just install itunes
Just sign into your iTunes store, or app store on your Mac with the same Apple ID you have on your HP.
If you have a windows computer you can still download itunes for free. I downloaded itunes on my hp a week ago for free. Just go to the itunes website and you should see an icon on the side that says free download.
If you have a 32bit or 64 bit computer, you have to get the right itunes, or it wont work right.
Depends on that specific HP computer's hardware
You have to have iTunes. That is why it is saying that you need to connect to iTunes. You have to download the latest version of iTunes from Apple's website, and open it up when you have the iPod connected to the computer.
Yes
Yes, an iPod touch will work on a Dell computer as long as it has iTunes loaded onto it.
you dont
If it tells you that you have to then yes but if not probally not
That version of iTunes may not be completely compatible with your computer. For example, you may have downloaded the iTunes for the PC when you have a Mac, or vice versa, etc.
If you just got your ipod then you should connect it to itunes. All you have to do is connect it to your computer.
