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

• You must attach the ISO in Hardware tab BEFORE setting boot order
• 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
• VM 101: k3s-master
• VM 102: git-server
