Heads-up: Acer RST driver ZIP breaks on Linux – Windows installer can’t find NVMe SSD

This isn't really a question — I figured it out after a lot of pain and wanted to share in case it helps someone else.

I have an Acer Nitro V15 ANV15-51, and I wanted to install Windows 11 alongside Ubuntu.
But when I booted the Windows installer, the NVMe SSD wasn't detected — it didn’t show up as a drive option at all.

The BIOS didn’t show any “SATA mode” option (AHCI vs RAID), so I assumed that part was fine.

Eventually, I realized the issue: I needed the Intel RST (Rapid Storage Technology) driver specific to this laptop.
Without it, the Windows installer can’t see the NVMe SSD because it's likely behind a VMD/RST controller.

So I grabbed the RST driver ZIP from Acer’s support page. All good, right? Nope.

Here’s the gotcha:

Acer’s driver ZIP uses backslashes (\) in file paths, because it’s made for Windows.
Linux unzip tools don’t treat those as folder separators, so when I unzipped it in Ubuntu, the whole thing flattened.

I ended up with files like:
VMD\iaStorVD.inf
HsaExtension\...
HsaComponent\...

Instead of proper directories like:
VMD
HsaExtension
HsaComponent

So when I clicked "Load Driver" in the Windows installer and pointed it to the USB,
it failed with "Error while loading driver" — because it couldn’t find the expected folder paths like VMD.

The Fix:

  • Manually recreate the directory structure.
  • Rename/move files into folders based on the original backslash paths.
  • After that, the driver loaded just fine, and Windows Setup saw the SSD.

I really hope this saves a poor soul hours of frustration.

And if any devs at Acer or Intel ever see this:
Please consider using forward slashes (/) in tar.gz drivers, or offer Linux-friendly versions.
Dual-booters exist! 🙃

Cheers!
