Recovery environment not root cause

Question: Analyze this setupact.log screenshot — is “User has requested to launch the recovery environment” the root cause?

Answer:

This screenshot gives a clearer picture. The important sequence is:

CInstallUI::SwitchToProgressPage
CSetupResponseTemplate<class IDlpResponse>::ExecuteRoutine: Next button clicked.

...

User has requested to launch the recovery environment

Error
CSetupManager::OnFinishLaunchChoiceAction(8149): Result = 0xC19001F4

The key point:

“User has requested to launch the recovery environment” is not the root cause. It is the action Windows Setup takes after the installation fails.

The flow is:

Install fails
    |
    v
Setup shows failure/recovery choice
    |
    v
Recovery environment selected
    |
    v
0xC19001F4 logged

So my previous suspicion about keyboard/recovery trigger is less likely. This log actually shows:

Next button clicked

meaning Setup UI moved forward normally.

The actual failure happened before this section.

Need the earlier error

Run this in WinPE command prompt:

cd C:\$WINDOWS.~BT\Sources\Panther

findstr /i "error failed failure rollback 0xc190" setupact.log > errors.txt

notepad errors.txt

Send the errors.txt content.

Also check these two files

1. Setup error log

notepad C:\$WINDOWS.~BT\Sources\Panther\setuperr.log

Look for the first error, not the last.

2. Installation phase

Find:

findstr /i "InstallImage ApplyImage ApplyOS" setupact.log

This tells us whether failure happened during:

applying Windows image
driver injection
boot configuration
OOBE phase

My current probability estimate from your previous history

Given:

Lenovo Xiaoxin
Windows 11 25H2 ISO
USB prepared on Mac
previous disk “offline/unrecognized type” issue

I would rank:

1. SSD partition metadata problem — 40%

Fix:

diskpart

list disk

select disk 0

clean

convert gpt

exit

Then install.

2. USB media / WIM issue — 35%

Check:

dir D:\sources

Need either:

install.wim

or:

install.swm
install2.swm
...

3. Driver/storage controller issue — 20%

Lenovo machines often use Intel VMD/RST.

BIOS check:

Storage Controller Mode

If enabled:

either load Intel RST driver during setup
or disable VMD and use AHCI

4. Actual recovery environment trigger — <5%

This screenshot basically rules that out.

The next useful screenshot is the first 50 lines around the first “Error” entry in setupact.log, not the ending. That will contain the real cause.
