PS THESE ARE THE NETBOOKS THAT ARE FROM ACER THERE IS NO DISK DRIVE.. SO THE ONLY WAY OF EXTERNAL INSTALLTION IS THROUGH A FLASH USB DRIVE
Or use a USB (external) CD drive!
You'll need to find all the XP drivers first then put them on a USB stick.
Then if you've got access to an external CD, just install as per normal. You can make do if you have an IDE external HDD then you can pull it apart and remove the HDD and plugin a CD-ROM drive (must also be IDE obviously - I assume the same applies to SATA drive/enclosure but I haven't checked).
If you don't have access to that, then you'll need a USB flash drive (or HDD should do it too). Have a google as there are numerous sets of instructions to install XP from flash drive online. There's probably already one here on msfn.org! Just have a search.
I had a similar issue with my ASUS EeePC when I first bought it, but I stuck with it and I've actually come to like Linux now. Its just different to Windows (ie what you're used to) and once you get your head around the different way of doing things, its not that bad. Although to be honest it was only through the active and supportive EeePC community that many of my questions got answered, which allowed me to persevere. And once I decided to give Linux a serious go I refused to give up. I'm not sure that the Acer Linux has the same support level and without it, it would be very hard for someone to stick with it.
Good luck with it!
