Move to New Hardware and Convert MBR/BIOS to UEFI

Key References

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.
