Unable to boot into Ubuntu after fresh installation

In my laptop (Lenovo Ideapad v570), which came with 750GB HDD with 4 NTFS primary partitions I installed ubuntu by following these steps

The 4 partions were, 1.(650GB)Windows7 2. (30GB) Lenovo/Drivers 3.System 210 MB 4. (16GB)Recovery

I shrunk the windows drive to 245GB, by using disk management in windows 7 and created unallocated free space of ~450GB

Using ubuntu live cd , I installed ubuntu 11.10 by selecting the option Ïnstall along side windows

Ubuntu 11.10 was installed without any error.

But on reboot, the boot menu does not appear and system boots into Windows 7 . I checked again using ubuntu live cd, and ubuntu is actually installed on the harddrive. (I could browse the files)

The ubuntu disk utility output is as shown below.

As can be seen in the screenshot, there is a warning that says, "Partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested". Does this warning has anything to do with the problem?

I have encountered the misaligned partition warning before and it never effected the system booting. More than likely the reason your system is booting straight into Windows 7 and not prompting you is because Ubuntu wasn't added to the MBR. If you are comfortable editing your MBR then log into Windows and do so. If you are not that comfortable doing so, I would suggest a program called EasyBCD. EasyBCD is a program that gives you a GUI to edit your MBR, and it is incredibly easy to use.
