Ubuntu does not load after installing it alongside Windows

view story

http://askubuntu.com – I installed ubuntu 12.04 and I chose to install 'alongside windows 7'. After installation and restart, Windows 7 loaded but there is no sign that Ubuntu is actually installed. Windows 7 is installed in hdd0, boots in legacy mode(Only 1 HD in machine), uefi secure boot is disabled. I don't see anything on uefi boot. My partitions on my 1TB HDD: 100MB ntfs (win 7 installtion made it automatically) 200GB NTFS (Win 7 partition) 4 GB Partition ( idk what file sys) rest all unallocated (HowTos)
