Guys, I think I have deleted my computer from it's own memory if that is possible. After a virus fix and a system restore I was checking file sharing and network and I think I deleted the computer I was using from it's own network?????? Now just booting to a blank screen with flashing cursor, constant speed with no code sequence etc. Only get option of F2 and F12 (setup and boot order) which I have altered to no effect. Now back to normal boot setup and at a loss for a fix. Thinking of getting Windows on a USB and booting from there but is there another way without losing everything?
