Hi, I wanted to switch to Ubuntu Linux 7.04 yesterday, but I was experiencing some problems. I had searched up a guide to teach me how to Download Ubuntu, burn it as an Image, and install it. But I reached the point of Booting the cd off the CD ROM, and I couldn't. I tried it but it completely disregarded the cd and booted up WinXP. So I looked up some trouble shooting steps. I figured my Bios Boot setup was wrong, so I changed the priority to CD ROM first and Hard drive Last. I tried several times after that but to no avail. I contacted HP to ask for help, but when I mentioned that the Cd was to install Ubuntu Linux, they started to freak out, saying that HP systems don't technically Support Linux. I've have also read that you need to press some buttons so that you can boot a CD, but I don't know which ones. I am currently running on a HP Pavilion 511w. Please help me, Thank you.
