To solve your problem, you need to get the Ubuntu installation disk you used to install Ubuntu on the USB and boot it up. Then, click on Try Ubuntu. When the desktop loads up, head over to the terminal and type in sudo apt-get install gparted gpart. If asked, hit y followed by return. Then, launch gparded with sudo gparted. After gparted loads, click on GParted on the top menubar, Devices, and the USB device you installed Ubuntu on. Then, unmount the partition by rightclicking on the partition and then hitting "Unmount". Then, right click again on the partition and click on "Manage Flags". Finally, click on the boot flag option and press close. The boot partition should now have the needed boot flag.
