Acronis Backup & Recovery 11 supports transferring Windows operating systems between BIOS-based hardware and hardware that supports Unified Extensible Firmware Interface (UEFI).

Important: When migrating systems to UEFI-based hardware, use Linux-based bootable media, since PE-based

5.3.1 Recovering volumes

Let's assume you backed up the system and boot volumes (or the entire machine) and want to recover these volumes to a different platform. The ability of the recovered system to boot up depends on the following factors:



Source operating system: convertible or non-convertible OS. The following Microsoft Windows operating systems are convertible, that is, allow changing the boot mode from BIOS to UEFI and back:



Windows Vista SP1 x64 and later.



Windows Server 2008 x64 SP1 and later.



Windows 7 x64.



Windows Server 2008 R2 x64.

All other operating systems are non-convertible.



Source and target disk partition style: MBR or GPT. System and boot volumes of BIOS platforms use MBR disks. System and boot volumes of UEFI platforms use GPT disks.

When selecting not initialized target disk for recovery, this disk will be automatically initialized either to GPT or to MBR depending on the original disk partitioning style, the current boot mode (UEFI or BIOS) and the type of operating systems (convertible or non-convertible) that are located on this volume.

If the initialization may result in bootability loss, the software takes the partitioning style from the source volume ignoring the target disk size. In such cases the software can select the MBR partitioning style for disks whose size is more than 2 TB; however, a user cannot use the space beyond 2 TB.

If required, you can initialize the target disk manually by using the Disk management (p. 242) functionality.

The following table summarizes whether it is possible to retain the system bootability when recovering boot and system volumes of a BIOS-based system to UEFI-based and back.



The plus (+) sign on a green background means that the system will be bootable. No user action is required.



The plus (+) sign on a yellow background means you need to perform additional steps to make the system bootable.



The minus (-) sign on a red background means the system will not be able to boot due to BIOS and UEFI platform limitations.

5.3.2 Recovering disks

Let's assume you backed up a whole disk (with all its volumes) and want to recover this disk to a different target platform.

The ability of the recovered system to boot up in different modes depends on the operating systems installed on the source disk. Operating systems can be convertible i.e. allow changing the boot mode from BIOS to UEFI and back, or be non-convertible. For the list of convertible operating systems, see Recovering volumes (p. 138).



When a source disk contains one or more operating systems and all of them are convertible, the boot mode can be automatically changed. Depending on the current boot mode, the target disk may be initialized either to GPT or to MBR partitioning style.



If at least one operating system on a source disk is non-convertible (or the source disk contains any boot volumes of the non-convertible OSes), the boot mode cannot be changed automatically and the software will initialize the target disk as the source one. To boot up the target machine, you have to turn on/off the UEFI mode in BIOS manually. Otherwise, the system will not boot after recovery.

The following table summarizes all cases of recovering disks of a BIOS-based system to UEFI-based and vice versa.



The plus (+) sign on a green background means that the source disk will be recovered without any limitations.



The plus (+) sign on a yellow background means that the source disk will be recovered with some limitations. To overcome such limitations, you might need to perform some additional steps.



The plus/minus (+/-) signs on a red background means the disk will be recovered, but some issues might occur.

The target disk will be initialized as MBR. Limitation: only 2 TB of the disk space will be available for use. To overcome the limitation:

1. Turn on the UEFI mode in BIOS 2. Boot from a

bootable media, and perform the recovery. As a result, the recovered OS will be converted to use UEFI for booting.

The target disk will be initialized as GPT. The recovered disk OS will be automatically converted to support UEFI booting. Note: If you want to recover the source disk “as is”:
