# 5. Enroll the certs in firmware
# Boot into UEFI shell, run FS0:\EFI\Boot\KeyTool.efi.

# In KeyTool:
# Go to Edit Keys → KEK → Add New Key, pick kek2023.cer.
# Go to Edit Keys → db → Add New Key, pick db2023.cer.
# If no PK is present yet, you must enroll a Platform Key (PK) first (can be self-signed with OpenSSL; KeyTool can also generate). Without a PK, Secure Boot remains “greyed out.”

# ✅ After PK + KEK + DB are enrolled, reboot → go into firmware setup → Secure Boot option will be toggleable → set it to Enabled.
# Now Windows 11 installer/bootloader should run under Secure Boot.
