,
Thank you for posting on HP Forums,
The Barachiel is at your service.
I understand you are in need of support,
I'll be glad to help you out, however, for an accurate solution I will need more details:
Have you attempted any steps on your own before posting on the HP Forums?
When was the last time it worked without these issues?
In the meantime, please try the steps mentioned below:
Step 1: Recover the BIOS using a key press combination
Many HP notebook computers have an emergency BIOS recovery feature that allows you to recover and install the last known good version of the BIOS from the hard drive, as long as the hard drive remains functional. This emergency recovery feature is separate from the BIOS and is designed to work in the event of a catastrophic BIOS failure.
Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key
and the B key at the same time.
NOTE:
On some notebook models, it might be necessary to press and hold the Windows logo key
and the V key.
While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key
and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).
The HP BIOS Update screen displays, and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.
If this doesn't help, then
Step 2: Download a replacement BIOS file
If the HP_TOOLS volume (Windows 7) or UEFI partition (Windows 10, 8) on your hard drive has been deleted, or if the emergency BIOS recovery feature did not resolve the issue, download a replacement BIOS file.
To complete this step, you need another working computer with an active Internet connection.
Go to HP Software & Driver Downloads.
Type the model number of the notebook that is not starting in the Enter your HP product name, product number or serial number box, for example, HP ProBook 645, and then click Find.
If a list of model numbers displays, select your model number from the list.
In the Software and drivers results page for your model, make sure the Detected operating system is correct. If necessary, click Change, select your operating system and version, and then click Change.
Click BIOS.
If you want to view more information about the BIOS update package, click Details.
Click Download next to the BIOS update file, and then save the file to your computer when the download completes.
Make sure to note the location of the saved file.
If multiple BIOS files are available, click Download next to the most recently released file or the one you need (if a specific BIOS file was recommended for restoring your notebook).
Step 3: Create a BIOS recovery flash drive
Use HP BIOS Update and Recovery to create a BIOS recovery flash drive.
To complete this step, you need a blank USB flash drive. The flash drive does not need to be bootable.
Connect a blank flash drive to the working computer.
Navigate to the BIOS file you downloaded and saved, and then double-click the file.
If a User Account Control window displays, click Yes.
The InstallShield Wizard opens.
Click Next.

Remove the flash drive from the computer.
Step 4: Recover the BIOS using the recovery flash drive
Use the HP emergency BIOS recovery feature and the recovery flash drive to restore the BIOS.
Shut down the notebook that is not starting, and then wait 5 to 10 seconds.
Plug the notebook into a power supply using the AC adapter.
Connect the BIOS recovery flash drive to the notebook.
With the notebook off, press and hold the Windows logo key
and the B key at the same time.
While pressing those keys, press and hold the Power button on the notebook for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key
and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).
The HP BIOS Update screen displays, and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.
If the HP BIOS Update screen does not display after repeated attempts, your notebook might not support this function, or there might be a hardware problem preventing the tool from opening.
If that's the case, I'd request you to contact HP's phone support team for further assistance.HP Support can be reached by clicking on the following link: Open link: www.hp.com/contacthp/
