instal windows dengan mengunakan usb flahdisk

Someone in this post (Acer Aspire One Specifications and Windows XP Drivers) ask me to write a tutorial about how to install Windows XP using USB flash disk/flash drive.
If you want to install Windows XP, but your notebook (or PC) has no CDROM, you should install Windows XP using USB Flash disk/Flash Drive/Thumb drive...
just follow this guide :


step 1:
Buy an USB Flash Drive (at least 2GB).
When you do this tutorial, please make sure your computer/laptop/PC has a CD-ROM (or DVD).
so, now you have 2 computers, with CD-ROM support and without CD-ROM support (e.g Acer Aspire One, Asus EEE-PC).

step 2:
