This message means your PC’s UEFI firmware rejected the selected Windows Boot Manager under its current Secure Boot policy. It does not, by itself, prove that Windows or the drive is damaged. Start by checking what changed and whether the firmware still sees the Windows drive and boot entry; then use the PC maker’s model-specific instructions before changing Secure Boot settings.
What the message means
Secure Boot runs in UEFI firmware before Windows starts. It checks signatures in the boot chain, including the Windows Boot Manager, against firmware databases of permitted and revoked signatures. A revoked signature takes precedence over an allowed entry. If the firmware does not accept the selected boot manager under that policy, it blocks it from running.

The wording does not identify the reason for rejection. A change to firmware settings, a mismatch between the firmware’s trust configuration and boot software, or another device-specific boot issue could be involved. The message alone does not establish that the boot files, disk, or Windows installation are corrupted.
What to check before changing firmware settings
- Note what changed. Record whether the problem began after a BIOS/UEFI update, a Secure Boot setting change, a Windows reinstall, or a change to the boot device. These details can help the manufacturer narrow down the cause.
- Check whether the drive and boot entry appear. In UEFI settings, look for the Windows drive and an entry named Windows Boot Manager. Firmware menus and labels vary by model. If either is missing, consult the PC maker’s support instructions rather than assuming Secure Boot is the only problem.
- Use the manufacturer’s directions to reach UEFI settings. Microsoft explains that Secure Boot is generally managed in BIOS/UEFI, and that menu names and access methods vary by manufacturer. On supported PCs, Windows Advanced startup may offer a route to UEFI Firmware Settings: Microsoft’s Secure Boot guidance.
Use Secure Boot changes as a diagnostic clue, not a blanket fix
If temporarily disabling Secure Boot lets the PC start, that suggests the rejection is related to the firmware’s Secure Boot policy, but it does not identify the underlying cause. Treat the test as temporary and follow the PC maker’s instructions to restore Secure Boot when appropriate. Microsoft warns that firmware changes can prevent a device from starting and recommends contacting the manufacturer if Secure Boot cannot be enabled or disabled as expected.

Do not clear, replace, or restore Secure Boot keys as a generic repair. Some PCs may have an option to load built-in keys, but the available controls and risks differ by model. Microsoft also discusses resetting BIOS to factory settings in some circumstances; do not use that as a universal step, since a reset can change other firmware settings. Get model-specific guidance before proceeding.
When to contact the manufacturer
Contact the PC manufacturer or qualified support if the boot manager remains blocked, the firmware cannot see the drive or Windows Boot Manager, or you cannot safely restore Secure Boot. Provide the device model, the exact message, when it began, and any recent firmware or boot changes. Microsoft’s guidance also recommends manufacturer help when Secure Boot changes continue to fail.

How the June 2026 certificate date fits in
Microsoft says Secure Boot certificates issued in 2011 begin expiring in June 2026. Devices that have not received the relevant updates may still start and receive ordinary Windows updates, but may not receive future Secure Boot protections for early-boot components. That transition is useful background, not evidence that certificate expiration caused a particular PC to display this message: Microsoft’s Secure Boot certificate information.

A Microsoft Q&A user described one Lenovo IdeaPad Gaming 3-15IMH05 (Type 81Y4) case in which restoring factory keys and other attempts did not resolve the issue; the user reported success booting SecureBootRecovery.efi from a FAT32 USB drive. This is one user’s account, not official general guidance.
