[marcustcicero]

My Hp envy laptop (Windows 7) says no bootable device. Insert disk; i never had a disk. Can anyone help?

So you dont have a hard disc?

If you turn on your HP press ESC button then F9 and choose your hard drive.

Is this a new condition?
What was the last thing you did before this happened?
