Can you change hard disk partition sizes during a fresh (clean) Vista installation?
yeah ,when the installation asks you when do you want to install windows ,you will see all the partitions on your pc and their sizes ,click on more options (on the right side of the screen) ,now you can delete a partition and format one and make a new one ,you will lose all data in the partition when you delete it ,to change a size of it you will need to delete is and and then make a new one .
