Description

I recently had a Windows 7 machine start acting up (in the usual Windows way). After running a sfc /scannow the output only stated that it has found corrupted files that Windows could not fix.

To resolve this I booted off of a Windows 7 install disc, entered a recovery prompt, and ran an offline chkdsk.

Offline chkdsk

  1. Boot from Windows 7 DVD.
  2. Select a language.
  3. Select Repair Your Computer.
  4. Choose your target system, in my case Windows 7.
  5. In the recovery tool panel, choose Command Prompt.
  6. Run chkdsk:
    chkdsk C: /F /R

Offline sfc

  1. Boot from Windows 7 DVD.
  2. Select a language.
  3. Select Repair Your Computer.
  4. Choose your target system, in my case Windows 7.
  5. In the recovery tool panel, choose Command Prompt.
  6. Run sfc:
    sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
