Upgrade HP 15-bw049AU laptop from USB - video problem

I discovered this thread because I have the same laptop (bw-049AU) and the same problem.

It turned out that the BIOS was corrupted. An update of the BIOS (from HP) sorted the problem.

Here's some more information about the problem I experienced and what sorted it.

I was getting the scrambled screen when trying to do a fresh install of Win10 from USB.

HP support wasn't recognising the model I had (BW-049AU), but I figured that BW-0xx or BW-000 was probably correct. I downloaded the BIOS update for that model, installed it, and all problems were fixed.

I am also getting the scrambled screen trying to install Windows 10... The BIOS update is a Windows program, isn't it? How do you run it if you can install Windows?

I didn't investigate whether I could install the BIOS from DOS or UEFI. I simply fired up Gandalf's Win10 on a DVD and installed from within Windows.
