Original title: wdfilter.sys missing or contains error.

Ok so after I got WdBoot.sys error, I did  chkdsk and sfc /scannow. It seems to go away, but another Wd error appears again, WdFilter.sys now. It seems that windows defender is having problem but I don't know how that happens. I'm also assuming the whole wd driver is faulty. Any solution?

Update: I just did a system restore and the wdboot.sys error came back.

Hello, I’m Virginia an independent advisor with 20 years of expertise in fixing my own & friends’ PC problems.

Which Windows 10 build are you running - 1909, 2004, 20H2 or 21H1?

The problem can be caused by malware:

Try running these programs:

MBAM free: https://www.malwarebytes.com/mwb-download/

Eset online scanner: http://www.eset.com/us/online-scanner/

Adwcleaner: https://www.malwarebytes.com/adwcleaner/

If these find one or more infections but do not fully remove them it will be wise to register with a malware removal site to receive dedicated malware removal instructions, an expert will remain with you throughout the process until confirmation that your PC is 100% clean.

    I've tried fixmbr and fixboot. It said successfully. But for scanos and rebuildbcd said Total windows installed: 0.

    Yes that.

    Also to be clear, the problem occurred after I decided to system restore. I assume the system restore is corrupted. I'm also thinking to use a bootable USB from my friend but how do I do this?

    You would need to run these cmds:

    bootrec /fixmbr

    bootrec /fixboot

    bootrec /scanos

    bootrec /rebuildbcd

    However as you’ve already done these & it hasn’t fixed the problem then the only option is to clean install Windows.

    Is the error: The Selected Disk Is Not a Fixed MBR Disk or something else?
