Win7 upload issue, plzzzzzzzzzz! QAQ

Development Tools IDE 1.x
1

The board is Arduino Nano V3.0 328ATmega, using win7 system, and IDE version 1.6.4. When nano connecting to the computer, it said "driver installed successfully", and I found A new USB Serial Port in the devices manager, COM10. Before uploading, I selected board:nano; processor: ATmega328; com10; programmer:AVRISP mkII（default）.
But uploading always fails.
P.S Thanks for @CrossRoads, after reloading the bootloader, this problem is solved. But I got another problem:
"avrdude: stk500_getsync(): not in sync: resp=0x00"
The RX LED flashes only three times at the beginning of uploading, then goes out while the uploading process is still continuing.

The original problem:
When uploading fails , it says:

Arduino:1.6.4 (Windows 7), Board："Arduino Duemilanove or Diecimila, ATmega328"

I thought you said you selected Nano?

When uploading fails , it says:

Arduino:1.6.4 (Windows 7), Board："Arduino Duemilanove or Diecimila, ATmega328"

That doesn't look like Nano.
Are you sure the Nano has a bootloader installed?

The official website says the board selection can be nano or duemilanove, I tried both and got the same type of problems. Yeah, I copied the infor of duemilanove from thousands of damn same false trials.

Do you have another that works?

You could try reloading the bootloader onto the Nano. If you select Uno as board type, you can check the board out.

Thank you! I reloaded the bootloader, this problem seems to be solved. But I got another one, avrdude: stk500_getsync(): not in sync: resp=0x00. Only this sentence and I'm sure the TX1 pin and RX0 pin are free. When I upload code, the RX LED flashes only three times very quickly at the beginning, then it went out while the upload process is still continuing.
P.S. For the Nano, "FTDI FT232RL on the board channels this serial communication over USB."
