With a lot of help from Ask Ubuntu, I have successfully installed 12.10 onto an HP Pavilion g6 2240sa notebook to create a dual boot machine which also has Win8. This could only be achieved by a full BIOS/GRUB installation (not WUBI). If I press Esc on boot up I can get into BIOS, access GRUB2.00 and select Ubuntu. If I do not access BIOS on start up the machine runs straight through to WIN8 making Ubuntu inaccessible. I want to switch the machine on and have it boot through to a menu offering Ubuntu 12.10 as first choice without forcing Win8 on me. How do I do this?

How can I ensure that I boot to an OS option menu (default preference Ubuntu - of course!) when I switch the machine on? Here are my installation details
