ChkDsk Runs On Every StartUp.

If your chkdsk runs on every boot, here are some things you can try. First of all, let it run once completely.


Then try this :
Run regedit
Edit: HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\ Control\ Session Manager
Change the BootExecute entry from:
autocheck autochk * /.
autocheck autochk *


Or else try this :

Start> Run> bring up a command prompt by typing in “CMD” and type ” fsutil dirty query g: “. This queries the drive, and more than likely it will tell you that it is dirty. Next, type “CHKNTFS /X G:”. The X tells Windows to NOT check that particular drive (G) on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows.   Once Windows has fully loaded, bring up another CMD prompt and type and now you want to do a Chkdsk manually by typing “Chkdsk /f /r g:”. This should take you through 5 stages of the scan and will unset that dirty bit. Finally, type “fsutil dirty query g:” and Windows will confirm that the dirty bit is not set on that drive.


You can run the chkdsk /r command or the chkdsk /f command to check a hard disk for errors. But if The “chkdsk /r” command and the “chkdsk /f” command take a long time to run on a Windows Vista-based computer see this KB943974 Article.

  1. I had this problem but didn’t present itself as you would expect. The laptop has 2 partitions the first partition is the system recovery partition D: drive and the second partition is the system partition C: drive.

    Checkdisk would start at boot and start checking C:. When I used fsutil to check the partition it said it was not dirty. I found though when I checked the D: drive that it was the dirty drive. So it is worth checking all partitions on a disk when you have this problem not just the one that chkdsk is checking at start-up.
