Vista - Chkdsk will Not Run at Startup in Vista

Information

If after you set Check Disk or chkdsk to run at startup it will not run, then this will show you how to fix this problem so chkdsk will run at startup. This problem is usually caused when the autochk.exe file gets corrupted, or the registry BootExecute data value is incorrect. This is not for if chkdsk cannot finish or stops running.

NOTE

Check Disk uses the file autochk.exe to run chkdsk. If you still cannot run chkdsk at startup after this, then you might consider performing a System Restore, Repair Installation, or Clean Installation to fix the problem. See related links below. If you had changed your default boot screen, then you will need to temporarily uncheck the No GUI boot to be able to see what is happening when chkdsk is running at boot up.

NOTE

This is to see if something may be loading before the check disk program preventing chkdsk from running.

1. Schedule check disk to run using chkdsk /f (STEP FIVE below) in the command promt.

2. Run msconfig (step 1 in METHOD TWO at link), and click on the Boot
tab and click on Safe boot with the minimal button selected. (See screenshot below)

3. Restart the computer to hopefully have chkdsk run.

4. Set msconfig (step 2 in METHOD TWO at link) to boot normally again.

5. If chkdsk still will not run at startup, then proceed with the steps below. If it did, then you're done.

1. Try running a sfc /scannow command to see if it can fix chkdsk.

2. When SFC is finished, try running chkdsk again.

3. If chkdsk still will not run at startup, then proceed with the steps below. If it did, then you're done.

NOTE

This will reset chkdsk back to it's default setting of not to run at startup. This step will also fix the problem of chkdsk always running at startup. If BootExecute already has a Data value of autocheck autochk *, then you do not need to do this. (See the Manual Way below to check) Continue to STEP FOUR below instead.
