How to get my old Itunes library on a new computer?

I have tried using my Iphone but it wants to delete all my music and sync it to my new itunes. Also, my laptop crashed but i was able to save the hardrive on a USB. So if anyone knows how to do it with the phone or the USB, help would be appreciated.

  • Will downloading a new iTunes ruin my old iTunes library? I tried connecting my new iPhone 5 to my iTunes but it said that it wouldn't connect because my version of iTunes was really old (from 2010) and I never updated. It said I need to download a new version of iTunes (10.7 onwards) for it to be compatible with my iPhone. But my question is, IF I download a new version of iTunes, will all my old songs on my old iTunes disappear? Because if I had to re-download my whole library, I would seriously cry. That would take the rest of my life.
