Computer Problems After Power Failure I have a Dell Dimension Desktop. The other day our power suddenly went off and when the power came back on my computer would not work. A Blue Screen appears when Windows is trying to open and states, “Unmountable_Boot_Volume,” I have tried to load Windows in Safe Mode and everything- nothing works. So, I downloaded startup disks from Microsoft so I could repair windows, but once I get to the screen in Setup after hitting “r” it states, “Did not find hard disk drives installed.” Does anyone know how I might fix this??? THANK YOU!
