Reformatting two drives before re-installation.

I'm new to Linux generally. Can someone give me instructions on formatting the hard drives?

I have installed ubuntu on a machine that had been running Windows for a while. Since Windows worked the boot drive for years, I decided to switch the positions of the two drives; putting the old data drive into the boot position.

Apparently, ubunta was too smart for me. I guess it discovered the Windows installation, and decided that's where it should be installed too. Now, what I would like to do - and I would really like to do it this way - is reformat both the disks, wiping out everything that's on both of them; before running another installation.

BTW: the old data drive is still NTFS, and I don't want installations own both disks - reformatting and starting fresh seems nice and clean, if not entirely necessary.

what you need:

use gparted or partedmagic to create 3 partitions:
- / : root, bootable, ext4, ~ 12 Gb (take note of its name: /dev/sd? , will be asked when installing in manual mode by the "alternate" iso.
- swap : about 2 Gb (4 Gb if suspend/hibernation is used)
- /home : ext3 or ext4 format, unlimited space to store your data and settings
