I just decided to revive my old computer, its a dell dimension 4700. THe optical drive wasn't working so i also decided to buy a new one. My computer also has an issue where it wont boot up win xp now because it says the file (windows\system\winxp) or something like that is missing and it can't boot (can't see exact name). It also says to insert the setup disc and press r when the screen shows, and I don't have the setup discs for winxp until wednesday or so. So after all the, I'm trying to install ubuntu from a cd i just burned online. When I insert the cd and start my computer it just does the same error over and doesnt ask me to install ubuntu. Yes the ubuntu disc works as well because i tried it in my other computer. How do i get the ubuntu disc to initiate install so I can install that instead of my windows missing a vital file? Is it something to do with setting bios to initiate optical drive boot first? And could whoever answers give me a detailed answer I want to follow step by step. THanks!
