Question: Summary of the whole troubleshooting session so far.

Answer:

Setup: Lenovo Xiaoxin, previously Linux Mint, installing Windows 11 fresh. Disk 0 = 476GB UMIS NVMe (main SSD), Disk 1 = small ~14GB drive (ignore, unrelated).

What we fixed:

Original error — “partition unrecognized type / volume offline” — caused by leftover Linux Mint partition signatures (LVM/RAID) on Disk 0.
Fixed via diskpart: clean → convert gpt on Disk 0 (confirmed correct disk each time via detail disk).
Confirmed BIOS is UEFI-only (no Legacy/CSM toggle needed on this model).
Selected Disk 0 unallocated space correctly in Setup, clicked Next — partition selection itself is no longer the problem.

Current blocker: Install now fails during the “Installing Windows” progress phase with a generic “Windows 11 installation has failed” dialog. Log analysis (setupact.log / setuperr.log) shows:

Early errors (0x80070490, 0x80072EE7, 0x80070002) = harmless, just no internet in WinPE — ignore these.
Real fatal chain: CSetupManager::OnFinishLaunchChoiceAction(8149): Result = 0xC19001F4 — Setup receives a “launch recovery environment” request and self-aborts.
This happened twice in a row at the same point, ruling out accidental keypress as sole cause.

Not yet tried (next steps):

Re-download Windows 11 ISO fresh from Microsoft.
Re-flash a different USB stick with Rufus (GPT + UEFI target) — current USB media is now the top suspect.
Run the install completely hands-off (no keyboard/trackpad touch) from progress bar to OOBE.
If it fails identically a third time with fresh ISO + fresh USB + no touching → likely hardware issue (RAM or NVMe controller), not media/software — would need memory test (Windows Memory Diagnostic or MemTest86) and NVMe health check (nvme-cli or manufacturer tool) at that point.

Not needed: extending/manually creating partitions — Setup’s auto-partitioning of unallocated space is correct and not the issue.
