Installing windows with ubuntu

view story

http://askubuntu.com – Ive made about 50 bootable flash drives and every time i try to install xp, 7 or even 8 i get missing BOOTMGR errors. I have tried all fixes i have found and none seem to work. i have come up with 2 ideas though. 1, mount the iso inside a VM of windows, or use ubuntu live cd to edit my hdd with the partition i will need and use ms-sys to install a bootmgr directly to the partition. if there is an easier way please let me know. Burning the iso is not an option as i have no money for blank cds or dvds. On that subject though, if i happen to get a blank cd can i burn an xp iso with brasero on a c (HowTos)
