ESXi Secure Boot is failing - Dell powerdge r640
Trying to install ESXi 7.0.2 in UEFI mode with secure boot enabled. Under loading of ISO it complains about secure boot can not be enabled and ends with purple screen of death. I am getting the error message "UEFI Secure boot failed: Failed to verify signatures of following vib(s)".
Have enabled UEFI and secure boot in BIOS and updated to latest available BIOS.
No Events found!

Hi, From what I've seen here it looks like the cause of this PSOD is related to the description here. ESXi Secure boot workflow
"
The mboot boot loader in ESXi contains a VMware public key and is validated against the Certificate Authority (CA) present in the platform BIOS UEFI Secure boot authorized Database (DB) during ESXi boot. The boot loader uses this key to verify the signature of the kernel and a small subset of systems that includes a Secure boot VIB verifier—a VIB package that is used for validating the signature of the drivers and other VIB packages that are loaded from the boot device. If any of the VIB installed on ESXi does not match with the signature of the public key that is contained in the bootloader, then ESXi boot ends up with the Purple Screen Of Death (PSOD) mentioning a signature mismatch for the specific failing VIBs."
Can you check the secure boot in the video here,
Enabling Secure Boot https://dell.to/33uEgae
Can you also check this article,
Cannot enable secure boot on ESXi 6.5 or 6.7 host that was upgraded (2147606) https://dell.to/3I3yhsa
UEFI Secure boot is supported only on Dell EMC's YX3X PowerEdge servers or later. Naming your server should be in YX4X systems I don't think it will be a problem here.
Hope That Helps!
