# Boot Diagnosis & Repair Implementation Summary

## Overview
The Boot Diagnosis & Repair feature has been implemented across all three interface modes (GUI, TUI/CMD, and CMD-only) with support for three operation modes.

## Operation Modes

### 1. DIAGNOSIS ONLY
- **Purpose**: Finds what's broken without applying any fixes
- **Use Case**: When you want to understand the problem before deciding on a repair strategy
- **Output**: Detailed report of all detected issues

### 2. DIAGNOSIS + FIX
- **Purpose**: Automatically diagnoses and fixes issues
- **Use Case**: When you want a fully automated repair process
- **Output**: Diagnosis report + repair results

### 3. DIAGNOSIS THEN ASK
- **Purpose**: Diagnoses first, then asks the user if they want to apply fixes
- **Use Case**: When you want to review issues before committing to repairs
- **Output**: Diagnosis report + user prompt for repair confirmation

## Implementation by Interface

### GUI (PowerShell/WPF)
**File**: `Helper/WinRepairGUI.ps1`
**Button**: "Boot Diagnosis & Repair" (Boot Fixer tab)
**Features**:
- Prompts user for operation mode (Yes/No/Cancel dialog)
- Prompts user for verbose mode (Yes/No dialog)
- Lists all detected Windows installations for selection
- Creates unique log file (`%TEMP%\BootDiagnosis_YYYYMMDD_HHMMSS.log`)
- Opens log file in Notepad for real-time updates (if verbose mode)
- Displays progress in GUI textbox with phase-by-phase updates
- Shows final report with recommendations

**8 Diagnosis Phases**:
1. UEFI/GPT Integrity Check
2. BCD File & Integrity
3. BCD Entries Validation
4. WinRE Access
5. Driver Matching
6. Windows Kernel
7. Boot Log Analysis
8. Event Log Analysis

### TUI (PowerShell Console)
**File**: `Helper/WinRepairTUI.ps1`
**Menu Option**: "A) Advanced Diagnostics" → "1) Boot Diagnosis & Repair"
**Features**:
- Prompts user for operation mode (1/2/3 menu)
- Prompts user for verbose mode (Y/N)
- Lists all detected Windows installations for selection
- Creates unique log file (`%TEMP%\BootDiagnosis_YYYYMMDD_HHMMSS.log`)
- Opens log file in Notepad for real-time updates (if verbose mode)
- Displays real-time phase-by-phase progress in console
- Shows final report with recommendations

**8 Diagnosis Phases**: Same as GUI

### CMD (Batch Script)
**File**: `Helper/WinRepairCore.cmd`
**Menu Option**: "6) Boot Diagnosis & Repair"
**Features**:
- **If PowerShell is available**:
  - Prompts user for operation mode (1/2/3 menu)
  - Prompts user for verbose mode (Y/N)
  - Calls PowerShell `Start-BootDiagnosisAndRepair` function
  - Full 8-phase diagnosis with all features
- **If PowerShell is NOT available**:
  - Falls back to simplified CMD-only diagnosis
  - 4 simplified phases:
    1. Critical boot files check (ntoskrnl.exe, winload.efi/winload.exe)
    2. BCD file check (mounts EFI partition, verifies BCD exists and is readable)
    3. Windows directory structure check (SYSTEM registry hive)
    4. Boot failure logs check (memory dumps, CBS logs)
  - Provides summary with issue count and recommendations

## Function: Start-BootDiagnosisAndRepair

**Location**: `Helper/WinRepairCore.ps1`
**Parameters**:
- `-Drive` (string): Target Windows drive letter (default: "C")
- `-Mode` (ValidateSet): "DiagnosisOnly", "DiagnosisAndFix", "DiagnosisThenAsk" (default: "DiagnosisOnly")
- `-Verbose` (switch): Enable detailed command logging
- `-ProgressCallback` (scriptblock): Callback for progress updates

## Verbose Mode Features

When verbose mode is enabled:
- Detailed command logging to file
- Real-time progress updates with elapsed time
- Command-by-command output
- Phase descriptions and checkpoint messages
- Log file automatically opened in Notepad for live updates

**Estimated Time**:
- Regular mode: 2-5 minutes
- Verbose mode: 5-10 minutes

## Integration with Other Features

### Drive Selection
All modes use `Get-WindowsInstallations` to:
- Scan all drives for Windows installations
- Check for `\Windows\System32\ntoskrnl.exe` and `\Windows\System32\config\SYSTEM`
- Display drive letter, volume label, OS version, size, free space, health status, boot type
- Highlight current OS installation
- Allow user to select target installation

### Repair Integration
When mode is "DiagnosisAndFix" or user confirms after "DiagnosisThenAsk":
- Calls `Start-AutomatedBootRepair` for automated fixes
- Creates restore point before repairs
- Provides detailed repair report
- Re-runs diagnosis after repairs to verify fixes

## Testing Status

✅ **GUI Mode**: Implemented and tested
✅ **TUI Mode**: Implemented and tested
✅ **CMD Mode (PowerShell)**: Implemented and tested
✅ **CMD Mode (No PowerShell)**: Implemented with simplified diagnosis

## Files Modified

1. `Helper/WinRepairCore.ps1` - Added `Start-BootDiagnosisAndRepair` function
2. `Helper/WinRepairGUI.ps1` - Added `BtnFullBootDiagnosis` handler
3. `Helper/WinRepairTUI.ps1` - Added boot diagnosis menu option
4. `Helper/WinRepairCore.cmd` - Added `:BootDiagnosis` function

## Notes

- All modes support the same three operation modes (Diagnosis Only, Diagnosis+Fix, Diagnosis Then Ask)
- CMD mode falls back to simplified diagnosis only if PowerShell is completely unavailable
- Verbose mode provides transparency for long-running operations
- Drive selection ensures users can choose the correct Windows installation
- Log files are automatically created and opened for user review
