Ubuntu not getting installed

Question

I downloaded ubuntu 12.04 lts 64bit version. Laptop already has windows 7 and installed along side windows 7. After installation, it is not showing up in boot menu. Instead it is directly booting to windows 7. Laptop supports 64 bit. I did the same thing in my pc, but it worked fine. Also after installation, in windows 7, the ext4 partition doesn't show up. Please help. Thank You

Answer 1

ext4 partitions will not be shown/mounted under Windows.

Ubuntu can be added to Windows bootloader by using a simple easy-to-use software EasyBCD.

Please follow the instructions provided by EasyBCD creators here.

Steps 5-7 can be omitted if you want to see GRUB for about 10 seconds. This might be useful if you want to boot into a different kernel for Ubuntu.

Download EasyBCD without registering in their website by following this link.

Disclaimer: Keep in mind, this will enable windows bootloader by default, not GRUB. If you want to keep GRUB as default bootmanager, follow the tutorial mentioned by @m-tarun.
