Boot problem after installing with usb internet installation

I have installed opensuse using usb drive. I had windows and wubi based ubuntu.

I used unetbootin to make a boot usb.
After booting with the usb I format the hard drive and did a clean install.

The installation went perfectly fine but I can’t see the desktop when I switch on the computer.
I tried to boot again with usb and used the boot installed option. OpenSuse works fine once its booted.

Do I need the usb every time to boot? Is there a way I can configure opensuse to boot from harddrive? I restored the boot using YAST, but doesn’t seem to have and affect.

Thanks in advance
