If you're certain OS X is present on that partition, you can use Gparted to flag it as the boot partition, this is the same as setting it as the active partition in windows.
in Gparted, right click the osx partition, select 'manage flags', check 'boot.'
i just noticed you mentioned cmd, i'm assuming then, that you're trying to do this in diskpart. try administrative tools instead:
control panel/ administrative tools / computer management / disk management tab.
this screenshot is from xp, but it's still present in win 7 and vista; though the path may be different.
just checked, and disk management won't do it either. the option to mark partition active is grayed out. but Gparted WILL do it.
while there is a standalone Gparted live available, i don't recommend it. create an UBUNTU live USB instead, and run it from that.
