I have Vista Home Premium installed on my laptop. I am trying to install Ubuntu 7.10 to have a dual boot. I have followed the Ubuntu installation guide on this site. However, when I get to step 4 - click the advanced button - there is no advanced button. The installation setup goes straight from editing partitions to user setups. I have tried going ahead anyway but Ubuntu writes over the Vista bootloader in the MBR. Any help in how to prevent this would be very welcome.
