I have an XC-603G Acer Aspire from Walmart. I cannot get it to upgrade to Windows 10 because

__the upgrade app insists on installing all missing updates to the Windows 8.1 which are installed at the

__factory. It gets to within 2% of finishing, claims that it failed, and then undoes everything that it

__just did. Total time lost: 6 hours.

 

Someone suggested running "sfc /scannow" to repair possible system file damage.

 

Here is a sample of 3 of the errors that it found:

                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 PublicKey is neutral in the store, hash mismatch

 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It's claiming that the "store" (the back-up data to use for correction) contains corrupted data itself!

 

Where do I go from here?

 

Thanks

    Run, as Administrator,  chkdsk /f

    See what that says and then run chkdsk /f /r and see how many bad sectors you have.
