BIOS update failed

[oleonides]

Hello, I'm here to ask for your help guys,

Today my BIOS was being updated and the screen showed completed 100% but it got stuck and rebooted to a black screen so the BIOS got corrupted, I'm trying to restore it by using a USB and by using the keys combination (win + b or v) but it doesn't work, the USB is not being recognized and the BIOS update screen doesn't open.

could someone share with me a suggestion?

thanks for your help.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• Firstly, remove the hard drive from the computer.
  For instructions, see the Maintenance and Service Guide for your notebook model. Locate these in the User Guides section of your notebook product page on the HP Customer Support website.
• Once the hard drive is removed turn on the computer without the hard drive- While booting as the computer doesn’t detect a hard drive so it’ll automatically rollback to the previous bios.
• Put the HDD back in and turn it ON. It might give an error about improper shutdown. Just click continue and it should boot to windows.

Hope this helps! Keep me posted for further assistance.

Thank you so much for your help @Echo_Lake,

I've reproduced all the listed steps but unfortunately it didn't work, I disconnected my HDD as well as my SSD M.2 I turned on the computer I waited for a while and turned it off, I mounted the storage back and turned it on but same issue.
