Sounds like grub has been installed to the usb. From your booted Ubuntu system, open a terminal, then use the following commands to install grub to the internal drive :

sudo grub-install /dev/sdX
sudo update-grub

Replacing sdX with the actual drive, which will probably be sda, but use disk utility to double check if you are unsure.

Accidently installed grub to usb

  • Boot-repair is a good resource. If you're not using EFI sometimes Ubuntu installs an EFI grub loader (grub-common) your computer might only support bios boot loading which is grub-pc. – Randnum Jul 08 '12 at 18:03
