## WORKFLOW EXAMPLES

### Example 1: Simple Boot Repair with Drive Selection

```powershell
# User clicks "Rebuild BCD" button
$drive = Select-OperationDrive `
    -OperationName "Rebuild BCD" `
    -DefaultDrive (Get-DefaultDrive) `
    -AllowOverride (Get-AllowDriveOverride) `
    -SuppressWarnings (Get-SuppressWarnings)

if ($drive) {
    $msg = Format-DriveStatusMessage -Message "Starting BCD rebuild..." `
        -DriveLetter $drive -OperationType "Boot Repair"
    
    Write-Host $msg  # Shows: [14:35:22 | Drive: C: | Boot Repair] Starting BCD rebuild...
    
    Rebuild-BCD -TargetDrive $drive
}
```

### Example 2: Settings Management Flow

```powershell
# User clicks Settings gear icon
Show-SettingsWindow

# User interface allows:
#  1. Set default drive (C, D, E, etc.)
#  2. Toggle warning on default drive usage
#  3. Allow/disallow drive override
#  4. Enable verbose logging
#  5. Auto-backup before repairs
#  6. Confirm destructive operations
#  7. Reset to defaults
```

### Example 3: Complete Operation with All Features

```powershell
Invoke-DriveSelectorRepairOperation `
    -OperationName "Fix Boot Sector" `
    -OperationScript { 
        param($DriveLetter)
        Run-BootFix -Drive $DriveLetter
    } `
    -OutputBox $TextBoxOutput

# This automatically handles:
#  - Drive selection
#  - Warning dialogs
#  - Default drive usage
#  - Auto-backup if enabled
#  - Confirmation if destructive
#  - Status messages with drive context
#  - Logging with verbose mode
```

---

## INTEGRATION STEPS

### Step 1: Load Modules (in Start-GUI function)

```powershell
# Add to beginning of Start-GUI in WinRepairGUI.ps1
. (Join-Path $PSScriptRoot "DriveSelectionManager.ps1")
. (Join-Path $PSScriptRoot "GlobalSettingsManager.ps1")
```

### Step 2: Add Settings Button to Toolbar

```xml
<!-- Add to XAML toolbar in WinRepairGUI.ps1 -->
<Separator Margin="10,0"/>
<Button Content="⚙️ Settings" Name="BtnSettings" Width="100" Height="25" 
    Margin="2" ToolTip="Global Settings and Preferences"/>
```

### Step 3: Create Settings Button Handler

```powershell
# Add event handler in WinRepairGUI.ps1
if ($null -ne $window.FindName("BtnSettings")) {
    $window.FindName("BtnSettings").Add_Click({
        Show-SettingsWindow
    })
}
```

### Step 4: Update Each Repair Function Button

```powershell
# Example: Fix Boot button
$btnFixBoot.Add_Click({
    $drive = Select-OperationDrive `
        -OperationName "Fix Boot Sector" `
        -DefaultDrive (Get-DefaultDrive) `
        -AllowOverride (Get-AllowDriveOverride) `
        -SuppressWarnings (Get-SuppressWarnings)
    
    if ($drive) {
        $msg = Format-DriveStatusMessage -Message "Starting fix..." `
            -DriveLetter $drive -OperationType "Boot Repair"
        $FixerOutput.AppendText("$msg`n")
        
        # Run repair with drive parameter
        $result = Invoke-BootFix -Drive $drive
        $FixerOutput.AppendText($result)
        $FixerOutput.ScrollToEnd()
    }
})
```

### Step 5: Update Status Messages Throughout

```powershell
# Before:
$statusBox.Text = "Analyzing system..."

# After:
$statusMsg = Format-DriveStatusMessage `
    -Message "Analyzing system..." `
    -DriveLetter $selectedDrive `
    -OperationType "Diagnostics"
$statusBox.Text = $statusMsg
```

## CONFIGURATION OPTIONS

### Via GUI Settings Window
1. **Default Drive**: Choose C, D, E, etc. or "Prompt Always"
2. **Warning Preferences**: Enable/disable default drive warnings
3. **Drive Override**: Allow switching drives mid-operation
4. **Logging**: Enable verbose mode with drive details
5. **Auto-Backup**: Automatically backup before repairs
6. **Confirmation**: Require confirmation on destructive operations
7. **Remember Drive**: Remember last used drive for session

### Via PowerShell (Programmatic)
```powershell
# Set default to C: drive
Set-DefaultDrive "C"

# Disable warnings for experienced users
Set-SuppressWarnings $true

# Allow drive override
Set-AllowDriveOverride $true

# Enable verbose logging
Set-VerboseLogging $true

# Auto-backup BCD before repairs
Set-AutoBackupBeforeRepair $true

# Get current settings summary
Get-SettingsSummary
```

### Environment Variables (Advanced)
```powershell
# Override default drive (environment variable takes precedence)
$env:MIRACLEBOOT_DEFAULT_DRIVE = "D"

# Force verbose mode
$env:MIRACLEBOOT_VERBOSE = "true"
```

---

## TROUBLESHOOTING

### Problem: Settings File Not Saving
**Solution:**
- Check folder exists: `mkdir %APPDATA%\MiracleBoot\`
- Check write permissions on folder
- Ensure disk has free space
- Run as Administrator if needed

### Problem: Drive Selection Dialog Not Showing
**Solution:**
- Verify WPF assemblies are installed
- Check PowerShell execution policy
- Enable fallback to console selection
- Check for WPF errors in PowerShell console

### Problem: Default Drive Not Persisting
**Solution:**
- Verify Save-Settings is called after Set-Setting
- Check if AppData folder is accessible
- Ensure settings XML file is created: `dir %APPDATA%\MiracleBoot\`
- Try exporting and re-importing settings

### Problem: Status Messages Not Including Drive
**Solution:**
- Verify Format-DriveStatusMessage is called
- Check drive letter format (single letter, no colon)
- Verify OperationType parameter is provided
- Check for module loading errors

### Problem: Drives Not Detected
**Solution:**
- Run as Administrator
- Check drive letter assignment: `wmic logicaldisk get name`
- Verify Get-Volume permissions
- Check for USB drive connection
- Look for offline/hidden drives

---

## PERFORMANCE IMPACT

- **Module Loading**: ~50ms per module
- **Settings Save**: ~10ms (XML write)
- **Settings Load**: ~5ms (XML read)
- **Drive Selection Dialog**: ~100ms (display)
- **Status Formatting**: <1ms per message
- **Total Overhead**: Negligible (<200ms for complete operation)

---

## SECURITY CONSIDERATIONS

1. **Settings File**: Stored in user AppData (user-readable)
   - Contains no passwords or sensitive data
   - User can export/backup manually
   - Access restricted to user account

2. **Drive Selection**: Only accesses local drives
   - No network access required
   - No remote calls made
   - All operations local and offline-safe

3. **Settings Validation**: XML schema validation
   - Detects corrupted settings
   - Falls back to defaults on error
   - No SQL injection or code execution risk

4. **Status Messages**: No sensitive information
   - Only includes drive letters and operation types
   - No file paths or user data
   - Safe for logging to files

---

## FUTURE ENHANCEMENTS

1. **Multi-Drive Operations**: Queue repairs for multiple drives
2. **Drive Profiles**: Save operation templates per drive
3. **Health Dashboard**: Real-time drive monitoring
4. **Scheduled Tasks**: Schedule repairs for specific drives
5. **Cloud Sync**: Sync settings across machines
6. **Drive History**: Log all operations per drive
7. **Auto-Detect**: Intelligently select best repair method per drive
8. **Metrics**: Track repair success rates per drive
