At the ADMIN Command Prompt type in or copy and paste :
sfc /scannow /offbootdir=c:\ /offwindir=c:\windows
If you are using any kind of boot image/disk to boot up, you will have to use the “offline” switches (OFFBOOTDIR & OFFWINDIR) along with the SFC /SCANNOW command in order to start repairing your instalation properly.
- please remember to tripple-check for corret partition letters, because this is a crucial parameter for SFC to start working properly.
- also make sure to confirm whether so called “recovery” partion exists in your specific scenario or not. If so, in most cases this will render the “recovery” partition being the one to be set as a boot partition (OFFBOOTDIR) within sfc command, while Windows system folder (OFFWINDIR) will actually reside on a different partition.
X:\sources>sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows
Beginning system scan. This process will take some time.
