Manual Fix: Remove Floppy from Boot Order

Problem

VM keeps booting from floppy even though floppy drive isn't in hardware. This is because floppy is in the default BIOS boot order.

Solution: Set Boot Order via Proxmox Web UI

Step-by-Step Instructions

  1. Access Proxmox Web UI

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

    A. Stop the VM (if running)

    • Click VM → Stop button
    • Wait for it to stop

    B. Go to Options Tab

    • Click on the VM
    • Click Options tab (left sidebar)

    C. Edit Boot Order

    • Find "Boot Order" in the list
    • Click on it (or double-click)
    • Click "Edit" button

    D. Configure Boot Order

    • Look for a text field or dropdown
    • If text field: Type: order=ide2;scsi0
      • ide2 = CD/DVD drive (ISO)
      • scsi0 = Hard disk
      • ; separates devices (first = highest priority)
    • If dropdown:
      • Remove "Floppy" from boot order
      • Set "CD-ROM" as first
      • Set "Hard Disk" as second
    • Click OK

    E. Verify Hardware

    • Go to Hardware tab
    • Verify CD/DVD Drive (ide2) exists
    • Verify it shows: ubuntu-24.04.3-live-server-amd64.iso
    • If you see Floppy Drive, click it → Remove

    F. Start VM

    • Click Start button
    • Open Console tab
    • Should boot from CD-ROM now!

Alternative: Use BIOS Boot Menu

If Web UI boot order doesn't work:

  1. Start VM
  2. Open Console
  3. Press F2 or Delete immediately when VM starts
  4. Enter BIOS/UEFI settings
  5. Navigate to "Boot" menu
  6. Find "Boot Priority" or "Boot Order"
  7. Move CD/DVD to top (use +/- or arrow keys)
  8. Move Floppy to bottom or disable it
  9. Save and Exit (usually F10)

Quick Test

After setting boot order:

  • Start VM → Console
  • Should see Ubuntu installer boot screen
  • If still shows floppy error, use BIOS method above

Boot Order Format

In Proxmox, boot order can be set as:

  • order=ide2;scsi0 = CD-ROM first, then disk
  • order=scsi0;ide2 = Disk first, then CD-ROM
  • order=ide2 = CD-ROM only

We want: order=ide2;scsi0

Troubleshooting

Boot order field is read-only:

  • Stop the VM first
  • Some Proxmox versions require VM to be stopped

CD-ROM still not booting:

  • Verify ISO is attached in Hardware tab
  • Check boot order text field has ide2 first
  • Try BIOS boot menu method

Floppy still appears:

  • Remove floppy drive from Hardware tab (if exists)
  • Set boot order explicitly to skip floppy
  • Use BIOS to disable floppy boot
