Cloning EFI Partition? What Will You Need?

Since cloning an EFI partition to another drive entails moving important data, keeping everything in place is important to guarantee a safe and secure transfer. The key factors that you need to consider before you think of cloning the EFI partition include the following:

  • Prepare an HDD/SSD: to ensure a successful transfer, the target drive (whether HDD or SSD) must be able to store the EFI partition. Therefore, you must ensure that there's enough storage space. If not, you can try clearing space or using a larger drive.
  • Backup data on the old drive: it's important to back up the data on your old drive to minimize data loss incidences when you want to move your EFI partition to another drive. This ensures you have somewhere to return to if things don't go your way. An efficient free backup software that you can use for this activity is EaseUS Todo Backup.
  • Prepare a USB-to-SATA cable: since the cloning process entails moving boot files and settings from one drive to another, you need a connector. One of the best tools that you need for this process is a SATA-to-USB cable. Ensure you have a functional cable, or purchase one if you don't have one.
  • Download a reliable disk cloning tool: lastly, the cloning process can't go on if you don't have cloning software. Such software allows you to move the EFI system partition from your old drive to a new one. One cloning software that we recommend (and that we've used in this guide) is EaseUS Disk Copy. Ensure you download it to your computer.
