### **Preparing Your USB Drive**

Before installing the EFI Bootloader, you need to format your USB drive properly.

#### **Step 1: Format the USB Drive**

1. **Plug** your USB drive into an available USB port on your computer.
2. **Open File Explorer** by pressing **Win + E** and locate your USB drive under **"This PC"** or **"My Computer."**
3. **Right-click** on your USB drive and select **"Format."**

#### **Step 2: Configure Format Settings**

1. In the **Format window**, set the following options:
   * **File System**: Select **FAT32** (If unavailable for drives larger than 32GB, use tools like Rufus or GUIFormat).
   * **Volume Label**: Optionally, name your drive.
   * **Quick Format**: Check this box for a faster format, or leave it unchecked for a thorough format.
2. **Click "Start"** to begin formatting. A warning will appear stating that all data will be erased. Ensure you’ve backed up important files.
3. Wait a few moments for the format to complete. A confirmation message will appear once it’s done.

> **Important Note:** Formatting will erase all data. Backup important files before proceeding.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://chams-services.gitbook.io/chams-services-loader/rust/rust-calamari-external.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
