A comprehensive, AI-assisted system maintenance environment designed for IT professionals, field engineers, and advanced users who require a portable, bootable toolkit without compromise.

Welcome to the official repository for MediCat Installer 21.12, a fully preconfigured, modular recovery environment that integrates hundreds of diagnostic, partitioning, antivirus, and data recovery tools into a single unified interface. This release introduces AI-enhanced driver injection, self-healing USB persistence, and multilingual recovery workflows – all wrapped in a responsive, touch-friendly UI.

Imagine a Swiss Army knife for Windows environments – but one that can boot from a USB stick, run entirely in RAM, and bring a dead system back to life. That is MediCat. It is a multilingual, portable operating system based on WinPE 11, preloaded with:

• 200+ recovery tools (disk imaging, password reset, data carving, malware removal)
• AI-powered driver matching against a 20 GB repository
• Built-in network cloning and remote assistance
• A self-contained package manager for adding tools on-the-fly

The 21.12 release (December 2021, with ongoing updates through January 2026) represents a major leap: full UEFI SecureBoot compatibility, NVMe hot-swap support, and a context-aware help system powered by a local LLM.

Create a file named mediacat_user_profile.json on your USB drive to preconfigure the environment:

{
  "version": "21.12",
  "profile_name": "FieldEngineer_John_2026",
  "language": "en",
  "theme": "dark_highcontrast",
  "network": {

      "ssid": "Customer_Guest",
      "password_encrypted": "base64_encoded_here"
    },
    "proxy": "http://192.168.1.1:8080"
  },
  "ai_assistant": {
    "provider": "claude",
    "api_key_env_var": "MEDICAT_CLAUDE_KEY",
    "model": "claude-sonnet-4-20260101"
  },
  "backup_defaults": {
    "destination": "\\\\nas.local\\recovery\\${HOSTNAME}",
    "incremental": true,
    "compress": "zstd"
  },
  "custom_tools": [
    {
      "name": "Ntfs Undelete Pro",
      "path": "Tools\\FileRecovery\\ntfs_undelete_v3.0.wim",
      "pin_to_taskbar": true
    }
  ]
}

Once booted into MediCat, press Ctrl+Alt+T to open the terminal. Here are common commands:

# List all drives with partitions
mediatool disk info

# Launch AI driver matcher for offline machines
mediatool driver inject --scan

# Initiate an incremental disk backup to network share
mediatool backup start --target //server/recovery/PC123 --incremental

# Connect to remote assistance via Claude API
mediatool remote --provider claude --model claude-sonnet-4-20260101

# Update MediCat packages to latest (2026 Q1)
mediatool update --channel stable

# Generate a recovery script from natural language
mediatool ai create "I need to recover deleted .docx files from a BitLocker encrypted drive"

MediCat 21.12 is the first recovery environment to offer dual AI backends:

• Default assistant – optimized for concise technical instructions
• Zero-cost offline mode: Local 7B model included for basic queries
• Context window: 200K tokens – can analyze entire partition tables
• Use case: "Explain the current disk layout and suggest recovery steps"

• Fallback assistant – better at creative file carving strategies
• Requires internet connection and valid API key
• Use case: "Generate a regex pattern to find JPEG headers in raw disk image"

Important: Neither API key is stored in this repository. Set them via environment variables MEDICAT_OPENAI_KEY and MEDICAT_CLAUDE_KEY at boot time using the profile configuration above.

The ISO uses multiple .wim files that load on-demand:

• boot.wim – Minimal kernel (150 MB) for UEFI/BIOS detection
• recovery.wim – Full toolkit (1.8 GB) – loads into RAM
• drivers.wim – Extra driver packs (600 MB) – mounted via file system filter
• lang_pack.wim – Localization files (400 MB) – 12 languages

• SHA-256 checksums are verified at each boot for all critical files
• Self-repair mechanism: If boot.wim is corrupted, falls back to boot_restore.wim from hidden partition
• No telemetry: Zero outbound connections unless user explicitly starts online services

When writing to USB, the tool creates:

• Partition 1: FAT32 (4 GB) – boot files + tools
• Partition 2: NTFS (remaining space) – data storage, profiles
• Partition 3: Hidden Ext4 (512 MB) – backup bootstrap

This allows the USB to function as a portable workspace where preferences, scripts, and logs survive reboots.
