SSD Visible, Check Partition Layout

Question: diskpart list disk shows Disk 0 (476GB) and USB Disk 1 (14GB). Does this confirm VMD/RST?

Answer:

This result is actually useful:

Disk ###  Status   Size
------------------------
Disk 0   Online    476 GB
Disk 1   Online     14 GB

Conclusions:

✅ The NVMe SSD is visible in Windows PE ✅ The USB installer is visible ✅ The storage controller is not completely hiding the disk

So this is not the classic “Windows installer cannot see SSD because VMD driver missing” case.

The VMD theory becomes less likely.

The next thing to check is the partition layout.

Run:

diskpart

select disk 0

list partition

list volume

Send the screenshot.

Given your previous logs:

Setup Phase: [4]
0xC19001F4

and now:

Disk 0 visible

my suspicion moves toward:

1. Old GPT/EFI partition metadata (highest)

Your earlier error:

partition is of an unrecognized type
volume is offline

strongly points here.

If this is a clean install and you don’t need existing data, do:

diskpart

select disk 0

clean

convert gpt

exit

Then click Refresh in Windows Setup and install.

This will recreate:

EFI       FAT32    ~100MB
MSR       16MB
Windows   NTFS
Recovery  ~1GB

2. Check BIOS boot mode

In BIOS:

Boot Mode: UEFI
Legacy Boot: Disabled
CSM: Disabled
Secure Boot: temporarily Disabled

Windows 11 expects UEFI + GPT.

3. One more useful check

Run:

diskpart

select disk 0

detail disk

Look for:

Partition Style : GPT

or:

Dynamic Disk : Yes

If it says Dynamic, that explains the previous “unrecognized type” problem.

At this point I would not chase VMD anymore. Your SSD visibility proves the installer can communicate with the storage. I would check list partition and then likely do the GPT clean install.
