Can't upload the program to Arduino Uno My Arduino Uno R3 is not detected by any laptop (I tried 3 laptops). Under devices there is no Arduino port or other devices option. It does not make sound on inserting USB cable. On plugging the USB LED 13 doesn't blink. I is just continuously on. Reset also didn't blink LED 13. Even on external power also it's not resetting.

I checked the USB cable but it's working for my friend's Arduino in my laptop too.

5V Pin giving voltage around 4.96 v, and 3.3 also giving voltage around 3.27 v.

Now I don't have access to any other Arduino for testing. Is there any way to figure out whether the ATmega chip is fried or whether it's a bootloader problem? And how to fix them? Thanks in advance.
While installing the Arduino software,
there are several window pop ups which occur to install the  drivers needed for the operating system to communicate with the device.
Click install to all of them.
