If you somehow hate Microsoft badly with their OS .. chances are .. you might want to use linux as your operating system .
Since I already use Fedora 7 as my other OS (dual boot with Windows Xp Pro SP2) I cant try this software . this is call Wubi . If you already a windows user and NOOB in Linux in this case Ubuntu distro .. u can use this software inflatable christmas decorations canada . U can always change to use windows or ubuntu .. and it doesn;t effect your MBR or anything ..
I am fedora fanboy .. so .. hopefully there will be installer for fedora . =)
