Esta é a resolução sugerida:
Inicialize o disco do Windows 7.
When the welcome screen comes up on Windows Setup, press Shift + F10, which will display a command prompt.
Type diskpart and press enter.
Type list disk and press enter.
Hopefully you can see your SSD in the list. You should see a number identifying it. Now type select disk X (where X is the number identifying your SSD) and press enter.
Type clean and press enter. This will write a blank MBR, YOU WILL LOSE ANY DATA ON THE SSD if you did have anything on it.
