#1: Common tool: SFC scannow

Before trying the SFC scannow server 2012 r2, we need to get a clear understanding of this tool. The SFC is “System File Detection” program, used under a command prompt. Besides, only the one with administrator rights can open and run this program. It is able to scan your Windows system files for corruption or any other changes. If a protected file has been detected to be covered by a wrong file, the SFC will automatically extract the correct file from the system backup to replace the incorrect version.

1) Put the Windows Server 2012 R2 installation disk into the CD drive, and then start the computer.

2) When the message “press any key to start from CD or DVD” shows up, press a key and Windows Setup screen will pop out.

3) Select language to install, time and currency format, keyboard or input methods, and click “Next”.

4) Hit “Repair your computer”.

5) Click the operating system you want to repair and click “Next”.

6)  In the System Recovery Options dialog box, click “Command prompt”.

7) Type “SFC/scannow” in the command window and press Enter.

Then, the system will automatically scan the integrity of all protected system files and repair the incorrect one by itself. It will take about 5 minutes, so please be patient.

In addition to using the SFC command, you can also check and fix the system boot record, which can also be done in the command prompt window. You just need to input the following commands in turn and press enter after each:

bootrec / fixmbr

bootrec / fixboot

After the scanning and repair process is finished, you can restart your computer and enter the desktop successfully.
