Cannot boot after installing alongside Win7

[ErsinG]

Today I tried to install Ubuntu 11.10 x64 to my Sony Vaio F13 series.

The problem is, Windows is installed to the C: drive of my computer. However, when I choose to install Ubuntu alongside Windows 7, ubuntu recommended me to install to D: drive.

After I installed Ubuntu, there is no option to boot in Ubuntu. It just boots into Windows 7 which I do not want to.

How can i fix this problem?

Do you use the Wubi.exe installation on Windows?

No I installed using Ubuntu 10.10 CD

After doing another try, my issue resolved.

Now Grub properly shows up and let me select the operating system I want to boot in.
