It looks like the Ubuntu install did write the GRUB into the MBR of the 
ATA Disk, but your BIOS boots the SATA. Hence, windows is booting. You 
have to install GRUB into the MBR of your SATA. Sorry, I don't know how, 
but you could boot from the live cd and chroot into the Ubuntu install. 
Use grub-install and tell to install into the MBR of the SATA disk.
Just, google a bit on reinstalling GRUB from a live CD and read the man 
pages of GRUB.

Hope this helps, Thomas
