Log in and start work – no additional reboots or otheractions are required.You can perform Active restore running Acronis True Image for Microsoft Small BusinessServer in Windows operating systems as well. However, it is mandatory to have bootablemedia in case Windows cannot boot.3.7 Acronis Universal Restore3.7.1 Acronis Universal Restore purposeA system disk image can be deployed easily on the hardware where it was created or toidentical hardware. However, if you change a motherboard or use another processorversion — a likely possibility in case of hardware failure — the restored system could beunbootable. An attempt to transfer the system to a new, much more powerful computerwill usually produce the same unbootable result because the new hardware isincompatible with the most critical drivers included in the image.Using Microsoft System Preparation Tool (Sysprep) does not solve this problem, becauseSysprep permits replacing drivers only for Plug-and-Play devices (sound cards, networkadapters, video cards etc.). As for system Hardware Abstraction Layer (HAL) and massstorage device drivers, they must be identical on the source and the target computers(see Microsoft Knowledge Base, articles 302577 and 216915).Acronis Universal Restore technology provides an efficient solution for hardware-independent system restoration by replacing the crucial Hardware Abstraction Layer (HAL)and mass storage device drivers.Acronis Universal Restore is applicable for:1. Instant recovery of a failed system on different hardware2. Hardware-independent cloning and deployment of operating systems3. Real-to-virtual and virtual-to-real computer migration for system recovery, test andother purposes.3.7.2 Acronis Universal Restore general principles1. Automatic HAL and mass storage drivers selectionAcronis Universal Restore searches the Windows default driver storage folders (in theimage being restored) for HAL and mass storage device drivers and installs drivers thatbetter fit the target hardware. You can specify a custom driver repository (a folder orfolders on a network drive or CD) which will also be used for drivers search.The Windows default driver storage folder is determined in the registry keyHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current version\DevicePath. Thisstorage folder is usually WINDOWS/inf.2. Manual selection of mass storage device driverIf the target hardware has a specific mass storage controller (such as a SCSI, RAID, orFibre Channel adapter) for the hard disk, you can install the appropriate driver manually,bypassing the automatic driver search-and-install procedure.3. Installing drivers for plug and play devicesAcronis Universal Restore relies on built-in plug and play discovery and configurationprocess to handle hardware differences in devices that are not critical for the system
