4. Now it remains to write a text document. You create it in your flash drive. Call it amiflash.bat - this file will help start the flashing process. The file contains the following data: amiflash flash.bin / b / d / e / g. Such startup parameters work in most cases.
5. The main work is completed. Now restart the computer, open the BIOS, and there is a Boot tab in it. There, specify your bootable media first to boot. In the console, issue amiflash.bat.
