Default Don't have HBOOT in menu


I want to unlock HTC Desire with HTC Sim unlock utility which I found here on xda, but I have a problem.

I think that I don't have correct drivers for hboot on my PC so I searched a internet and found some solution. Problem is that when I boot phone with vol down + power combination I can't enter hboot menu, there is only 4 options and neither of them are hboot.

Which steps should I take?

Thank you.
