Your HP BIOS update has stopped moving, the screen is black, or Windows won't start afterward. The right fix depends on where it stopped. Start below to protect an installation that's still running, recover a failed startup, or retry a download inside Windows.
Give the update time to finish
Waiting protects an installation or automatic recovery that's still running. Keep AC power connected throughout the update.
Wait at least five minutes before troubleshooting a blank startup screen. HP says firmware updates can temporarily blank the display. Five minutes is not a shutdown deadline, and HP provides no universal elapsed-time cutoff for safely interrupting an active flash.
Let automatic BIOS recovery finish if it starts after a failed update. Recovery also uses a black screen, so leave power connected while it runs. Press Enter when the recovery confirmation appears, or allow the automatic restart.
Check your product specifications or startup logo for HP Sure Start before attempting manual recovery. Sure Start-equipped PCs use automatic firmware repair and do not support manual Windows+B or crisis-recovery USB methods. Contact HP or your organization's IT department if Sure Start repair repeatedly fails.
Power-reset a PC that no longer starts
A power reset does not erase personal files; use it after a failed startup, never during an active BIOS installation or recovery.
- 1.Shut down the computer.
- 2.Unplug AC power.
- 3.Remove discs and memory cards, and disconnect unnecessary USB devices and docking equipment. Leave a desktop's keyboard, mouse, and monitor connected.
- 4.Remove the battery only if your notebook has a user-removable battery. Do not open a sealed-battery notebook for this procedure.
- 5.Hold the Power button for approximately 15 seconds.
- 6.Reinstall a removed battery, reconnect AC power, and start the computer with unnecessary peripherals still disconnected.
Restore firmware settings after a failed startup
Restoring defaults addresses incorrect firmware settings after an update. It does not replace a corrupted BIOS image. The consumer CMOS procedures below do not apply universally to business models.
On a consumer HP notebook that can open firmware setup, start the computer while repeatedly pressing F10. Select Exit > Load Setup Defaults, confirm the reset, and save the change.
For a compatible consumer notebook that cannot reach setup, connect AC power before using HP's keyboard CMOS reset. Shut down the notebook, wait five seconds, and hold Windows+V.
While keeping those keys held, hold Power for two to three seconds. Release only Power, keeping Windows+V held until the CMOS reset screen or beeps appear. This clears firmware settings; it is separate from BIOS-image recovery.
On a consumer HP desktop or All-in-One covered by HP's CMOS reset procedure, keep AC power connected. Hold Power for more than 20 seconds, then release Power to let the computer boot and display confirmation that defaults were loaded.
If restoring settings does not resolve the failed startup, try the supported BIOS recovery shortcut next.
If the PC cannot boot, try BIOS recovery
Manual keyboard recovery applies to compatible HP notebooks and desktops without Sure Start. Neither recovery shortcut works on every HP model.
With the computer off, connect AC power. Hold Windows+B, then, while keeping those keys held, press Power for two to three seconds. Release only Power, continuing to hold Windows+B.
On a compatible notebook, allow automatic recovery to start. On a desktop, wait approximately 40 seconds for the recovery screen. If a notebook shows no recovery screen, repeat the sequence using Windows+V instead. If a desktop shows no recovery screen, retry by pressing and releasing Power.
Then repeatedly press Windows+B. Allow recovery to complete with power connected. On a desktop, select Continue Startup when recovery finishes. On a notebook, press Enter at the recovery confirmation or let the computer restart automatically.
Create a recovery USB for a failed BIOS
A recovery USB supplies the BIOS image when keyboard recovery alone fails on a supported PC. Identify the failed computer's exact product and motherboard identifiers. This method requires a matching HP BIOS package with recovery-media creation and is unsupported on Sure Start PCs.
On another working Windows computer, open HP's Software and Drivers page. Choose Laptop or Desktop, then identify the failed PC by its product or serial number. Review the BIOS package's applicability against the failed PC's identifiers.
Download the matching package, selecting Download only if the download assistant appears. Run the downloaded package, approve the installer prompts, and accept the license.
Choose Create Recovery USB flash drive, then select Next. Select a blank USB drive. HP prohibits USB Type-C flash drives for crisis recovery on Intel notebooks.
Select Next to copy the recovery files. Finish the utility after copying completes. Shut down the failed computer and leave it off for five to ten seconds.
Connect its AC power, insert the prepared recovery USB, and hold Windows+B. While keeping those keys held, press Power for two to three seconds.
Release only Power, retaining the keys. Some supported notebooks require Windows+V instead. Let recovery finish with power connected. Contact HP for model-specific assistance if the package lacks the recovery-media option or recovery repeatedly fails.
When Windows still works, fix the update delivery
Use this route when the download or updater app stalls inside Windows and the computer remains usable. These steps belong before another installation begins.
For a Windows Update download or staging problem, open Get Help, then search for windows update troubleshooter. Follow the diagnostic prompts and restart the computer afterward. Open Check for updates to check again. The troubleshooter repairs delivery inside Windows; it does not repair a frozen preboot flash.
For a malfunctioning HP updater, download the exact PC's BIOS package from HP's Software and Drivers page using the identification steps above. Manual installation bypasses the update app.
Connect AC power, close your open applications, and have your BitLocker recovery key available if the drive is encrypted. On a PC using BitLocker with its management controls available, open Manage BitLocker.
Select Suspend protection, then select Yes to confirm. Temporarily disable antivirus through its protection controls, as HP advises for the update. The control names depend on the antivirus product.
Run the matching BIOS package and approve the installer prompts. Accept the license, then select Update in HP's update utility.
Select Next, then select Restart Now. Choose Apply Update Now when prompted. Allow installation to finish with power connected.
Select Continue Startup after the update completes. Open Manage BitLocker again, select Resume Protection, and re-enable antivirus protection.
Get help when startup remains blocked
Check the screen for a BitLocker recovery prompt before attempting another recovery. After a BIOS change, that prompt requires the drive's recovery key.
Record the recovery-key ID shown on the screen. On another device, open Microsoft's recovery-key page. Sign in to the Microsoft account used to save the key. Find the saved key whose ID matches the one on the affected computer.
Enter the associated 48-digit recovery key on that computer. Check saved printouts or USB backups if the key is absent from your account. For an organization-managed PC, obtain the key from IT.
If BIOS recovery cannot start or repeatedly fails, record the update stage, exact error text, blink or beep pattern, and recovery attempts. Open HP Support. Select Contact an HP agent for Support, then identify your exact product.
Provide the recorded details when requesting model-specific recovery or repair. Keep the product information and error details handy so support can match the recovery procedure to your hardware.
Frequently Asked Questions
Can I uninstall HP Support Assistant to undo a BIOS update?
No. Removing HP Support Assistant does not uninstall a flashed BIOS. Reinstalling the app addresses application problems while Windows still works.
Does HP Support Assistant work in Windows S mode or on ARM PCs?
No. HP Support Assistant is unavailable in Windows S mode and on ARM processors. HP directs ARM users to its official Software and Drivers page. Windows Update also delivers applicable HP firmware in Windows 11, including S mode, when HP publishes it there.
Can I update the BIOS directly from F10 setup?
Yes, on supported HP business notebooks and desktops that expose the Check HP.com for BIOS Updates option. This requires working BIOS setup and network connectivity. Your organization's managed settings determine whether you can access it.
