-
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.

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.
