• Microsoft Windows Partitioning Guide
• Microsoft Sample Deployment Scripts (includes partition script)

Overview Steps

1. Obtain backup of target system (VHD or Macrium image of all drives preferred)
2. Manually partition destination disk (Boot to WinPE/Macrium Recovery, see script below to partition)
3. Restore C: partition from backup to Windows partition on the new (now GPT) disk
4. Repair Windows Boot (Fix Windows Boot Problems)

Tips

• Use Macrium Reflect Free – backup to external drive and test prior
• A fast external hard drive will make this step much easier. Store the backup image on it, then move it to the new machine to restore.
