If your Windows 10 computer is not booting up properly or experiencing other issues, you may need to repair it. While using a Windows 10 installation disc is a common method, what if you don’t have one? Fortunately, there are several ways to repair Windows 10 without a disk. In this article, we’ll explore seven easy methods to get your system back up and running smoothly.

Method 1: Launch Startup Repair

If your computer is failing to load due to issues like the Blue Screen of Death or damaged Boot Configuration Data settings, you can use the built-in Startup Repair tool to fix the problem.

Here’s how to launch Startup Repair without a disk:

1. Create a recovery USB drive if your computer is unbootable.
2. Boot your computer from the recovery media.
3. Select your language, time, and keyboard input method, then click “Next”.
4. Click “Repair your computer”.
5. Choose “Troubleshoot” > “Startup Repair” to begin the repair process.

Another way to repair Windows 10 without a disk is to scan your system for errors using the System File Checker (SFC) tool.

Follow these steps:

3. Type “sfc /scannow” in the command line and press Enter.
4. Wait for the verification process to complete (100%).

If your computer fails to boot due to a damaged Master Boot Record (MBR), you can use the BootRec tool to fix the issue.

Here’s how:

1. Boot from the Windows installation media.
2. Select “Troubleshoot” > “Command Prompt”.
3. Type the following commands in the command line, pressing Enter after each one:

   • bootrec /fixboot
   • bootrec /scanos
   • bootrec /rebuildbcd
4. Reboot your computer and check if it boots normally.

Method 4: Run System Restore

If you have previously created a system restore point, you can use it to repair Windows 10 without a disk.

Follow these steps:

1. Access the Windows 10 Advanced Startup Options menu by performing a hard shutdown three times.

2. Click “Get started” under the “Reset this PC” section.
3. Choose whether to keep your files or remove everything.
