[ubuntu] Instaling Windows XP after ubuntu is installed

view story

http://ubuntuforums.org – Hello, Is there anyway I can install Windows XP on my ubuntu laptop so that it can dual boot (So I can choose which operation system i want on system boot) I know people usually install windows first but i cant do that because i dont have access to a usb and my laptop has no cd slot. So is there a way to create a second partition or something and then download a windows XP iso on to that partition so then i can dual boot on my laptop. I dont want to use Wine, Or Virtual box they are very slow :( Thanks, I dont have usb or cd :L im using ubuntu 12.04 lts and i want windows xp :( (Hardware)
