Question: Check the Windows installation failure from setuperr.log screenshot.

Answer:

I checked the screenshot. The important lines are:

CUnattendManager::Initialize(90): Result = 0x80070490
CMOSetupOneSettingsHelper<...>::InitializeSettings(324): Result = 0x80072EE7
CSetupHost::InitializeOneSettings(1606): Result = 0x80072EE7

...
CSetupManager::ExecuteInstallMode(...)
CSetupHost::Execute(564): Result = 0xC19001F4

The final error:

0xC19001F4

is the real failure code. It means Windows Setup failed during the installation workflow, but the screenshot alone does not show the original trigger.

The earlier errors:

0x80070490

= ERROR_NOT_FOUND (something expected in setup configuration was missing)

0x80072EE7

= name resolution failure (DNS/network lookup failure)

These are usually secondary. The important part is that setup entered a failure path and rolled back.

From your previous context (Lenovo Xiaoxin + USB install + recovery environment message), the likely causes are:

1. Wrong USB install media method (most likely)

You created the USB on Mac using FAT32 + copied files. Windows 11 25H2 ISO has:

sources/install.wim

which is often >4GB.

If you split WIM incorrectly or the ISO copy was incomplete, setup can fail later.

Check USB:

Boot back to Windows PE command prompt:

dir D:\sources

You should see:

install.swm
install2.swm

or:

install.wim

not a missing file.

2. Disk partition state problem

Earlier you had:

partition is of an unrecognized type
selected volume is offline

If the Lenovo SSD still has old metadata:

Open command prompt:

diskpart

list disk

select disk 0

clean

convert gpt

exit

Then install again.

Warning: clean destroys all partitions.

Because:

0x80072EE7

appears.

During Windows 11 setup, avoid online account setup.

At the OOBE stage:

Press:

Shift + F10

then:

OOBE\BYPASSNRO

Reboot and choose:

I don't have internet

What I need next

The screenshot is only the tail of setuperr.log. The most useful part is earlier.

Please send:

C:\$WINDOWS.~BT\Sources\Panther\setupact.log

around the first occurrence of:

Error

or run:

findstr /i "error failed rollback 0xc190" setupact.log

Also tell me:

  1. Did it fail during:

    • copying files %
    • installing features %
    • first reboot
    • final “getting ready” phase?

  2. Is your USB created with:

    • wimlib-imagex split install.wim
    • Rufus
    • Etcher
    • manual copy?

My suspicion currently: USB media / install.wim handling or old SSD partition metadata, not the recovery-environment line itself.
