At the windows setup screen. Press SHIFT + F10 to open command prompt.

1. At the command prompt, type: Diskpart.exe.
2. At the DISKPART prompt, type: Select Disk 1. (Provided is disk 1)
3. At the DISKPART prompt, type: CLEAN ALL (The CLEAN ALL command removes all partition and volume information from the hard drive
being focused on.)
4. At the DISKPART prompt, type: Exit.
5. Reboot computer to continue with the normal installation.

The steps should clear all the disk partition.

If you're not sure. Google diskpart for more info.
