Describe the bug
I installed Harvester on my Dell Optiplex 3060 (UEFI, Secure Boot disabled) using the join cluster option but after installation, it boots with the following error message:

Invalid image
Failed to read header: Unsupported
Failed to load image: Unsupported
start_image() returned Unsupported

To Reproduce
Steps to reproduce the behavior:

1. Download harvester-v1.1.2-amd64.iso
2. Create bootable USB using BalenaEtcher
3. Boot from USB
4. Go through installation steps, here is the final screen:

5. Installation successful, reboot into boot device (Boot USB Detached)
6. Get following error:

Invalid image
Failed to read header: Unsupported
Failed to load image: Unsupported
start_image() returned Unsupported

Expected behavior
Expected Rancher Harvester to boot properly and show it to be added to my cluster

Support bundle
I cannot get this from the device since it doesn't properly start up

Environment

• Harvester ISO version: v1.1.2-amd64
• Underlying Infrastructure: Baremetal with Dell Optiplex 3060

Additional context
It may be due to some bios setting, but any relevant settings have been set:

• Secure Boot disabled
• UEFI Boot enable (I even tried legacy boot)

View Boot Option shows the following:
