I have just now install Windows 7. Perior to this I was having Windows 7 and Ubuntu both installed side by sides (Ubuntu was installed after the Windows). But after installing windows, there is no boot menu to boot into Ubuntu.

I don't want to reinstall Ubuntu. What & How to configure to again boot in into Ubuntu?

The easy way
EasyBCD - Take control of your boot loader | NeoSmart Technologies

The hard way (but preferable to me) would be to reinstall grub through a LiveCD.

Use these commands in linux---

sudo update-grub

sudo mount /dev/sda1 /mnt
sudo grub-install --root-directory=/mnt /dev/sda
sudo grub-install --boot-directory=/mnt/boot /dev/sda

EasyBCD didn't worked, I tried following:
1. Configured EasyBCD at auto mode, but it shows something else than boot menu.
2. Also I tried setting up another Ubuntu option to get the Ubuntu at the boot menu but when I select Ubuntu at the boot menu then it restarts and this loop goes on.

3. I tried the grub method, it gives an error are you sure /dev is mounted?


At last I backed up my home directory and installed it freshly.. ...was pretty simple than those above.

This is what i did the last time i had to add Ubuntu to the windows boot list.

1.Click 'Add New Entry '.
2.Select 'Linux/BSD' tab under Operating Systems.
3.Select 'Type' as 'GRUB(Legacy)'.
4.Change the name if you want.
5.Select the Linux partition as 'Device'.
6.Check 'Use EasyBCD's copy of GRUB'.
7.Click 'Add Entry'.
