That's either the hard disk that nees to be replaced or - of you're unlucky - the motherboard. With a non-working disk using the Windows install disk is impossible. You're right with that.
Hi Cnet community,
I am attempting to repair a friends laptop for my first time. I am currently taking an OS repair course right now, so I figured I might be able to fix the issue. His laptop will not boot. When starting the laptop, it stays on the loading windows screen. I ran a diagnostics test in the setup menu for the laptop. It said the hard disk failed. Ironically, I had a question on a quiz today that asked what should be done in this case. My answer was to replace the hard drive. The correct answer was to "boot laptop from Windows setup DVD". My friend no longer has the setup DVD, but regardless, don't I need to replace the hard drive? Won't that fix this problem?
