Overview
Why “No device with valid ISO found” in Proxmox?
The error “No device with valid ISO found” during Proxmox setups can be caused by several issues. Here are the common causes and how to fix them:
Causes & Fixes
1. Incorrect USB Drive Preparation
Cause: The ISO file isn’t correctly written to the USB drive.
Fix: Use tools like Rufus or Etcher to properly format the USB and write the ISO file.
2. Ventoy Issues
Cause: Ventoy may not support certain ISO files.
Fix: Use Rufus instead of Ventoy, as it directly writes the ISO to the USB drive and is often more reliable for Proxmox installations.
3. USB Drive Not Detected
Cause: The system may not detect the USB during setup.
Fix: Unplug and replug the USB drive during the ISO detection phase.
4. Grub Configuration
Cause: Incorrect Grub settings can prevent USB recognition.
Fix: Edit the boot options by adding module_blacklist=radeonfb to the Linux line during installation.
5. ISO File Corruption
Cause: The ISO file may be corrupted.
Fix: Re-download the ISO and verify its integrity using a tool like md5sum.
6. System BIOS Settings
Cause: BIOS settings may not support USB booting.
Fix: Enable USB booting in BIOS and set the USB drive as the first boot device.
7. USB Drive Partitioning
Cause: The USB drive may not be partitioned correctly.
Fix: Use a tool like GParted to partition and format the USB drive properly.
8. Incorrect Command Usage
Cause: Incorrect usage of commands like dd or hdiutil.
Fix: Use the correct syntax, e.g., sudo dd if=proxmox-ve_*.iso of=/dev/rdiskX bs=1m.
9. System Compatibility Issues
Cause: The system may not meet Proxmox requirements.
Fix: Ensure the system meets the Proxmox version’s minimum specifications. Consider upgrading hardware if necessary.
