I recently bought a lap top with windows 8.1 already installed . I installed Ubuntu om my lap by creating free space using windows disk manager. i successfully installed ubuntu. But after restarting it does not show any boot menu to boot in to ubuntu. it directly entering to windows.
My laptop is HP-r014-tx
The person who marked my question as duplicate please understand in that question his problem is different. He cant boot windows.. My problem is just reverese :(
