Option 1.
Yes, during Installation there will a page where you will be asked "which type of installation do you want" you should choose "Custom" from there you can format the partition where you will install the OS.
Option 2.
If you want to clean up the whole disk, you can try the Diskpart command.
- From inside Windows Setup, press Shift+F10 to open a command prompt window.
- Type diskpart and enter.
3..Type list disk .(look for your disk number, check the size of the disk)
- Type select disk <disk number>. example: select disk0 (select the disk you want to format)
- Type clean.

- Continue the Windows Setup installation.
I hope this helps. Feel free to ask back any questions and keep me posted.
