[Windows XP] Dual boot xubuntu/WinXP

Hi there,

got 200GB hdd. +- 150GB reserved via GParted for xubuntu 15.04. Another partition, +- 50GB, is formatted in ntfs. There i want to install Win XP - got iso.

But.

These methods i've tried:

Unetbootin - simply caot boot, as there was nothing.
Multiboot - after given command "boot" says that something must be done to the keel, which i caot find out at all, or it simply freezes
WinUSB - i can't even run this thing, simply nothing happens when trying to run
http://askubuntu.com/questions/15107...-to-replace-it - post from "upapilot" - when i select flash drive to boot i get only black screen with "_" flashing.

Is it only my programming noobiness what's causing the trouble?

You, who actually reads this, can you help me, please?
