I want to know how to dual boot my computer with ubuntu 12.04 and windows vista(step by step would be best) and also wanted to know if it would slow down my pc even more than it already is?
- You first install Vista, as you have done it until now.
- You then free up some space with your partition manager. (This is what I use, it is free.)
- You create a bootable Ubuntu USB or CD (details on how to do that on Ubuntu page).
- You install Ubuntu with the option "Install along side Windows."
