Since System Restore and network troubleshooting have already failed, use Windows Recovery Environment to uninstall the latest update, then run offline disk and system-file repairs if Windows still will not start.
The SrtTrail.txt path identifies Startup Repair’s diagnostic log; it is not a file that should be deleted. The “couldn’t connect to the network” message concerns networking inside the recovery environment and does not, by itself, mean that your modem or normal Wi-Fi caused the startup failure. Windows RE uses networking only for recovery operations that require it.^1^
1. Uninstall the latest Windows update
From the screen currently displayed:
- Select Enter or See other recovery options.
- Select Troubleshoot > Advanced options > Uninstall Updates.
- Select Uninstall latest quality update.
- Restart the computer.
If that does not work and Uninstall latest feature update is available, return to the same menu and try that option. Microsoft recommends uninstalling updates from WinRE when a PC will not start, particularly when the problem began recently.^2^
If BitLocker requests a recovery key, it must be entered before some WinRE tools can access Windows.
2. Run offline disk and system-file repairs
If uninstalling the update does not restore startup:
- Open Troubleshoot > Advanced options > Command Prompt.
- Identify the actual Windows drive letter:
bcdedit
Under Windows Boot Loader, find osdevice. In WinRE, Windows may be D: even if it is normally C:. The path shown in your error suggests D:, but verify it rather than assuming.
- Replace
D: below if osdevice shows another letter, then run each command separately:
chkdsk /f D:
sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows
dism /image:D:\ /cleanup-image /restorehealth
These commands check the Windows volume, repair protected system files offline, and repair the offline Windows image. If DISM repairs anything, run the sfc command again, then close Command Prompt and restart.^3^
If chkdsk reports failures it cannot repair, the storage device may need further hardware diagnostics before reinstalling Windows.
3. Try Safe Mode
If repairs complete but normal startup still fails:
- Select Troubleshoot > Advanced options > Startup Settings > Restart.
- After restart, select Safe Mode.
- If Windows opens, remove any driver, application, or update installed immediately before the startup problem began.
Safe Mode loads only essential services and drivers, which helps isolate startup problems.^4^
4. Reset or reinstall only if repairs fail
First try Troubleshoot > Reset this PC > Keep my files. This reinstalls Windows while retaining personal files, but installed applications and some settings can be removed.^2^
If Reset fails:
- On another working PC, create Windows installation media using a blank USB drive of at least 8 GB. Creating the media erases the USB.^5^
- Boot the affected computer from that USB.
- At Windows Setup, select Next > Repair your computer to access WinRE from the USB.
- Back up important files before choosing a clean installation.
A clean installation is the final fallback because it removes personal files, applications, settings, and manufacturer customizations.^6^
