Can't uploading program to board

Mr and Mrs , can you help me I can't uploading to board arduio uno
and show this massage

Arduino: 1.8.8 (Windows 7), Board: "Arduino/Genuino Uno"

Sketch uses 5420 bytes (16%) of program storage space. Maximum is 32256 bytes.
Global variables use 284 bytes (13%) of dynamic memory, leaving 1764 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

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

Thanks before

Correct board selected (is it indeed an Uno)?
Correct port selected?

Is this a clone or an original? What happens in Windows device manager when connecting / disconnecting the board? The port that shows there under ports (com and lpt) should be the one that you need to select in the IDE.

thanks sir,

the ports (com & LPT)on device manager is working properly,
it detected on port in my computer,
and i try on other computer it's the same ,finally it doesn't upload the program,
are there indications of damage on board?

Is it a cheap chinese clone Uno?

If it is, try the other boards that use an atmega328p (Nano with processor -> 328p (old bootloader) and Pro Mini) - they occasionally ship boards with a bootloader that doesn't match the board.

When you press reset button, does the light blink?
When the upload is attempted, does the light blink in the same pattern.

thanks sir

that's very helpful, maybe my board is clone and doesn't match ,

can u show me Link website? where i can buy the original product ?

If it's detected in device manager as e.g. COM3, that is what you need to choose in the IDE. And in that case it's not a driver issue.

Did you try DrAzzy's suggestion to try e.g. Nano (tools -> board) with old bootloader (tools -> processor) ?

You can buy original Unos at a lot of places; the Arduino store is the place where it's guaranteed to be an original.
