How to create Windows XP LiveUSB using Ubuntu to replace it

I am using an Acer Aspire One netbook with no CD-disk drive, and would like to uninstall Ubuntu 12.04 LTS and install Windows XP in its place. The problem here is that I can't seem to find a program that can put the windows boot files on a USB drive from an ISO file. I have Ubuntu fully installed and have tried using unetbootin. When I tried booting from unetbootin I got a screen with a blue box that had the word "default" in it highlighted. underneath the box there was a countdown that said "will boot from default in 10" after the countdown finished the number would revert to ten and nothing would happen. Can someone tell me another program that would be useful for this please?

Solution 1:

Create a bootable Windows XP USB drive:

Download "ms-sys"

Install it.

Partition your USB drive to NTFS.

Now copy the files from your Windows XP ISO to the USB drive

Copy the Windows XP mbr to the USB drive

ms-sys -m /dev/sdX

Replace sdX with the number of your usb hard drive (for example: sda5).

After that, backup your data, then format your drive to NTFS from your Live USB.

You can now install Windows XP through the USB.

Solution 2:

Creating a bootable USB installer for Windows on Ubuntu

Edit: Windows XP doesn't seem to be supported by WinUSB. This method works fine for Windows Vista and up. See here for a different method that works with Windows XP.

WinUSB automates the process of creating a bootable USB stick from a Windows installation disk or .iso file. You can install it either from the .deb package provided on the homepage or through a PPA:

sudo add-apt-repository ppa:colingille/freshlight
sudo apt-get update
sudo apt-get install winusb

The GUI should be straightforward and easy to use:
