How to bypass repairing disk errors Windows 10?

When you boot up your Windows 10 computer, it may automatically start scanning your drives and repairing disk errors. This is known as a disk check (chkdsk), and it can take a considerable amount of time to complete. Some users find the long wait frustrating, especially if they need to access their computer quickly. As a result, they look for ways to bypass or disable the disk check on startup.

There are a few reasons why users may want to bypass disk checks in Windows 10:

  • To reduce startup time – Disk checks can add minutes or even over an hour to the boot process if there are a lot of errors to repair.
  • When urgent access is needed – Users may need to urgently access their computer and don’t want to wait for the disk check to complete.
  • If errors don’t seem to impact performance – Sometimes the disk errors don’t appear to affect day-to-day usage, so users want to skip repairs.
  • When scans happen frequently – Repeated disk checks after every reboot can get annoying for some users.

However, it’s important to understand the risks before deciding to bypass disk checks in Windows 10. We’ll explore those next.

Understanding Disk Checks in Windows

CHKDSK is a tool built into Windows that scans the hard drive for errors and attempts to fix any issues it finds. It runs automatically under certain conditions or can be initiated manually by the user.

Windows schedules automatic CHKDSK scans on every drive after a certain number of drive restarts without being properly shut down. This helps ensure the integrity of the file system in case errors were introduced during an improper shutdown. CHKDSK scans the drive and looks for issues like bad sectors, lost clusters, cross-linked files, directory errors, invalid security descriptors, and more.

If CHKDSK detects any errors during the scan, it will attempt to repair them automatically. For example, it may recover readable information from bad sectors and then mark those sectors as defective to prevent future use. It will fix invalid file system entries, recover lost files if possible, set correct directory sizes, and repair invalid security descriptors. This automated repair helps avoid potential data loss or drive errors.

While the scanning and repair process can be time consuming, it’s an important maintenance task. Allowing the periodic CHKDSK scans to run on a schedule enables Windows to proactively detect and resolve issues before they have a chance to cause significant problems. However, advanced users can choose to disable or bypass CHKDSK if desired.


Risks of Bypassing Disk Checks

Bypassing disk checks can lead to serious risks that should not be taken lightly. The main risks include data corruption and complete disk failure.

Disk checks like chkdsk in Windows are designed to scan for and repair logical file system errors, bad sectors, and file corruption. If these errors are not repaired, they can get progressively worse over time leading to irreversible data corruption. Important files and folders may become unreadable. Entire partitions or drives can be rendered unusable if corruption spreads.

Additionally, bypasses like editing the registry do not actually fix the underlying disk problems. So physical errors on the disk will continue to accumulate. This increases the chances of catastrophic disk failures down the line, for example if bad sectors spread across critical parts of the disk.

In most cases, it is strongly recommended to allow disk checks to run instead of bypassing them. The minimal time investment is well worth avoiding massive data loss and expensive disk recovery/replacement costs. Only bypass checks if absolutely necessary and you have backups of critical data.

Editing Registry to Disable Chkdsk

One way to disable chkdsk on Windows 10 is by editing the registry. The registry contains configuration settings that control various aspects of how Windows operates. We can modify some values there to prevent chkdsk from running at startup.

To edit the registry, first open the Registry Editor by typing “regedit” in the Start menu search box and selecting the result. Then navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

In the right-side pane, look for a DWORD value named AutoChkTimeout. Double click it and set its Base value to 0. This will disable any automatic chkdsk scans at startup. You may need admin access to make these changes.

Next, navigate to this registry location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

Find the DWORD value BootExecute and set it to 0 as well. This prevents chkdsk from running before the Windows GUI loads.

After making the above registry edits, reboot your PC. Chkdsk should no longer start up automatically. Keep in mind that these tweaks prevent disk scans from being performed at all, so use them with caution.


Using Group Policy to Disable Chkdsk

One way to disable chkdsk at startup using group policy is by using the Group Policy Editor. This provides centralized management and configuration of operating systems, applications, and users in an Active Directory environment.

Here are the steps to disable chkdsk using Group Policy Editor on Windows 10:

  1. Open the Start menu, type “gpedit.msc” and press Enter to launch the Group Policy Editor.
  2. Navigate to Computer Configuration > Administrative Templates > System > Maintenance.
  3. On the right pane, double click on “Turn off automatic restart on system failure” and set it to “Enabled.”
  4. Now double click on “Disable recovery options” and set it to “Enabled.”
  5. Next, navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options.
  6. On the right pane, double click “Shutdown: Allow system to be shut down without having to log on” and set it to “Disabled.”
  7. Finally, click “OK” to apply the changes.

After applying this policy, chkdsk will stop running automatically at startup for all machines that the group policy applies to. Just reboot to make the changes take effect. Using group policy allows administrators to easily control chkdsk behavior across multiple computers.

Bypassing with Safe Mode

One way to bypass disk checks in Windows 10 is to boot into Safe Mode. Safe Mode loads a minimal set of drivers and services to get Windows up and running. Since chkdsk and other disk utilities do not run in Safe Mode, this can allow you to bypass any pending disk checks.

To boot into Safe Mode and skip disk checks:

  1. Restart your computer.
  2. As soon as the BIOS splash screen appears, press and hold the F8 key on your keyboard which will bring up the Advanced Boot Options menu.
  3. Select Safe Mode from the menu and press Enter.

Windows will now load into Safe Mode, bypassing chkdsk. You can then log into your machine and use it normally, aside from certain limitations of Safe Mode.

This method essentially postpones any needed disk checks rather than disabling them entirely. Once you reboot back into normal mode, chkdsk will run if it detects drive errors. So it only temporarily allows you to skip disk checks when necessary.[1]

Using Command Prompt

You can use the Command Prompt to bypass disk checks in Windows 10 by disabling the chkdsk utility. Here are the steps:

  • Open Command Prompt as administrator.
  • Type “chkntfs /x C:” (without quotes) and hit Enter. Replace C: with the drive letter you want to skip disk checking for.
  • This will disable chkdsk for the specified drive on next reboot.

Using chkntfs /x allows you to bypass disk checking on individual drives. However, this method must be repeated each time you want to skip the check. It does not permanently disable chkdsk.

While this method can bypass disk checks, it is not recommended. Allowing chkdsk to run regularly prevents potential file corruption and data loss. Bypassing chkdsk should only be done with caution.

Third Party Tools

If you want a quick and easy way to bypass chkdsk in Windows 10 without having to edit the registry or group policy, third party tools offer a simple solution. Apps like ChkFlsh provide an interface to disable automatic chkdsk operations at startup. These tools essentially function as chkdsk managers, giving you control over disk checks.

ChkFlsh and similar utilities work by directly interacting with the registry and system files to suppress chkdsk. After installing ChkFlsh, you simply need to run the app and toggle the switch to disable disk checking. This takes just a few seconds and doesn’t require any technical expertise.

The main advantage with third party tools is convenience. You don’t have to dig into the registry editor or group policy every time. Just run ChkFlsh whenever you want to bypass chkdsk before restarting your PC. The interface is user friendly as well. Overall, apps like ChkFlsh offer a quick way to suppress automatic disk checks in Windows 10.

When to Allow Disk Checks

While bypassing disk checks may sometimes seem convenient, there are risks associated with skipping scans and repairs. According to this Tom’s Hardware forum post, you should not skip disk checks since they help identify and fix disk errors.

Allowing the process to run is especially important if you notice performance issues, corrupted files, or other problems indicating disk errors. Skipping checks in these cases could lead to continued degradation and potential data loss. Disk checks are scheduled automatically by Windows after an improper shutdown to scan for and repair file system problems.

While the process can be slow, letting it run when prompted ensures your drive’s health and reduces the chance of bigger issues down the line. Exceptions could be made in urgent situations where booting immediately is critical, but otherwise it’s best to be patient and let the disk check run when notified on startup.


In summary, bypassing disk checks in Windows 10 can sometimes be beneficial to avoid delays, but it does come with risks. The main points are:

– Using registry edits, group policy, safe mode, command prompt or third party tools can disable or bypass disk checks like chkdsk.

– This can help avoid delays when booting up or shutting down Windows.

– However, disk checks are important for catching and repairing drive errors. Bypassing them means allowing potential corruption issues to remain unaddressed.

– Over time, unfixed errors can compound and lead to severe problems like data loss or disk failure.

– It’s best to only selectively disable disk checks when absolutely needed rather than permanently.

– If you do bypass checks, be sure to periodically scan your drive with chkdsk or other disk utilities.

In conclusion, judiciously disabling disk checks can provide some benefits but should be done with caution. It’s generally better to allow scans periodically, ensuring your drive remains in good health.
