, you could recover an entire network environment in minutes. Macrium viBoot enables you, to instantly create, start and manage Microsoft Hyper-V and VirtualBox virtual machines using one or more Macrium Reflect image files as the basis of the virtual machine storage sub-system.Īt a minimum, viBoot enables you to boot into the images you have made using Macrium Reflect, for validation purposes, or to retrieve data from old applications stored on a bootable image.
