Steps to Convert Existing Partitions for use with UEFI Firmware

Unified Extensible Firmware Interface (UEFI) is a specification for a software program that connects your computer’s firmware to its Operating system. It is set to replace BIOS in the not-so-distant future.

Most systems use the Master Boot Record (MBR) partition scheme. Even though it works well with BIOS (Basic Input/ Output System), MBR has a lot of drawbacks. The GUID partition table (GPT) was made for this precise purpose – to provide secure access to BIOS available on newer systems.

As we make rapid technological advancements, the future lies in UEFI. In fact, all the storage devices larger than 2 TB or multi-boot systems running Windows, Mac, and Linux require GPT and UEFI or the system partitions won’t boot. MBR disks support only four partition table entries. If you need more partitions, you need to create an extended partition.

Not too long ago, you had to manually format your drives with the GPT scheme and reinstall the OS so they conform to UEFI requirements. While making this change, chances of data loss exist.

Here are ways to convert MBR to GPT.

  1. Using Windows interface
  • Back up or move data on MBR disk you want to convert to GPT disk.
  • If there are any partitions or volumes in the disk, right-click each of them and click Delete Partition or Delete Volume.
  • Now right-click the MBR disk that you want to convert and click Convert to GPT disk.
  1. Using Command Prompt
  • Back up or move data on MBR disk you want to convert to GPT disk.
  • Click on Start Type Command Prompt in the search bar.
  • In the search results, right-click on Command Prompt and select Run as Administrator.
  • Type diskpart. If there are no partitions or volumes, you can skip to Step 7.
  • In DISKPART prompt, type list disk. Note down the disk number that you want to convert.
  • In DISKPART, type disk <disknumber>.
  • In DISKPART, type clean.

Note that clean command will delete all your partitions or volumes on the disk.

  • In DISKPART window, type convert gpt.

If you lost data in the process of trying out any of the above solutions, Remo Recover software can restore all the data for you.

Data recovery using Remo Recover software

Remo Recover software uses strong built-in algorithms to scan the entire drive and restore data. The data recovery software is equipped to retrieve files from lost, deleted, formatted or re-formatted drives and partitions as well.

Check out how the software aids you in raw partition recovery.

Remo Recover can help you get back data from RAW hard drives as well. If the hard drive has bad sectors, the recovery tool creates a disk image bypassing all the bad sectors and then recovers data from this image.

The file systems supported by Remo Recover include FAT16, FAT32, NTFS, NTFS5 and ExFAT. Remo Recover works on all versions of Windows and Mac Operating systems.
