Windows PE with DiskPart and ImageX is a solid approach for copying a partition to another disk, especially if you're working within a Windows environment. This method is commonly used for system deployment, backups, and cloning.
Overview of the Process:
- Boot into Windows PE (Preinstallation Environment)
- Use DiskPart to prepare and partition the target disk
- Capture the source partition image with ImageX or DISM
- Apply the image to the new partition
- Configure the new partition (boot, assign drive letter, etc.)
Important Tips:
- Backup: Always backup important data before starting.
- Partition Size: To copy a partition to another disk. Ensure the target disk partition is large enough.
- Bootloader: You might need to repair or rebuild the bootloader.
- Compatibility: Use the correct image format and tools compatible with your Windows version.
