It's completely normal to see these extra partitions after moving Windows to an NVMe SSD, and you're better off leaving them exactly where they are.
The 16MB MSR (Microsoft Reserved) partition is a byproduct of the GPT partition style used by modern NVMe drives. Think of it as a "placeholder" Windows keeps for future disk management tasks, it doesn't have a file system, which is why it looks empty.
As for the EFI and Recovery partitions, they are functional:
- EFI: This is your bootloader. Without it, your NVMe won't know how to start Windows in UEFI mode.
- Recovery: This contains the WinRE (Windows Recovery Environment) tools. If your system ever fails to boot, you'll need this to run a Startup Repair or access the Command Prompt.
If your old HDD was MBR, the restoration software likely handled the MBR-to-GPT conversion to ensure the SSD is bootable on a modern UEFI system. Deleting these to "clean up" might save you less than 1GB of space, but it's a high-risk, low-reward move that will likely break your boot path.
As long as the system is booting fine, just ignore them in Disk Management.
