STATUS_VOLMGR_DISK_LAYOUT_NON_BASIC_BETWEEN_BASIC_PARTITIONS
STATUS_VOLMGR_DISK_LAYOUT_NON_BASIC_BETWEEN_BASIC_PARTITIONS identifies an ordering problem in a legacy disk layout. It is not the same as the Windows distinction between a basic disk and a dynamic disk; this check concerns the partition entries and their ordering in the layout submitted to Volume Manager.
It commonly matters when software reconstructs, migrates, or writes an MBR layout rather than using ordinary high-level partitioning tools. Reordering entries without understanding the partition table can make an existing installation or recovery path unbootable.
What to inspect
- Record every partition entry in on-disk order, including hidden, OEM, recovery, extended, and vendor-specific entries.
- Confirm that the request was built from the current physical disk, not from a stale clone or a drive-letter inventory.
- For a migration, validate the resulting MBR/GPT design before any write and keep a sector-level backup of the original partition table.
