Yes, those partitions sda1,2,3 are the ones originally used. The ubuntu
installer
has overwritten sda even it was told to use sdb in the second install where I
wanted to install to usb disk. If you take ubuntu manual install which I didnt,
you are
asked  where to install grub. Next time I will for sure use it that way.
 
Thank you.
