Answer 1

Warning! This will erase EVERYTHING on your internal HDD

1. Inside the Windows installer, at the welcome screen (before the partitioning screen) hit Shift+F10.

2. At the command prompt, type diskpart

3. Once diskpart loads, (it will take a few seconds) type:

    list disk
   

4. Take note of the number assigned to your internal HDD

5. Then, run this command, replacing X with the number assigned to your internal HDD:

    select disk X
   

6. Finally, do:

    clean

Then, close both CMD Windows and proceed with the install.
