BIOS Update without Windows

Why I decided to update BIOS-

Laptop: HP Laptop 15t dy200

Laptop Issue: 

1. Windows 11 showed blank screen after logging in.  
2. Ubuntu also shows blank screen after logging in for normal mode (non safe mode).
   unless panel screen refresh and power saving states are disabled.

Current BIOS Version: F.33
**Latest BIOS Version: F.40**

Problem:

BIOS update isn't possible on Ubuntu.
Official Website of HP provides BIOS in an .exe file supported for only Windows OS.  

Workaround: Create BIOS USB 

Steps:

1. Create BIOS USB

2. Download BIOS from official website on a working Windows PC
   [Official Website Link: https://support.hp.com/in-en/drivers/hp-15-f2000-laptop-pc-series/model/35900329]

   until BIOS recovery screen comes
