## Step 3: Create a Bootable Debian USB with Rufus

Now that you've launched **Rufus** and selected the Debian ISO, here’s what to do next:

### 🧭 1. **Device**

* Make sure the correct USB drive is selected under **Device** (e.g., `ggUSB (G:)`).
* ⚠️ **Warning:** All data on this USB drive will be erased.

### 📦 2. **Boot Selection**

* The Debian ISO should already be loaded (e.g., `debian-12.10.0-amd64-netinst.iso`).
* If not, click **Select** and browse to the ISO you downloaded earlier.

### ⚙️ 3. **Partition Scheme & Target System**

* **Partition scheme:** `MBR`
* **Target system:** `BIOS or UEFI`

> ✅ This setup works on most systems. If you're only targeting newer UEFI systems, you can also choose `GPT` + `UEFI (non-CSM)`.

### 💾 4. **Format Options**

* **Volume label:** Change it to something like `Debian` (optional but helpful).
* **File system:** `FAT32 (Default)`
* **Cluster size:** `4096 bytes (Default)`

No need to touch the "Advanced format options" unless you know what you're doing.

### 🔥 5. **Start the Process**

* Click the **START** button.

### 🧪 6. **ISOHybrid Mode Prompt**

* Rufus may ask how to write the image:

* Choose **Write in ISO Image mode (Recommended)** and click **OK**.

### 🧼 7. **Confirmation Warning**

* You’ll see a final warning that all data on the USB drive will be destroyed.
* Confirm and proceed.
