If you have a computer with a Unified Extensible Firmware Interface (UEFI) motherboard, you may find that some of the backup and cloning software do not work well. Therefore, you need to find a UEFI disk imaging and cloning software. UEFI is a new specification largely used by recent hardware as a replacement to BIOS.
Compared to the old boot mode, BIOS based Legacy mode, UEFI mode has many advanced features. For most of the users, the most essential is that it support booting form hard drives larger than 2TB by using GPT partition style. Besides, it improves the startup time.
However, as all the new advanced technologies, UEFI does not compatible with some old operating systems (OS) and software. All the 32 bit Windows systems before Windows 8 and 64 bit system before Windows XP do not have support for UEFI.
Freeware with full UEFI supports
AOMEI Backupper Standard is the best disk imaging software as well as cloning software for Windows 10/8.1/8/7 that completely support UEFI. Whether you prefer backup or clone feature, AOMEI Backupper can content you with its excellent performance.
For backup job, it allows you to backup system, partitions, disks, files and folders to any locations that your computer can recognize. It enables you to keep scheduled backup tasks while saving disk space by providing incremental and differential backup technology. （Scheduled tasks with differential backup supported by AOMEI Backupper Profeesional. What’s more, it lets you to restore system backup or disk backup to dissimilar hardware.
As a hard drive cloning software free version, it provides 2 ways to transfer data or system to another storage device, Partition Clone, and Disk Clone. When using AOMEI Backupper to clone hard drive to SSD, you don’t have to worry about the SSD is too small, because AOMEI Backupper allows you to clone large HDD to small SSD as long as your SSD has the capacity for the data on the HDD.
What’s more, it allows you to restore or clone from UEFI/BIOS to BIOS? UEFI system while ensure the destination disk bootable without the need to convert disks. In conclusion, you do have to concern the firmware (UEFI or BIOS) while doing a clone or restore with AOMEI Backupper.
Clone system regarding its firmware
As you know, UEFI and BIOS are supported on different types of disks. You can only use a GPT disk to boot with UEFI mode, and MBR disk with Legacy mode BIOS based. If you want to clone GPT to MBR disk, make sure the source disk has no more than 4 partitions, because MBR disks only support at most 4 primary partitions. If you want to clone MBR disk to GPT disk, make sure your system and hardware support UEFI.
To Clone hard drive form MBR disk (BIOS) to GPT disk (UEFI):
1. Download and run the free cloning software.
2. In the main interface, Click Clone button, and in the right panel, select Disk Clone. If you only need to transfer OS to another hard drive or SSD. Then you can use System Clone (which is available in Professional edition). It will automatically select the system partition (C drive) and system reserved partition as the clone source.
3. Click Step 1 to specify the source disk that you want to clone and click Step 2 to select the destination location. Note that the selected partition will be deleted before the transferring data.
4. Then it will bring you to the Operation Summary screen. If you want to clone UEFI disk to SSD, check the “Align partition to optimize for SSD” option, and then click “Start Clone” to start the cloning process if there is no problem.
After the cloning, you only need to make sure the Legacy boot mode enabled and then you can boot your computer from the cloned drive. Both the imaging and cloning process will be running in the background, so your work with the computer will not be interrupted. As a free UEFI disk imaging and cloning software, AOMEI Backupper also allows you to restore system regardless of its firmware. You can use it to restore bios based system to uefi based computer without manually changing anything. It just works.
