My Windows 7 machine failed to load after a start up repair failed.

The error message I got was this:

Root cause found:
A patch is preventing the system from starting
Error code = 0x1F

Does anyone know how I can fix this?

Tony, I would bet that giving your question a much better, more descriptive title will result in more people willing to help you out. – Brian Wigginton Jan 22 '11 at 6:00

Based on your error it sounds like a Windows Update has been applied incorrectly. Your only real hope if you are not a technically savvy person is to run system restore on your computer. You can do so from the Start up repair utility.
