HP BIOS Update Triggers BitLocker Loop on Windows 11

HP Confirms BIOS Update Causes BitLocker Recovery Loops

According to recent reports, HP has acknowledged that its latest BIOS update is causing severe issues on many of its premium commercial laptops and workstations. Users who installed firmware updates released in early April 2026 are encountering endless BitLocker recovery loops, rendering their systems unusable.

The problem stems from the BIOS update interfering with Microsoft's Secure Boot 2023 certificates. When the update is applied, it blocks the proper installation of these certificates, triggering BitLocker's recovery mode on every boot. This leaves users stuck in a loop, unable to access their data or operating system.

Impact on Windows 11 Devices

The issue primarily affects HP's high-end business devices running Windows 11. Affected models include the EliteBook, ZBook, and ProBook series. Users report that even after entering the BitLocker recovery key, the system reboots and prompts for the key again, creating an infinite cycle.

HP has released a statement confirming the problem and is working on a fix. In the meantime, the company advises users who have not yet installed the update to delay installation until a corrected version is available. For those already affected, HP recommends contacting support for assistance, though no immediate solution has been provided.

Workarounds and Next Steps

Some users have found temporary workarounds, such as disabling BitLocker before installing the update or rolling back the BIOS to a previous version. However, these steps require administrative access and may not be feasible for all users. HP is expected to release a patched BIOS update within the coming weeks.

This incident highlights the risks associated with firmware updates and the importance of testing before widespread deployment. Businesses relying on HP devices should exercise caution and monitor official channels for updates.
