Actually the question says it all, but let me tell you what I did, so u may find exactly what might have went wrong:
I have Win 8 installed on 500 GB HDD.
SO I shrunk it four times for:
partition 1 - the original partition containing Win 8 sys (118GB)
partition 2 - NTFS formatted for my data (188GB)
partition 3 - NTFS formatted for my data (100GB)
partition 4 - NTFS formatted for Linux distro 1 (I reformatted it to ext4 during Ubuntu installation) (25GB)
partition 5 - NTFS formatted for Linux distro 1 (21GB)
So now I booted Ubuntu from USB (created from ubuntu-12.04-desktop-amd64.iso) and
deleted last two partitions 4 and 5 to create:
partition 1 - ext4 where I installed Ubuntu (25GB)
partition 2 - Swap (4GB)
partition 3 - unallocated space, not formatted yet (17GB)
Ubuntu installation said it installed successfully and that I have to restart to boot in Ubuntu. But when I restart Windows 8 auto booted - there was no dual boot.
After that I devided above 100GB partition to 80Gb and 20GB ones (since I read online that I should have /home in separate partition for convenience, so I created 20GB partition for it)
So I went on to manually create boot entry using EasyBCD as below show in picture at below link

When I created the entry, FreeBCD showed the information as follows:

Notice the last bolded entry created.
Howevever after thet, when I rebooted it firstly showed old DOS like bootloader (no Windows 8 UI based bootloader) with two entries Windows and Ubuntu.
Windows 8 was booting correctly but I was getting an error while booting Ubuntu taking me to GRUB Rescue.
Please help am new to Linux world.
