My Disk Manager:

  1. I installed XP on the first partition. (Drive D)
  2. I installed Windows 7 (64 bit) on the second partition. (Drive C)
  3. I installed EasyBCD 2.2 on the Windows 7

At this point my daul boot between XP and Windows 7 is just fine.

I then installed Ubuntu 13 (64 bit) on the 4th partition (78.13GB), I formatted the partition using Ubuntu Installer (ext4, with swap of 6GB), the installation was successful (I think)

After the installation of Ubuntu, there is no change to my the boot screen, I have no way to boot into Ubuntu, so I tried to edit using EasyBCD again.

... I tried to follow the EasyBCD documentation.

I now can see the boot menu for booting into Ubuntu but after choosing it, I got this.

My suggestion is to reinstall the grub from a ubuntu liveCD:

(i) boot to a live ubuntu, (ii) open a terminal (iii) type the following command:

sudo fdisk -l
sudo mount /dev/sdaX /mnt #where X is your ubuntu ext4 /(read root) partition
sudo grub-install --root-directory=/mnt /dev/sda

after these steps if no error accoured you can reboot and everything should be fine. at least you should be able to log into your ubuntu. and if you are not seeing other OSes in grub menu type the following command in ubuntu (from your installed one. not in live mode)

sudo update-grub

This should solved your problem unless you have a UEFI problem. If you have one you may need more steps.

By the way for Ubuntu specific question you can use askubuntu.
