I am using Windows 10 64 bit and I have added the pc-bios folder to PATH if that matters. I have tried the following commands till now: Windows terminal screenshot

You can use bios-256k.bin that comes with QEMU. Add the following while running your command ... -L "C:\Program Files\qemu". Where "C:\Program Files\qemu" is the path to QEMU installation.

@Mina Maged Why is this required and when is this required? Is there a command that works for any operating system? – David Callanan Jul 20 '21 at 11:07

Add -L C:\Users\Ratul\AppData\Local\Android\Sdk\emulator\lib\pc-bios\ option to your command line. You tried this option, but used the path and name of the binary, and iIt should contain only the path.
