My pc - Dell Vostro 3670.

I added 256GB ssd and 8Gb RAM. Then I have tried to install windows 10 using DVD. But in boot sequence there is no option of cd/dvd drive. Then I tried various ways suggested from dell community or youtube, but those doesn't work for me. 

As per their suggestion, I follow press F2>BIOS setup>General>Boot Sequence. Then I select UEFI in boot option and then press on Add Boot Option button. Then I got a "Warning" message 'File System Not Found!' But as per suggestions, I should have different window rather then this "Warning" window.

Note: My hard disk is empty. There is no OS.

PLEASE, HELP.
