how to boot from reformated installed hardrive

I just installed ubuntu on the hard drive reformatting the hard drive. I can still boot from a USB and I can see the hard drive was formated with the new OS.

when booting the computer will always come up no bootable device found (if I dont have the bootable USB drive installed)

I tried to disable the smart boot mode, no joy. How do I tell the bios that the HARD DRIVE is ok to boot from and to use the boot loader that is on the hard drive. I know it can do it because it would not be able to boot from the USB drive it it could not load the boot loader from the a device.
