# Fix: CD-ROM Not Shown in Boot Order

## Problem
CD-ROM option doesn't appear in Boot Order because the CD/DVD drive isn't attached yet.

## Solution: Attach ISO First, Then Set Boot Order

### Step-by-Step (For Each VM)

#### Step 1: Attach CD/DVD Drive with ISO

1. **Open Proxmox Web UI:** https://192.168.1.206:8006
2. **Click on VM** (e.g., "cloudflare-tunnel" or VM 100)
3. **Go to "Hardware" tab**
4. **Click "Add" button** (top right, blue button)
5. **Select "CD/DVD Drive"** from the dropdown menu
6. **In the dialog:**
   - **Storage:** Select `local` from dropdown
   - **ISO image:** Click the dropdown
   - **Select:** `ubuntu-24.04.3-live-server-amd64.iso`
   - **Click "Add"** button at bottom
7. **Verify:** You should now see "CD/DVD Drive (ide2)" in the Hardware list

#### Step 2: Set Boot Order (Now CD-ROM Will Appear)

1. **Go to "Options" tab**
2. **Find "Boot Order"** in the list
3. **Click "Edit"** (or double-click)
4. **Now you'll see CD-ROM option!**
   - Drag "CD-ROM" to the top (or select it as first)
   - Or use the up/down arrows to move it first
5. **Click "OK"**

#### Step 3: Start VM

1. **Click "Start" button** (top right)
2. **Click "Console" tab**
3. **Ubuntu installer should boot!**

### Important Notes

- **If CD-ROM still doesn't appear:**
  - Verify CD/DVD drive shows in Hardware tab
  - Try refreshing the page
  - Try removing and re-adding the CD/DVD drive

### For All 4 VMs

Repeat the above steps for:
- VM 100: cloudflare-tunnel
