Windows 7 SP1 fails with error 800B0100

I have an issue (like many others on here) where Windows 7 SP1 won't install and gives the error 800B0100. I've run the usual troubleshooter and System update readiness tool with no joy. The CheckSUR log file shows 10 errors and I've uploaded a copy of the log with this post. Hoping someone can help me avoid having to do a Windows repair install :-) Thanks in advance Mike
