how to find info about hardware requirements before installing ubuntu 9.04 software on pc. i currently have Windows Vista S.P2 installed on hard drive.
If it can run vista, it should be able to run ubuntu fine, the only problems you might get is with some more exotic hardware (mostly wireless stuff)
But if you doubt about it, just try to boot a live cd (keep in mind that a live cd is slower then an installed system)
You can find your hardware requirement help and how to install at http://news.softpedia.com/news/Installing-Ubuntu-9-04-110794.shtml or Ubuntu official site http://www.ubuntu.com/.
