USB Valid, Fix BIOS VMD | Generated by AI
Analysis Complete
Good news — your USB is already correctly made. Here’s what I found:
✅ USB is Valid (/dev/disk12 — 15.7 GB)
| Required File | Status | Size |
|---|---|---|
sources/boot.wim |
✅ Present | 586 MB |
sources/install.wim |
❌ Missing (expected — >4GB) | 7.1 GB original |
sources/install.swm |
✅ Present | 3.2 GB (part 1) |
sources/install2.swm |
✅ Present | 3.7 GB (part 2) |
sources/install3.swm |
✅ Present | 79 MB (part 3) |
boot/, efi/, setup.exe |
✅ All present |
Everything is in order. boot.wim is there. The install.wim was correctly split into 3 .swm files that Windows Setup handles natively.
🎯 The Real Problem (Not the USB)
Since the USB is fine, re-flashing it won’t fix the 0xC19001F4 error. The issue is almost certainly on the Lenovo Xiaoxin BIOS side:
Intel VMD Controller or Intel RST is enabled in BIOS
When VMD is on:
- Windows PE can see the NVMe (Setup starts copying files)
- After first reboot, Windows tries to boot from NVMe using in-box
stornvme.sys - That driver can’t talk through the VMD controller → drive disappears
- Windows triggers recovery → Setup sees this → aborts with
0xC19001F4
Step 1 — Fix BIOS First (2 minutes)
Before anything else, reboot the Xiaoxin → press F2 → look for:
| Setting to find | Change to |
|---|---|
| Intel VMD Controller | Disabled |
| Intel RST / Optane | AHCI |
| SATA Mode | AHCI (not RST/Optane) |
Save & exit. Then try the install again with the same USB — it should work.
Want to try that first before we rebuild the ISO?
