Hi. My DVD drive was not reading any of the discs that I've put in. I have restarted a lot of times but the problem still persisted. I go to My Computer to open the drive from there but it ends up not responding to the point when my laptop froze. I had to turn the power off when this happened because I couldn't reboot the proper way. This was the screen when my laptop was turned back on. FIRST SCREEN Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart 2. Choose language.. 3. Click "repair your computer" If you do not have the disc, contact your system administraton... File:\Windows\system32\config\system Status: 0xc000000e9 Info: Windows failed to load because the system registry file is mmissing, corrupt. I press ENTER and this comes up: SECOND SCREEN Choose an operating system to start, or press TAB to select a tool: Microsoft Windows Vista (this is highlighted) To specify an advance option for this choice, press F8 Tools: Windows Memory Diagnostic I choose the highlighted option and this comes up: THIRD SCREEN Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart 2. Choose language.. 3. Click "repair your computer" Other options: If power was interrupted during startup, choose start windows normally Safe mode Safe mode with networking Safe mode with COmmand prompt Last known good configuration (advanced) Satrt windows normally (this is highlighted) Every time I choose ENTER or any of the highlighted options it jsut goes back to any of the 3 screens above. I tried my installation disc but my DVD driver does not work. Would really appreciate all help and suggestions. Thanks!!!
