Alienware X51 will not boot past the BIOS Screen.

My Alienware X51 crashed during the process of installing windows 10. While in recovery mode, I accidentally clicked "Use a Device" and now my computer will not boot up, It just keeps loading up the Bios screen. Every time the Bios screen loads up the computer beeps. I cannot even load up the windows recovery screen, please help!
