The Linux XP 2010 that I downloaded here
is 2.8 GB ,so I'm not at all sure we're talking about the same OS..
but the steps to install are basically the same for all of them..
1 boot off your installation media (ie-the flash drive in the case of your netbook)
2 start the install
3 partition your hard drive if you want to/have room to dual boot with your current OS (Windows?),or partition to just install Linux XP (or any distro) by partitioning manually,or just choosing "use entire drive" or something close from the partitioning options
4 fill in your info(name,login name and password,etc) and answer a few other questions (language,keyboard,etc)
5 sit back and wait for the install to finish
steps 3 and 4 are sometimes reversed from this order..
good luck and have fun learning!
