I installed Ubuntu 12.04 (from a bootable USB) alongside my Windows Vista Ultimate operating system. Everything during installation went smoothly and at the end I got the message that Ubuntu is installed and I need to restart the computer which I did. However, when the computer restarts it automatically goes to Windows Vista and there is no option to load Ubuntu. Now the only sign of Ubuntu existing on my computer is that the hard drive size is 50gb smaller (which I allocated to Ubuntu during its installation). Can anyone please guide me what to change to bring the installed Ubuntu to life?
This problem is duplicate with no grub menu for 11.10 and 12.04LTS .
