# MiracleBoot v7.2.1 - Low Hanging Fruit Features Implementation
## Critical Enhancements to Prevent Windows Reinstallation

**Date Created:** $(Get-Date -Format 'yyyy-MM-dd HH:mm:ss')  
**Version:** 7.2.1  
**Status:** IMPLEMENTATION IN PROGRESS  

---

## Executive Summary

This document outlines the "low hanging fruit" features implemented to prevent forced Windows reinstallation by addressing two critical failure points:

1. **INACCESSIBLE_BOOT_DEVICE Errors** - Caused by missing storage/chipset drivers
2. **Network Connectivity Issues** - Preventing driver downloads and updates during recovery

These features transform MiracleBoot from a diagnostics tool into an **active recovery platform** capable of saving systems from catastrophic boot failures.

---

## Problem Statement

### Critical Issue #1: INACCESSIBLE_BOOT_DEVICE Error
**User Experience:** System fails to boot with 0xC0000225 or 0x0000007B error  
**Root Causes:**
- Missing SATA/NVMe/RAID controller drivers before/during Windows installation
- Incompatible chipset drivers
- BIOS SATA mode set to RAID/ACHI incompatible with drivers
- Corrupt BCD entries

**Current Impact:** Users forced to completely reinstall Windows (hours of recovery time)  
**Solution:** Detect and inject drivers BEFORE installation completes

### Critical Issue #2: Network Not Working During Recovery
**User Experience:** Cannot download drivers, cannot update, cannot access help during recovery  
**Root Causes:**
- DNS misconfiguration
- DHCP not assigning IP
- Corrupt TCP/IP stack (Winsock)
- Network driver issues
- Proxy/firewall settings

**Current Impact:** Recovery impossible if network access needed  
**Solution:** Provide Windows Troubleshooter equivalent CLI commands for network repair
