Windows 10: How can I reflash a corrupted bios using a usb stick?

The BIOS of my lenovo ideapad 320 15-AST is corrupted so when I boot the laptop, the screen remains blank. Is there any way I can write the bios to a USB stick and automatically boot the computer into it and then reflash the BIOS?

Can UEFI BIOS get corrupted?

I suggest you run the built in HP diagnostics and contact HP support if covered. I've had a corrupted BIOS on my desktop PC which required the BIOS to be reflashed. See this method to recover a HP BIOS https://support.hp.com/gb-en/document/c02693833

9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

 

How can I reflash BIOS? Is possible??

Are you asking after a BIOS update or a fix for a BIOS update that has gone wrong?

If it's the latter: some makers have a BIOS recovery mode where you can flash from a USB drive even if the existing BIOS on the machine is too corrupt to allow the machine to boot normally. I don't whether any laptops support this. As you haven't told us what your system is, it's not possible for me to check.
