Every time I turn on my PC, I get the following message:

Checking file system on E:
The type of the file systen is NTFS.
One of your disks need to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue.
Windows will now check the disk.

CHKDSK is verifying files (stage 1 of 3)... 0 percent completed

I allow CHKDSK to to complete, but Windows does not load. This message appears every time I boot my computer.

Could someone explain me why this message appears and what I should do to make it disappear?

    @hims056 That question refers to a system that is working. The OP has stated that chkdsk completes but Windows does not load.

When you schedule a check disk, an entry is added to the registry - for some reason, it's not being cleared.

  1. Run the Registry Editor (Click Start, Run and type regedit then press OK).
  2. Locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
  3. Change the BootExecute entry from:
    autocheck autochk * /r\DosDevice\C:
    autocheck autochk *

  • I go step by step in those article, but in my Registry Editor BootExecute already has value autocheck autochk * not like autochk * /r\DosDevice\C:

  • If the CHKDSK were scheduled, I believe the message would say that. This seems to be a problem with the HDD itself, rather than a scheduled disk check not being cleared.

  • Yes, it does. In that case, I would suggest checking it with acronis.co.uk/homecomputing/products/drive-monitor

If you have not asked for a chkdsk to be carried out, the autocheck will be carried out if the disk's "dirty bit" is set. This will be set if Windows is not shut down correctly, file changes have not completed or the disk is corrupted. It may indicate the disk is about to fail. For an external disk, it may indicate it was removed without using the 'safely remove hardware' function.

The fsutil command can be used to check the status of the dirty bit. Open a command prompt with admin rights and type:

fsutil dirty query D:

(Replace D: with the letter of the drive you are having issues with.)

    I check my hard disk, it is dirty - what should I do to correct this?

    Try running chkdsk /f e: or chkdsk /f /r e: manually. If the dirty bit is still set after the next reboot, the system probably cannot umount the volume on shutdown. Check the eventlog for pointers if that's the case Commented Sep 3, 2012 at 14:27
  • I get such message after executing command chkdsk /f e: E:\Documents and Settings\Consultant>chkdsk /f /r e: The type of the file system is NTFS. Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N) n

    @khris That's normal. You can only run chkdsk on the system drive at boot. Commented Sep 3, 2012 at 15:36
  • ok, I try once again: 1) enter chkd /f /r in cmd 2) press y after message that drive can't be locked 3)restart my pc - the same message (as in my parent question) 4) allowfile verifying. In result I get message thet verifying is complite on blue screen and windows do nnot load and I can't execute any command - just shut down os pressing button on keyboard.

  1. Click on your start menu and open the run dialog.
  2. Type cmd and return
  3. Next type fsutil dirty query D: (replace D: with your drive letter)

fsutil dirty query

If the return message indicates that the volume is dirty then continue with these steps:

  1. Next type chkdsk D: /f /x
  2. After that finshes repeat step 3 to determine if dirty bit has been removed.
  3. If it is no longer dirty then reboot and you should notice no more chkdisk.

I had similar symptoms on my laptop as you and:

chkntfs /X E:

Helped me (I didn't expect this).

Also try change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager key BootExecute to:

autocheck autochk /k:E *

A cause example:
In my case, Check-disk (at boot) is (re)produced from a "bad" misconfigurated custom shutdown batch|command, which (accidentally) makes the system thinks the shutdown was "Unexpected" (not normaly shutted) and sets the disk-check . - IF the "dirty" disk is the windows disk(C:) must be dismounted first - but, as the disk is in use by the system, sets an auto chkdsk at the next boot.

Cause more explanation:
I have set a "Run-on-idle-time" 'scheduled task' which after (1hour) pointed idle time expiration, triggers a custom HurryCleanNShutDown.bat|cmd program. So, the program eg. starts the 'cleans', waits to finish and then shuts down (forced) the Computer. Even if I tried many shutdown switch(es) (/d) combinations (SHUTDOWN.exe /s /t 60 /f /d p:0:0 /c "PC shutting down... (in 1 minute)" or even with chkNTFS /x c:) the computer keeps giving the same problem Only IF Shutting Down triggered by this batch|program.

Note that if any third program could not use proper shutdown command syntax could reason this false chkDSK error.

Use of ShutDown: (shutdown /?)
- If shutdown is not accompanied by the required /d'switch' with the p|u:xx:yy 'reason code', then the system considers this 'Shutdown'shutdown /s (or 'Reboot'shutdown /r) as "Unexpected" (not normaly shutted).
- If the above happens, the system points|flags the disc as "dirty" (bit) in the registry and promts for disk-check or (if it's current System's drive[C:] in use), sets an auto chkdsk (chkDSK C: /f ... /x) at the next boot (because System drive must dismount first).
- After successful "chkDSK" the System will return to normal chkNTFS /d ---> [RegEdit: BootExecute value data: "autocheck autochk *"].


Suggested to use the "Command Prompt" (run as admin) instead of "Registry Editor".
It is much easier to use chkNTFS command which automatically changes the
---> "BootExecute REG_MULTI_SZ" data value. (examples following below)

Also, if computer do not boot,
chkDSK and chkNTFS commands can be run from Recovery Console too.
/!\ Warning: command 'switches' differs a bit when you run from Recovery.
Tip: chkntfs /? | chkdsk /? to saw the use of.

  • How to Forced Check Disk on (E:) disk:
    chkNTFS /c E: ("E:" is disk letter)
    ---> [RegEdit: BootExecute value data: "autocheck autochk /m ??\E:"]

    chkNTFS /x c: ("c:" is disk letter)

  • How to Restore Defaults: (Restores the machine to the default behavior:
    all drives are checked at boot time and chkdsk is run on those that are dirty.)
