In this post, you’ll learn how to make a boot repair disk for Windows 10 & 11 to fix Windows boot failure issues.
A boot repair disk for Windows 10 is used when the operating system is unable to boot due to issues with the boot configuration or corrupted system files. There are several scenarios where a boot repair disk is necessary:
Corrupted or Missing Boot Files: If key boot files such as the Master Boot Record (MBR), Boot Configuration Data (BCD), or EFI partition are missing or corrupted, the system may fail to start properly. A boot repair disk allows you to repair these files.
Boot Loop: Sometimes Windows may get stuck in a boot loop where it repeatedly tries to boot but fails and restarts. A boot repair disk can be used to break this loop and fix the underlying issue.
Blue Screen of Death (BSOD): Certain critical system errors that cause a BSOD can prevent the system from booting. A repair disk can help fix these errors by restoring or repairing system files.
Failed Windows Updates: If a Windows update fails and corrupts system files, a repair disk can help recover from this issue and restore the system to a working state.
In short, boot repair disk can perform automatic repairs by scanning and fixing common boot issues, provide access to System Restore to roll the system back to a previous, working state, and offer command-line access via the Command Prompt for advanced troubleshooting tools.
Two methods for building boot repair disks are discussed in this part. The first is creating a USB from CMD that functions as both an installation and a repair USB. The second is a third-party program to create a boot repair disk to fix boot disk without entering the OS.
Step 1. Press “Win”+ “R” at the same time to open the “Run” dialogue. Input “cmd” and hit on the “Enter” key.
Step 2. When the Command Prompt opens, type “diskpart” and press “Enter” to launch the DiskPart.exe tool. Then execute the following command in sequence.
list disk select disk # clean create partition primary select partition 1 format fs= ntfs quick (If your Windows requires UEFI boot, format it as FAT32 with command “format fs=fat32 quick” instead) active
What if file copy fails?
If the Windows image file is over than 4GB, surpassing the file size limit of FAT32 file system, you will fail to copy files onto the USB flash drive. Once it happens, do as below:
1. Copy everything except the Windows image file (sources\install.wim) to the USB drive (either drag and drop, or use the following command, where D: is the mounted ISO and F: is the USB flash drive.) robocopy D: F: /s /max:3800000000
2. Split the Windows image file into smaller files, and copy them onto the USB drive: Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:F:\sources\install.swm /FileSize:3800
