Hello again Boggin!
Apologies for the delay in getting back to you; the wedding went well but a member of my party was taken to ED the next morning with suspected heart attack, which ended up being a massive hiatus hernia, and I had to stay nearby to support and take home when discharged. Upshot being I didn't return home until yesterday.
So having already prepared to follow process, I proceeded to create the Win 7 install disk; all good!
Then F12 while booting, but wrong options came up ie just the boot order.
Restarted and tried F8 as sure that's where I'd seen Repair your Computer option, and it was. Inserted disc, selected Command prompt & entered first instruction, then entered sfc instruction, and off it went.
Sadly, it returned the exact same message as previously ie Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log. I accessed the log and saved file.
Removed disc, rebooted and performed another sfc /scannow as instructed, from Command prompt with Admin', in normal not safe mode.
Again, it returned the same message, and when I tried to bring up the log file, it advised 'The process cannot access the file because it is being used by another process.'
Rebooted again, and successfully accessed log file.
Hoped it would send as attachment this time, as previously wouldn't, but no such luck :-(
Await further instruction and thank you for your time.
Cate
