ubuntu partition not recognized by plop

[manos]

I have a windows 7 / ubuntu 14 installation. Windows 7 installed in partition2 and ubuntu installed in partition3. Plop bootloader is installed in partition 1 and boots normally in windows 7. Ubuntu is installed in partition 2 and boots only via live cd or hiren's boot disc.

How can i add a secont profile to plop so i can boot Ubuntu through plop.
