I have a HP DV4-1028US notebook, it has HP recovery partition. The notebook is pre-installed a Vista home Premium. I reinstalled the OS with Vista Ultimate. After that I installed Acronis Disk Direct to format the HP recovery partition to free up some space. Then I installed Acronis True Image and activated acronize Zone. When booting the notebook I can see Acronis's prompt to "presss F11 to enter acronis.....". I pressed F11, but it's didn't enter acronis, it directly entered the Vista. How to fix this problem?
