What do you mean help you install it? There are 3 different ways of installing it.

Well there is a couple ways of doing this. The simplest way in my opinion is this way:
Through this installer located [ Register or Signin to view external links. ] . You just download the installer and run it. The installer is pretty self explanatory and there is no bootloader to worry about. It will automatically use the windows bootloader. If you want to installed the grub 2 filesystem and bootloader you can. It looks a little better then Windows bootloader but they both do the same thing.

first download the iso from the website
burn it to a disc
go to disk manager
and make a partition that is 50gb big youtube (how to make partition)
put in the disc
boot from cd / dvd
go through installer untill it says "install instead of xp , along side of xp or something else"
select something else
select your 50gb partition
select it, select EXT4 FORMAT
and set the boot to \
install
enjoy

plese +rep me!
