5.2 Recovering BIOS-based systems to UEFI-based and
vice versa
Acronis Backup supports transferring 64-bit Windows operating systems between BIOS-based
hardware and hardware that supports Unified Extensible Firmware Interface (UEFI).
How it works
Depending on whether the machine uses BIOS or UEFI firmware for booting, the disk with the system
volume must have a specific partition style. The partition style is master boot record (MBR) for BIOS,
and GUID partition table (GPT) for UEFI.
In addition, the operating system itself is sensitive to the type of firmware.
When performing a recovery to a machine that has a type of firmware that is different from the
firmware of the original machine, Acronis Backup:

Initializes the disk to which you are recovering the system volume either as an MBR disk or as a
GPT disk, depending on the new firmware.

Adjusts the Windows operating system so that it can start on the new firmware.
For details, including the list of Windows operating systems that can be adjusted this way, see
“Recovering volumes” (p. 148) and “Recovering disks” (p. 149) in this section.
Recommendations

Recover the entire system onto uninitialized disks.

When migrating to UEFI-based hardware, use Linux-based bootable media or WinPE-based
bootable media of versions later than 4.0. Earlier versions of WinPE and Acronis PXE Server do
not support UEFI.

Remember that BIOS does not allow using more than 2 TB of disk space.
