May 20, 2018 · Why is Mark Partition Active greyed out in Disk Management? - posted in Windows 10 Support: Hi, Yesterday I used Disk Management on a couple of 16GB USB flash drives to create a New Simple Volume ... I wll be unable to backup MSR partition. This means if i decide to restore this disks I will be unable to creat or resotre MSR (Microsoft Reserved Partitio) partition. Becouse of Acronis have no ability to create ESP/MSR I will miss this partition. I know I can creat this partitions using diskpart.
Server 2003 and Server 2008 both contain a DISKPART tool, which can extend an NTFS volume to use the rest of the space. This is not a full-featured partitioning tool, as it can only extend a partition into unallocated space that lies just beyond it.
