Missing NVSTOR.SYS

I have an Asus Vivobook 16 (Lunar Lake) laptop. I used Microsoft's Media Creation Tool to download a Windows 11 25H2 iso. I used NTLite to integrate the latest July 2026 Windows update and integrated all of the drivers from Asus's website for my laptop. When I boot the iso, I get a BSOD complaining that NVSTOR.SYS is missing.

I've created Windows images in this way before (integrating drivers and Windows updates) with NTLite and have never gotten any BSOD's about missing drivers. What is NVSTOR and why would this suddenly be missing from an image that came directly from Microsoft?
 
nvstore.sys is a driver file for NVIDIA storage controllers. But I think this is legacy stuff, like nForce and NRAID hardware of the past. The file exists in vanilla Windows 11 install. No idea why Lunar Lake laptop would need that though.

nvstor.sys driver errors are misleading. Nobody's owned a NVIDIA RAID controller for years (all those motherboards have disappeared). But you get this supposed error whenever you have a storage controller driver mismatch. Most likely your install image needs a specific version of the Intel RST drivers.

One quick check is see if your BIOS allows disabling RAID mode (to run as AHCI). If the same image installs just fine in non-RAID mode, then you will need to locate the appropriate Intel RST driver for this PC.
 
And if it works as described just above, there's no need to go through the hassle of hunting down the RST driver to set up RAID, unless you actually plan to use RAID on your laptop.
AHCI mode will work perfectly fine.

I wonder why manufacturers set RAID as the default mode, especially for laptops
 
Its the old "F6 Floppy" malarky all over again which i just cant be bloody bothered with now.
With these 2 laptops i see what OS will install without any hoodoovoodoo then get the correct driver from dell + lenovo and thats me done.

Ah, so it's RAID mode being on by default for "reasons" + Windows being stupid = confusing boot errors. Glad, I haven't ran into this nonsense in a long while. I thought NVIDIA storage was a thing of the past but I'm not familiar with recent Intel hardware so wasn't sure what that error could have meant.

Yeah, baffling indeed.
