hi all

i have just purchased a new toshiba laptop unfornatly it came with vista i need to put xp on it as i live in zimbabwe and vista is not compatable with most of the pc's here so i need to load xp but the laptop will not allow me to install any other operating system it tells me that either no hard drive is present or it is running a disk utility my question is this how to i bypass or disable this unility

i have tried formating the machine using the recovery cd but still no joy
