You turn on your computer and instead of it booting up to Windows you get a message like "No operating system found..." or "Ntldr is missing..." These messages indicate that your operating system has been corrupted and will not run. If your computer starts but is very slow and makes a lot of clicking sounds, your hard drive may be failing.
I can fix operating system problems and get your computer running again, and in many instances save your data and settings. Hard drives can be replaced and data and settings recovered if the mechanics of the drive are not too damaged. I will do all of this at your location and at your convenience.
