Error while burning bootloader.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

please help

According to the error, there are two errors, one is opening the communication port and the other one is for the bootloader file not found. Try Uninstalling and Reinstalling the Arduino IDE and check your connections before burning the bootloader. This might fix both the problems.


One thing at the time. First of all you have have the port ready and functional. Check it in the OS device manager whether it exists, driver, access, rights, not blocked by other APVs like antivir.

The duplicate thread started by the OP has been deleted

You can't burn a new bootloader using the old bootloader. You need an ISP device. You can use an Arduino UNO running File->Examples->11.ArduinoISP or you can spend $5 and get a USBasp and 10-pin to 6-pin ICSP adapter from eBay.
