I’m trying to migrate my system from a small M2 NVME SSD to a larger and faster one, but I’ve had no luck using various disk cloning/imaging apps (True Image, Macrium Reflect, AOMEI Backupper, Paragon Backup & Recovery) to clone the old SSD to the new one. All of the OEM partitions on the destination SSD become “normal” primary partitions instead of OEM partitions, even when using sector-by-sector copy and no resizing options. This may be why the OEM recovery is no longer functioning, although the Windows system itself is still working fine. It’s possible that the BCD information has been affected, but I’m not sure how that could happen as a result of the cloning process. Is there a way to properly clone these OEM partitions to the new SSD?

Note: Recovery works again if I connect the old SSD through an M.2 to USB enclosure. This suggests that the BCD information is somehow pointing to the partition on the old SSD.
