The simple way would be delete all the partitions on both the hard disks, create a new partitions and install the OS on the first partition of the first hard disks...

How do you delete the partitions

Insert the Vista DVD in the DVD Rom and then boot from the Vista DVD, Once you get to the installation screen after files have been loaded, you will reach a screen where you have to select a partition to install Windows on. Then select one partition and then click on 'Drive Option' on the right-bottom side. Now some new options will appear there, from there select delete the partition. Similarly do for all partition. Now once all the partitions are deleted, you will see only one partition there. Click on it and select New partition. Then enter the size and then again create new parition. Do this to create paritions of your choice.
