Fix "No Bootable Disk" Error

Problem

VMs are showing "No bootable disk" error when starting.

Solution

Option 1: Fix via Proxmox Web UI (Recommended)

1. Access Proxmox: https://192.168.1.206:8006

2. For each VM (100, 101, 102, 103):

   a. Add CD/DVD Drive (if missing):

   • Click VM → Hardware tab
   • Click "Add" → "CD/DVD Drive"
   • Storage: local
   • ISO image: ubuntu-24.04.3-live-server-amd64.iso
   • Click "Add"

   b. Set Boot Order:

   • Click VM → Options tab
   • Boot Order: Select "CD-ROM" first
   • Click "OK"

   c. Verify Network:

   • Click VM → Hardware tab
   • Ensure Network Device exists
   • If missing: Add → Network Device → Bridge: vmbr0

3. Start VM:

   • Click VM → Start
   • Open Console
   • Ubuntu installer should boot

Option 2: Automated Fix (Attempted)

The script scripts/fix-boot-config.sh has been run to attempt fixing via API.

If it didn't work, use Option 1 (Web UI) as the API has format limitations.

Verification

After fixing, verify:

1. VM boots from ISO (Ubuntu installer appears)
2. Network works (if Ubuntu installer shows network)
3. Installation can proceed

Troubleshooting

If ISO still doesn't boot:

• Verify ISO exists in Proxmox storage: Storage → local → ISO images
• Check VM has CD/DVD drive in Hardware tab
• Verify boot order in Options tab
• Try detaching and re-attaching ISO

If "No bootable disk" persists:

• Check if disk (scsi0) exists in Hardware tab
• Verify boot order includes both CD-ROM and disk
• Try resetting VM (Stop → Start)

Quick Fix Checklist

For each VM:

• CD/DVD drive exists in Hardware tab
• ISO is attached (ubuntu-24.04.3-live-server-amd64.iso)
• Boot order is set to CD-ROM first (Options tab)
• Network device exists (Hardware tab)
• VM is started
• Console shows Ubuntu installer
