Technical Tip: How to fix BdsDxe : failed to load Boot0001 UEFI NUTANUX VDISK in Nutanix Environment

Description

This article describes a failed deployment of a FortiAnalyzer instance when performing VM migrations from VMware (ESXi) to Nutanix.

Scope

FortiAnalyzer.

Solution

Error:

Reason:

1. Wrong boot mode selection: FortiAnalyzer firmware images have strict requirements regarding the hypervisor BIOS type.

2. The boot disk is attached to the wrong bus: FortiAnalyzer images expect the virtual disk to be mapped correctly so the bootloader can initialize.

3. Missing or unassigned secondary data: DiskFortiAnalyzer is a logging and reporting tool; it cannot function or boot correctly without a dedicated storage partition.

Resolution:

1. Change the boot mode in the Nutanix Environment: In the Nutanix Prism console, go to Update VM -> Boot Configuration -> Change the boot mode from UEFI to Legacy BIOS (or Default).

2. Cloned .qcow2 boot image disk: Clone the image and explicitly attach it to the SCSI bus (e.g., SCSI Index 0).

3. Add a new disk to the instance: Create a second, empty disk on the SCSI bus (e.g., 100 GB+ depending on licensing requirements) alongside the primary boot disk.
