You're trying to update your Win 7 system from a flash drive?  I have no clue what's on it, but if it's something you can install Windows from, it should look close enough to a DVD or an ISO to be usable.  Try rebooting, with your BIOS pointing to the flash drive as your primary drive, then tell Windows you want to repair your system.  Alternately, use DemonTools or some other tool to make an ISO image of that flash unit on your hard drive, and point your SFC program at the virtual disk.

No - not trying to update Win 7 system from a flash drive (I don't think).


When SFCFix.exe attempts to fix an issue it might want to look for files on the Windows installation CD/DVD and it might only know about CD/DVD drives and not flash drives.


You might want to clean things up a little by navigating to this folder and deleting all the files in it (assuming Windows is installed on your C drive):




Now run sfc  /scannow again which will create a fresh log file with only the most recent events.


See what SFCFix.exe has to say now.


If I had an SFC problem that SFCFix could not repair and I could not fix it myself I would look at these generic instruction (some of which you have already done):




Depending on what has happened to your system the fix could be very easy or you might need some help so I would downloading SFCFix.exe to your desktop from this link:




For testing, learning and practice purposes it is easy to create corruption issues that cannot be fixed by sfc  /scannow.


First I manually created a problem that sfc /scannow reported but could not fix (SFC is not as smart as some folks think) then ran SFCFix.exe to see what it had to say.


Sometimes the SFCFix.exe process will fix the problem all by itself as you can see in this simple example where I created a corruption that sfc /scannow could not fix but SFCFix.exe was able to fix an "unimportant" corruption in one pass:

SFCFix.exe fixed one corruption all by itself:



When I ran sfc /scannow again the problem I created was fixed and running sfc /scannow again reported no issues.



That was pretty easy.


If SFCFix.exe can't fix the problem you may be promoted to insert your genuine Windows 7 SP1 installation CD/DVD and SFCFix will try to get the missing file(s) from there but if you don't have that or SFCFix can't find what it needs a results and log file called SFCFix.txt will be created on your desktop:



If SFCFix.exe can't fix the problem you then register a new account at Sysnative, follow the directions and they will send you back a ZIP file with the fixes for you to apply.  Often you get the fix in one message cycle because they know what they are doing.  It might take a little more depending on what is wrong.


Be sure to read, understand and follow their directions exactly:




Following the directions will get you the fastest and best reply in the fewest message cycles.


For simple cases what usually happens is they will analyze the report (may ask for more details) and eventually send you some instructions and a ZIP file that has in it the files you need to correct the problem and you are done.


Sometimes the problems are more complicated but eventually they should help get things squared away.


Be a mench and come back and tell us how it goes!
