I had trouble booting from certain rescue disks. I have Win8.1 upgrade from Win8 now. Since then I have had several issues to work out. I thought my backups were working properly, but they are not. I looked at event viewer for File History. Come to find out I had a problem come up there. It said: I checked the File History log in Event Viewer, and each hour I get the following Warning: Unusual condition was encountered during scanning user libraries for changes and performing backup of modified files for configuration C:\Users\Me\AppData\Local\Microsoft\Windows\FileHistory\Configuration\Config So then I see in another forum about running SFC /scannow to fix corrupted files. Well I did that, but it did not fix them all. (yes I rebooted after that) So now I have a CBS log, but cannot make heads or tails of that. I will post it last. Why can't Microsoft let you do a scan, and download missing, or corrupt files, straight from their website? I wish they would at least consider it. So, am I going to have to try to use the cd I burned to somehow get these files? I don't see a safe mode for Win8.1, and I am feeling like I'm in over my head on this. If my one allowed copy is messed up, I am going to be up a creek. I bought this computer the first few days of Jan 2013. Everything was fine until I went to Win8.1 via the store. It has been a headache ever since. I did make a boot copy from Macrium Reflect. It does work. But neither the ESET SysRescue, or the Kaspersky 10 boot. Now I guess I know why, my files are corrupted. I made an ISO via Macrium Reflect, as it had trouble making the WinPe for the boot. Any suggestions? I will post the CBS log if that could help anyone figure this out. Otherwise I may have to start over. That would be a major pain, and many days worth of work. I had File History back ups, or so I thought. So now, the only thing I know I have backed up is my documents, and photos. Those are on a usb flash, as well as My Passport. I would sure appreciate a way to get out of this mess, without starting from scratch. I uploaded the file, for anyone that might be able to see what is wrong. It was too long to post on the text of this thread. So I had to upload it. I decided to use the Tweaking.com Windows Repair program, and I'm going to do another SFC /scannow and see what it says this time. Oh, and before this the Check Disk scan was good, with no issues. Well, it still says I have corrupted files, so that didn't fix it.
