This is particularly useful for fixing boot errors, resizing the system partition, or migrating an OS when the computer won't start normally. Key Capabilities of the Bootable USB
Fix Boot Issues: It can rebuild the Master Boot Record (MBR) if your PC fails to start due to a "Bootmgr is missing" or "Operating System not found" error.
Partition Recovery: It helps recover lost or deleted partitions even if the OS is inaccessible.
Disk Conversion: You can convert a system disk from MBR to GPT to support modern UEFI boot modes or manage drives larger than 2TB.
Hardware Compatibility: For the best compatibility across different systems, EaseUS recommends formatting the USB to FAT32. Comparison with Alternatives

The process of generating the bootable media is designed to be user-friendly, abstracting the complex command-line inputs usually associated with native Windows ADK (Assessment and Deployment Kit).
