That would be caused by installing the boot loader (Grub2) to the MBR during the Ubuntu install, which is the default action for the Ubuntu installer. To avoid this, you need to tell the installer to install Grub2 to the Ubuntu root partition instead . This is covered in the Ubuntu install procedure in this KB article (see step 19):http://www.terabyteunlimited.com/kb/article.php?id=279

Since you just installed, the easiest would be to just reinstall Ubuntu by following the procedure in the KB article linked above. While it's more tedious to do, you can also fix the problem by manually reinstalling Grub2, as covered in this KB article:http://www.terabyteunlimited.com/kb/article.php?id=408
