I installed windows 10 on my Dell inspiron 4320 laptop through USB. My laptop doesn't read any cds and DVD. After installing wnd 10 I reset computer to factory but it tooked too long and battery gone dead so it can't get completed. But a while after I connect it to the main and tried to open it but it says operating system not found every time I start it. If there who could help please help me through effective reply please.
