+# U-Claw Bootable USB (Linux)
+
+> **把任意电脑变成 AI 工作站 — 插上 U 盘，开机即用**
+>
+> **Turn any computer into an AI workstation — just boot from USB**
+
+## 独立性说明
+
+本目录 (`bootable/`) 在 u-claw 主仓库中保持**目录级别的独立**：
+
+- 不依赖仓库内 `portable/`、`u-claw-app/`、`website/` 中的任何文件
+- 所有脚本内部硬编码了 URL 和路径，完全自包含
+- 出问题只影响 `bootable/` 自身，不会波及其他模块
+- 同时维护了一份**独立仓库**：[u-claw-linux](https://github.com/dongsheng123132/u-claw-linux)，内容一致
+
+## 这是什么
+
+制作一个**可启动的 Linux AI U 盘**：
+
+- 插上任意电脑，从 U 盘启动，直接进入 Ubuntu 桌面
+- 一键安装 OpenClaw AI 助手，桌面图标双击即用
+- 内置持久化存储，安装的软件和数据重启后保留
+- **不需要目标电脑有任何操作系统**
+
+> 与便携版（`portable/`）的区别：便携版需要电脑已有 Windows/Mac 系统，可启动版连系统都不需要。
+
+## 技术方案
+
+```

+```
+
+**三个核心技术选型：**
+
+| 技术 | 为什么选它 |
+|------|-----------|
+| **Ventoy 1.0.99** | ISO 文件直接丢进去就能启动，不用烧录，可放多个系统 |
+| **Ubuntu 24.04 LTS** | 长期支持版，驱动兼容性最好，社区最大 |
+| **casper-rw 持久化** | 让 Live USB 也能保存数据，重启不丢失 |
+
+## 硬件要求
+
+| 项目 | 要求 |
+|------|------|
+| U 盘 | **32GB+**，强烈推荐 USB 3.0（蓝色接口） |
+| 制作环境 | Windows 10/11，PowerShell 5.1+ |
+| 目标电脑 | x86_64（Intel / AMD），任意品牌 |
+| 网络 | 首次安装 OpenClaw 时需要联网 |
+
+## 快速制作（4 步）
+
+在 Windows 上以**管理员身份**打开 PowerShell：
+
+```powershell
+cd path\to\u-claw\bootable
+
+# Step 1: 下载 Ventoy 并写入 U 盘（会格式化！）
+.\1-prepare-usb.ps1
+
+# Step 2: 下载 Ubuntu 24.04 ISO（~5.8GB，国内镜像）
+.\2-download-iso.ps1
+
+# Step 3: 创建持久化镜像（默认 20GB）
+.\3-create-persistence.ps1
+
+# Step 4: 拷贝所有文件到 U 盘
+.\4-copy-to-usb.ps1
+```
+
+## 每一步做了什么
+
+### Step 1: 写入 Ventoy 引导 (`1-prepare-usb.ps1`)
+
+- 列出所有 USB 设备，让你确认
+- 从 GitHub 下载 Ventoy 1.0.99
+- 启动 Ventoy2Disk.exe GUI
+- 你在 GUI 中选择 U 盘 → 点 Install
+- **注意：会格式化 U 盘，数据全丢！提前备份！**
+
+### Step 2: 下载 Ubuntu ISO (`2-download-iso.ps1`)
+
+- 从国内镜像下载 Ubuntu 24.04.2 桌面版（~5.8GB）
+- 镜像优先级：清华 → 阿里 → 中科大 → 官方
+- SHA256 校验确保文件完整
+- 有缓存，不会重复下载
+
+### Step 3: 创建持久化镜像 (`3-create-persistence.ps1`)
+
+这是整个方案**最关键**的一步：
+
+- 检测是否安装了 WSL（Windows 子系统 Linux）
+- **有 WSL** → 用 `mkfs.ext4` 直接创建格式化好的 ext4 镜像
+- **没 WSL** → 创建稀疏文件，首次进 Linux 后需手动格式化
+- 卷标必须是 `casper-rw`（Ubuntu 持久化的约定）
+- 默认 20GB，可选 1-28GB
+
+### Step 4: 拷贝到 U 盘 (`4-copy-to-usb.ps1`)
+
+- 自动识别 Ventoy U 盘（通过卷标）
+- 检查剩余空间
+- 拷贝 4 样东西：ISO、persistence.dat、ventoy.json、安装脚本
+
+## 使用方法
+
+### 首次使用
+
+1. 将 U 盘插入目标电脑
+2. 开机按启动键：
+
+| 品牌 | 启动键 |
+|------|--------|
+| Dell 戴尔 | F12 |
+| Lenovo 联想 | F12 |
+| HP 惠普 | F9 |
+| ASUS 华硕 | F2 或 DEL |
+| Acer 宏碁 | F12 |
+| MSI 微星 | F11 |
+| Huawei 华为 | F12 |
+| Xiaomi 小米 | F12 |
+
+3. 启动菜单选择 USB 设备
+4. Ventoy 菜单 → 选择 Ubuntu
+5. 等待 Ubuntu 桌面加载
+6. 连接 Wi-Fi
+7. 打开终端（`Ctrl+Alt+T` 或右键桌面 → Open Terminal）
+8. 运行安装命令：
+
+```bash
+sudo bash /media/*/Ventoy/u-claw-linux/setup-openclaw.sh
+```
+
+9. 桌面出现 **"U-Claw AI Assistant"** 图标
+10. 双击图标 → 浏览器打开 → 配置 AI 模型
+
+### 日常使用
+
+1. 插入 U 盘 → 开机选 USB → Ubuntu 桌面
+2. 双击桌面图标
+3. 所有数据自动保留
+
+## 安装脚本详解 (`setup-openclaw.sh`)
+
+9 个步骤，完全自包含：
+
+| 步骤 | 操作 | 说明 |
+|------|------|------|
+| 1 | 检查 root 权限 | 必须 `sudo` 运行 |
+| 2 | 安装系统依赖 | `curl`, `xdg-utils` |
+| 3 | 创建目录 | `/opt/u-claw/{runtime,core,data}` |
+| 4 | 下载 Node.js v22 | 国内镜像优先，官方回退 |
+| 5 | 创建 package.json | — |
+| 6 | 安装 OpenClaw + QQ 插件 | npm 国内镜像 |
+| 7 | 写默认配置 | gateway + token |
+| 8 | 安装启动脚本 | → `/opt/u-claw/` |
+| 9 | 创建桌面快捷方式 | 可选开机自启 |
+
+## 核心配置文件
+
+### `ventoy/ventoy.json`
+
+```json
+{
+  "persistence": [
+    {
+      "image": "/ubuntu-24.04.2-desktop-amd64.iso",
+      "backend": "/persistence.dat",
+      "autosel": 1
+    }
+  ]
+}
+```
+
+告诉 Ventoy：启动 Ubuntu ISO 时自动加载 `persistence.dat`。`autosel: 1` = 不弹确认框。
+
+### Linux 端环境变量
+
+| 变量 | 值 |
+|------|-----|
+| `OPENCLAW_HOME` | `/opt/u-claw/data/.openclaw` |
+| `OPENCLAW_STATE_DIR` | `/opt/u-claw/data/.openclaw` |
+| `OPENCLAW_CONFIG_PATH` | `/opt/u-claw/data/.openclaw/openclaw.json` |

+```
+
+## 实践经验与注意事项
+
+### 制作阶段
+
+1. **U 盘选择很重要**
+   - 必须 32GB+（ISO 5.8GB + 持久化 20GB + 系统开销）
+   - 强烈建议 USB 3.0，否则启动和运行都会很慢
+   - 推荐品牌：闪迪、金士顿、三星（杂牌盘容易出问题）
+   - 避免使用 USB Hub，直接插主板接口
+
+2. **Step 1 会清空 U 盘**
+   - Ventoy 安装会格式化整个 U 盘，**务必提前备份**
+   - 脚本会列出所有 USB 设备让你确认，看清楚再操作
+
+3. **Step 3 持久化镜像**
+   - 有 WSL → 自动创建 ext4 镜像（最省事）
+   - 没 WSL → 创建空文件，首次进 Linux 后需手动格式化：
+     ```bash
+     sudo mkfs.ext4 -F -L casper-rw /media/*/Ventoy/persistence.dat
+     ```
+     格式化后**必须重启**才能生效
+   - 大小建议：32GB U 盘选 20GB，64GB U 盘可选 40GB+
+
+4. **ISO 下载失败**
+   - 脚本默认走清华/阿里/中科大国内镜像，无需翻墙
+   - 如果全部失败，手动下载 Ubuntu ISO 放到 `.download-cache/` 目录即可
+
+### 启动阶段
+
+5. **Secure Boot 问题**
+   - 部分电脑需要关闭 Secure Boot 才能从 U 盘启动
+   - 进 BIOS → Security → Secure Boot → Disabled
+   - 不同品牌进 BIOS 的方式不同（通常 DEL 或 F2）
+
+6. **找不到 USB 启动项**
+   - 换个 USB 口试试
+   - 有些电脑默认禁用了 USB 启动，需要在 BIOS 中开启
+   - Legacy/CSM 模式和 UEFI 模式都试试
+
+7. **Ubuntu 桌面加载慢**
+   - 正常现象，Live USB 从 U 盘读取比硬盘慢
+   - USB 3.0 U 盘 + USB 3.0 接口会快很多
+   - 首次加载约 1-3 分钟
+
+### 使用阶段
+
+8. **Wi-Fi 连接**
+   - Ubuntu 24.04 支持大多数 Wi-Fi 芯片
+   - 不行的话用手机 USB 共享网络，或 USB 无线网卡
+
+9. **OpenClaw 安装需要网络**
+   - 国内镜像优先，无需翻墙
+   - 安装过程约 1-2 分钟
+
+10. **端口冲突**
+    - OpenClaw 使用端口 18789-18799
+    - 提示端口占用 → 关闭终端窗口再重新打开
+
+11. **数据位置**
+    - 安装目录：`/opt/u-claw/`
+    - 配置文件：`/opt/u-claw/data/.openclaw/openclaw.json`
+    - 所有数据保存在持久化镜像中，重启不丢
+
+12. **性能预期**
+    - U 盘运行比硬盘慢，这是物理限制
+    - AI 推理在云端，本地只跑网关，对话速度不受影响
+
+## 常见故障排查
+
+| 问题 | 解决方案 |
+|------|---------|
+| 无法从 U 盘启动 | BIOS 关闭 Secure Boot，开启 USB Boot |
+| Ventoy 菜单无 Ubuntu | ISO 文件是否在 Ventoy 数据分区根目录 |
+| 持久化不生效（重启丢数据） | persistence.dat 是否已格式化为 ext4，卷标是否为 `casper-rw` |
+| OpenClaw 安装失败 | 检查网络，确认能访问 npmmirror.com |
+| 浏览器打不开 | 手动打开浏览器访问 `http://localhost:18789` |
+| 屏幕分辨率不对 | Settings → Displays → Resolution |
+
+## 技术说明
+
+- **Ventoy**: 开源引导管理器，ISO/WIM/VHD 直接启动，更新 ISO 不用重新格式化
+- **Persistence**: Ventoy persistence 插件 + `casper-rw` 标签 ext4 镜像
+- **Node.js**: v22.14.0 LTS，npmmirror.com（国内）或 nodejs.org
+- **OpenClaw**: npm latest，安装到 `/opt/u-claw/`
+- **完全独立**: 不引用仓库内 `portable/`、`u-claw-app/`、`website/` 的任何文件
