A while ago we bought Jessica an Acer Aspire One running Linux (this is the cheaper option, the XP ones were about double the price at the time).
She got tired of that and asked me to install Windows XP.
I tried following the tutorial , which involve putting XP on a memstick, but I gave up on that, borrowed the external USB CD drive from work, and installed from the CD. That worked well.
You’ll need to download the drivers here.
