    ^^ If you have setup disc with you, try installing Windows 8.1 in a parallel drive. Once it is installed, you can backup all the data from main drive. If you wish you can use this newly installed OS, since it will also fix boot menu related issue.

  11. Hi,

    i did all the steps but it didn’t work.
    I have Win. 7

    After i did diskpart – it told me that all volumes are healthy.

    After doing chkdsk /r /f d: it said: “corrupt master file table. Windows cannot recover master file table. Failed to transfer logged message to the event log with status 50.”

    Please help.

    ^^ Try to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues – support.microsoft.com/kb/927392

  13. Hi, I have this problem on Windows 8. Until step 3 everything is correct and my RAW volume has assigned letter E:.

    When I type ‘chkdsk /r /f e:’ (step 4) I have message from system:
    ‘The type of the file system is RAW. CHKDSK is not available for RAW drives.’

    Do you know why step 4 doesn’t work on my PC?

    Please help :-) Thank you.
