I have a HP desktop that was ravaged with viruses and the HP recovery parttion was destroyed. I have treid to Load XP pro on the machine that was running XP home. Using the installtion CD I am unable to "break" the partition and reformat it to NTFS so i can install a clean version on the drive. I have tried using the ARS (automatic recovery service) and that will not allow me to format the drive eitehr. Does anyone have any ideas how to destroy that partition so i may install a clean copy?
