Arduino Startup & buring Bootloader

Absolutely new to Ardinuo , but am fairly computer literate :slight_smile:
Using windows7 (64 bit) on a PC connecting to Arduino with USB cabe.
Two red LEDs com on (pin 13 & ā€œLā€ )

what exactly are you trying to accomplish?

Burn a bootloader using an USBtiny on an Arduino?

Your Arduino should have come with the bootloader already installed. Just connect up the USB cable and upload a sketch.
