NO_SUCH_PARTITION

Missing partition object in storage path for NO_SUCH_PARTITION

NO_SUCH_PARTITION is bug check code 0x00000043.

This bug check is about a kernel storage reference to a partition that cannot be resolved. It is usually tied to disk layout, partition enumeration, filter-driver state, or a stale reference after storage topology changed.

How to read it in a dump

The dump stack should show whether the failing path is volume manager, disk class, partition manager, file system, or a storage filter.
Arguments are secondary to the object and device stack visible in WinDbg.
This is different from INACCESSIBLE_BOOT_DEVICE; it does not necessarily mean the boot volume was lost.

What to check

Check disk/partition changes, virtual disk attachment, SAN path changes, and storage filter drivers.
Inspect device objects, volume manager state, and recent disk reconfiguration.
For boot-time failures, compare BCD, firmware boot order, and partition table visibility.
