Yesterday I installed Ubuntu 12.04.1 64bit in my laptop with windows 7. The installation was dual. I did the required partition and kept a free space for linux. I gave the appropriate space for swap area and ext4. Ubuntu got installed well. Then finally after installation, I was asked to reboot my system.

While rebooting, as we expect, the system should ask me whether I want to start windows or linux. But it did'nt ask me any of it. The system directly takes me to windows without giving me any option for linux. I tried restarting again, but i was directly taken to windows. Can you help me know this ? Did i go wrong somewhere with my installation? How can i correct it and get to linux ?

Thanks in advance..

I thank you for your reply. I am not sure in which partition did I install my grub. Honestly this is really new to me. I am trying to follow the instructions mentioned in the link you provided. It is really a clear description on how to install ubuntu step by step. But however, I am stuck at using the "EasyBCD" tool. I have tried installing several times, but after installing, when I try to run it, it gives me an error saying,

"error Opening BCD Registry"

I have attached the image as well. Could you give me an alternative ? Or any way to resolve that?

It seems that GRUB was not installed on the MBR.

Follow these steps:

  • Boot using a LiveUSB.

  • Open a terminal. Run the following commands:

    sudo grub-install /dev/sda
    sudo update-grub
  • Reboot.

In which partition did you install grub? If you didn't installed it on the same partition as Windows 7, then the default partition to boot will remain the Windows 7.

An easy way to fix this is to use EasyBCD to add ubuntu to Windows 7 boot entry menu. This link should help you: dual boot ubuntu 12.04 and windows 7
