Hi ,
I have been trying to enable Secureboot to my board having Intel-x86 architecture  and I am following the steps given in this link https://github.com/jiazhang0/meta-secure-core for Yocto Dunfell branch.

Problem: In non Secureboot mode Yocto Boots normally and everything works fine but when Secureboot is enabled till grub it boots and loads grub-menu then after
If I press boot option it will simply throw this error 
verification requested but nobody cares: bzImage
and stucks there.

I am not getting why this error is coming and what fixes to be made.

BTW grub version is grub-efi-2.04.

Below are the local.conf settings for Secureboot.

UEFI_SB = "1"
BUNDLE = "1"
GRUB_SIGN_VERIFY='0'
GRUB_SIGN_VERIFY_STRICT='0'
DEBUG_FLAGS_forcevariable = ""
IMAGE_INSTALL += "kernel-image-bzimage"
USER_CLASSES_remove = "image-prelink"
MASTER_KEYS_DIR = "/home/yocto/poky/meta-secure-core/meta-signing-key/scripts/user-keys"
 
IMA_KEYS_DIR = "${MASTER_KEYS_DIR}/ima_keys"
IMA_EVM_KEY_DIR = "${MASTER_KEYS_DIR}/ima_keys"

GRUB_PW_FILE = "${MASTER_KEYS_DIR}/boot_keys/boot_cfg_pw"
OSTREE_GPGDIR = "${MASTER_KEYS_DIR}/rpm_keys"
 
RPM_GPG_NAME = "PKG-SecureCore"
RPM_GPG_PASSPHRASE = "root"
RPM_FSK_PASSWORD = "root"
BOOT_GPG_NAME = "BOOT-SecureCore"
BOOT_GPG_PASSPHRASE = "root"
OSTREE_GPGID = "PKG-SecureCore"
OSTREE_GPG_PASSPHRASE = "root"
OSTREE_GRUB_PW_FILE = "${GRUB_PW_FILE}"
I am stuck with this issue from last 5 days ,please help me to solve this issue.

Thanks and Regards
