I have used it for several months and this problem has occurred many times. I don't really know how it I fixed it when it has happened, but somehow it has been fixed before. I have IDE 1.0.5. I have Windows7 on a HP tx1308nr laptop computer.
It came with the official starter kit.
It shows up in device manager. It also shows up in devices and printers. There is no yellow exclamation mark next to the listing in device manager. I have occasionally used a Bluetooth USB dongle which I think has caused problems. When I use the Bluetooth dongle it makes 3 ports and one of them always has a yellow exclamation mark and installing the driver doesn't fix it but it works fine for music.
Yes the Uno board is selected.
I have tried the following troubleshooting steps in many combinations of orders:
unplugging and replugging the usb cable.
plugging the usb cable in a different port.
unplugging all other usb devices.
selecting different com ports on the ide.
restarting the ide.
resetting the uno.
restarting the computer with and without the uno plugged in.
uninstalling and reinstalling the driver.
disabling and re enabling the port/driver.
From device manager, rt clicked properties, selected port settings tab, selected advanced, selected a different com port number for the device.
scan for hardware changes in device manager.
tried to launch the serial monitor instead of uploading, sometimes there has been an error, lately it starts with no error but uno doesn't respond, according to the last sketch, it should.
tried to upload different sketches, including a very simple clear sketch.
Someone told me to burn the bootloader but I haven't done that before and I don't know what that is except what I find by searching online.
I think the Uno is malfunctioning, because I can select a different com port number through the device manager and the new com port number shows up in device manager as the uno, and also I see the new com port number with the uno in devices and printers, and the new number shows up in the IDE and I can select it. At that point, if I try to upload a sketch I get the AVRDUDE error which is getting extremely frustrating to work on a sketch all day and then it won't upload.

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"
enabled in File > Preferences.
I turned on the verbose uploading option and re-ran the upload, here's the output along with some screen shots:

If it still shows in Windows I doubt it's the bootloader. More specific, I doubt it's the Arduino. Most of the time you get that message when another program is using the same COM port. Maybe it's the bluetooth software that's just retarded and tries to connect every COM port it thinks it's the bluetooth.
Can you try another PC? Preferably one you didn't ever plug in the bluetooth adapter...

The Arduino platform is a low-cost introduction to micro-controllers. The designers have made the software and hardware design open-source. The software is free. Try moving to another platform, you may find that the software is not free.
For the tiny amount of money you spend on the hardware, you can get free technical support from this forum, staffed almost entirely by unpaid volunteers. You will get a better response if you ask questions respectfully rather than shouting them. Also you might reveal more details about what is wrong.
It is possible (indeed quite likely) that you have a cheap knock-off clone which you bought for around $3. These cheap clones are not as reliable as the original hardware, which itself is quite cheap.
Perhaps, if this is the case, you could address your frustration to the vendor on eBay who sold you this junk.
I just bought a brand new fully functioning raspberry pi 2 model b and an Intel Edison.
I have posted about this problem for a month or so and no one helped me, and because of the problem I MISSED A VERY IMPORTANT DEADLINE BECAUSE OF IT. SO I SHOUTED TO GET SOMEONE'S ATTENTION. AND THE REASON I "CROSS POSTED" whatever that means IS BECAUSE ITS A DIFFERENT ERROR IT CHANGED AFTER I INSTALLED THE NEW IDE 1.6.6. AND NO ONE HELPED ME WITH THE FIRST ONE.
I have spent hundreds of dollars on related equipment so it's an important issue for it to be malfunctioning.
I have posted many details including a long organized list about the problem and apparently YOU didn't even bother to check before you decided to childishly "judge me" and "cast me away". What great treatment of your customers. I guess I should have known this is how it would be, buying a product with no tech support. Never again.
Guess what its the real thing I paid over $100 for it at my local Microcenter, attached are the photos. And here's another picture of the error.
For as much money that they are making on this there should be paid technical support.
I didn't "Shout" at anyone I wrote text in upper case letters. I didn't even "shout", or however you interpret it, at any specific person it was for anyone to read.
If you are upset by some words on a screen written in UPPER CASE LETTERS, or are so sensitive that the occurrence of someone asking for help from additional people on a difficult problem makes you upset and spew negativity then you probably shouldn't be a forum moderator or work in any kind of customer assistance.
I got the same error message and was wondering what was the problem. I checked my boards and I couldn't find one saying "Arduino Uno". what do i do now?
Yep and that's the problem, you think being a 'volunteer' gives you the right to do and say what ever you want and treat people however you want because there's no accountability. I'm pretty sure the company would be interested to see how you are representing them however.
