yeah i know i did some reading its just another linux os but how the install wees described basically has wubi in the iso which setsup a second os on the same partition, the only real advantage of this is easier uninstall. whereas normally you would partition your harddrive to the format of the second os the install the os on the second partition. and untinstalled you would have to format the os partition then if you wanted the memory back you would have to delete the second partition and extend your primary partition back out.
