problem uploading to board

Arduino: 1.8.6 (Windows 10), Board: "Arduino Nano, ATmega328P"

Sketch uses 3848 bytes (12%) of program storage space. Maximum is 30720 bytes.
Global variables use 275 bytes (13%) of dynamic memory, leaving 1773 bytes for local variables. Maximum is 2048 bytes.

Did you visit the [linked page ](http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.)for troubleshooting information?

yer but i dont understand whats wrong with it

I don't use 1.8.6. Do you have an option for 'old boot loader's in the band's processor menu? If so, try that. That option is for older original nanos and clones.

// edit: fixed auto correct errors; stupid cell phones.

If you have an older Nano, it uses an older bootloader which is incompatible with the default loader from 1.8.5. You can use and older version of the IDE, updrade the bootloader on the Nano, or with the newer IDE, Once having selected Nano as the board you probably see "ATmega328P" as the processor and carry on to change the port. Go back to Processor and select "ATmega328P (Old Bootloader)".
