Run startup repair from Command Prompt

Best place to run it

Windows Recovery Environment Command Prompt is the right execution context for this page. Because this repair touches protected Windows state, a normal unelevated shell can return misleading access errors or partial results.

Fast repair workflow

1. Start from the exact symptom on this page: Windows fails before the desktop loads
2. Run the startup recovery line exactly as shown: X:\sources\recovery\StartRep.exe bootrec /scanos.
3. This workflow is tuned for this repair, so avoid mixing it with unrelated repair commands too early.
4. Re-check boot state with BCD or recovery info instead of repeating the same boot command blindly.
5. If startup still fails, move to partition, file-system, or recovery-media diagnostics instead of stacking more write operations.

Recovery command sequence

Use this sequence when you want the page command in a cleaner, step-by-step recovery block.

Verification commands after the repair

These follow-up commands help you check whether the repair actually changed the Windows state that matters, instead of assuming success from a single line.

What problem this command is trying to solve

This page targets systems that cannot boot normally and need repair actions from Windows Recovery Environment.

• Windows fails before the desktop loads.
• Automatic startup repair did not open on its own.
• You are already using the recovery Command Prompt.

How the command works

StartRep launches the built-in startup repair workflow, while bootrec /scanos checks whether Windows installations can still be discovered.

When it makes sense to run it

Use it when you are already in WinRE and want a structured repair step before deeper manual boot changes.

Before you run this command

• Open an elevated Command Prompt or PowerShell window before running X:\sources\recovery\StartRep.exe bootrec /scanos.
• Confirm that the symptom really matches this guide, especially if you are seeing signs such as: windows fails before the desktop loads.
• Write down the exact startup or recovery message before you change boot-related data.

What result to expect

After running X:\sources\recovery\StartRep.exe bootrec /scanos, compare the result against the symptom that brought you here. The most useful checkpoint is whether windows fails before the desktop loads becomes less frequent, changes form, or produces a clearer error message. A command page is stronger when it helps you verify a real change instead of just assuming the line must have worked.

How to verify that it worked

The best verification step after X:\sources\recovery\StartRep.exe bootrec /scanos is to repeat the action that previously triggered the problem. If automatic startup repair did not open on its own still appears in exactly the same way, the command probably was not the whole answer and you should move to the next targeted check instead of assuming the page is finished.

Why administrator rights matter here

This command changes startup, recovery, or boot configuration. Run it in an elevated shell so Windows can apply the repair instead of only returning an access or privilege error.

Before you run it

Paths can differ between recovery environments. If StartRep is unavailable, continue with the other WinRE repair tools instead.

When this is probably the wrong fix

This is not the right first fix for a simple slow boot caused by startup apps alone. Use it when Windows cannot start properly, recovery keeps appearing, or boot data itself looks damaged.

What to do if it does not help

If X:\sources\recovery\StartRep.exe bootrec /scanos does not improve windows fails before the desktop loads, move to the next repair step that matches the same symptom family instead of piling on random commands. The best follow-up depends on whether the failure is mainly about startup, recovery, or boot configuration.
