I’ll describe here how you can easily install Kubuntu in your PC.
First, download ISO here, unfortunately only have DVD version.
Burn it, and boot. It will ask about language.
After selected the language Portugues do Brasil(Portuguese of Brazil, my default language), press enter. Now select Install Kubuntu and press enter again.
It may take a while to load, it all depends on your computer and the media used.
At the end of boot you will be asked (again) on the language. What you chose is already chosen by default, press Next.
He will try to get the current time, just a little patience.
After getting it, you will be asked about the time zone, in my case, Porto Velho/Rondônia
Next will be the turn of the keyboard layout, because I’m using the language Portuguese of Brazil it defines the default brazilian layout(abnt2) by default
Finally the most delicate, in that case let him use the whole disk, if you need to do different then search on google how to do this
Now it will ask the User Information, fill name and it will automatically put your first name as login (you can change it), put your password, repeat it, put a name to your computer and in bottom, select the options you want, as in my computer is used only a User, I chose Automatically sign.
If you use a weak password like me, will be shown a window warning about it. It is possible to ignore it, but it is advisable to place a stronger password
At this point you are at the last step that requires human administration. With all the information that will be done, you should look and see if everything is right and press Install, otherwise press Back, and fix it.
The first thing he will do is fix the partitioning, this point, you can go for a ride:)
After partitioning it will calculate which files should be copied.
In 80% it will configure apt and download the translations, if you are connected to the Internet. If you prefer you can cancel this part.
Finally the end, time to restart and configure :)
