What is Acronis Universal Restore?
The Acronis Universal Restore tool is designed to help boot an operating system on a physical or a
virtual machine. The tool finds and installs drivers for devices that are critical for the operating
system start-up, such as storage controllers, motherboard, or chipset

Acronis Universal Restore is extremely useful in the following scenarios:
1. Instant recovery of a failed system on different hardware

2. Hardware-independent cloning and deployment of operating systems

3. Physical-to-physical, physical-to-virtual and virtual-to-physical machine migration

Installing Acronis Universal Restore
To install Acronis Universal Restore in Windows
1. Download the installation package from and save it

2. Run the downloaded .exe file

3. Follow the on-screen instructions

To install Acronis Universal Restore in Linux
1. Download the installation package from and save it

2. Go to the directory where the installation package (an .i686 or .x86_64 file) is located and run the
following command:
chmod 755 Acronis*

Creating bootable media
To create bootable media
1. Run the installed executable file

In Windows, the product is installed by default to the following folder:
l In 32-bit versions of Windows: %CommonProgramFiles%\Acronis\UniversalRestore

l In 64-bit versions of Windows: %CommonProgramFiles(x86)%\Acronis\UniversalRestore

In Linux, the product launcher is /usr/sbin/universal_restore

2. Follow the on-screen instructions. For details, refer to the built-in help

Using Acronis Universal Restore
To apply Acronis Universal Restore to an operating system, boot the machine from the bootable
media. If there are multiple operating systems on the machine, you are prompted to choose the one
to apply Acronis Universal Restore to

Acronis Universal Restore in Windows
1. Prepare drivers

Before applying Acronis Universal Restore to a Windows operating system, make sure that you
have the drivers for the new HDD controller and the chipset. These drivers are critical to start the
operating system. Use the CD or DVD supplied by the hardware vendor or download the drivers
from the vendor’s website. The driver files should have the *.inf, *.sys or *.oem extensions. If
you download the drivers in the *.exe, *.cab or *.zip format, extract them using a third-party

The best practice is to store drivers for all the hardware used in your organization in a single
repository sorted by device type or by the hardware configurations. You can keep a copy of the
repository on a DVD or a flash drive; pick some drivers and add them to the bootable media;
create the custom bootable media with the necessary drivers (and the necessary network
configuration) for each of your servers. Or, you can simply specify the path to the repository
every time Acronis Universal Restore is used

2. Check access to the drivers in bootable environment. Make sure you have access to the device
with drivers when working under bootable media. Use WinPE-based media if the device is
available in Windows but Linux-based media does not detect it

Acronis Universal Restore settings
Automatic driver search
Specify where the program will search for the Hardware Abstraction Layer (HAL), HDD controller
driver and network adapter driver(s):
l If the drivers are on a vendor's disc or other removable media, turn on the Search removable

l If the drivers are located in a networked folder or on the bootable media, specify the path to the
folder by clicking Add folder

In addition, Acronis Universal Restore will search the Windows default driver storage folder. Its
location is determined in the registry value DevicePath, which can be found in the registry key HKEY_
LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion. This storage folder is usually

Acronis Universal Restore will perform the recursive search in all the sub-folders of the specified
folder, find the most suitable HAL and HDD controller drivers of all those available, and install them
into the system. Acronis Universal Restore also searches for the network adapter driver; the path to
5 © Acronis International GmbH, 2003-2022
the found driver is then transmitted by Acronis Universal Restore to the operating system. If the
hardware has multiple network interface cards, Acronis Universal Restore will try to configure all the
cards' drivers

Mass storage drivers to install anyway
You need this setting if:
l The hardware has a specific mass storage controller such as RAID (especially NVIDIA RAID) or a
fibre channel adapter

l You migrated a system to a virtual machine that uses a SCSI hard drive controller. Use SCSI
drivers bundled with your virtualization software or download the latest drivers versions from the
software manufacturer website

l If the automatic drivers search does not help to boot the system

Specify the appropriate drivers by clicking Add driver. The drivers defined here will be installed,
with appropriate warnings, even if the program finds a better driver

Acronis Universal Restore process
After you have specified the required settings, click OK

If Acronis Universal Restore cannot find a compatible driver in the specified locations, it will display a
prompt about the problem device. Do one of the following:
l Add the driver to any of the previously specified locations and click Retry

l If you do not remember the location, click Ignore to continue the process. If the result is not
satisfactory, reapply Acronis Universal Restore. When configuring the operation, specify the
necessary driver

Once Windows boots, it will initialize the standard procedure for installing new hardware. The
network adapter driver will be installed silently if the driver has the Microsoft Windows signature

Otherwise, Windows will ask for confirmation on whether to install the unsigned driver

After that, you will be able to configure the network connection and specify drivers for the video
adapter, USB and other devices

Acronis Universal Restore in Linux
Acronis Universal Restore can be applied to Linux operating systems with a kernel version of 2.6.8
or later

When Acronis Universal Restore is applied to a Linux operating system, it updates a temporary file
system known as the initial RAM disk (initrd). This ensures that the operating system can boot on
the new hardware

Acronis Universal Restore adds modules for the new hardware (including device drivers) to the
initial RAM disk. As a rule, it finds the necessary modules in the /lib/modules directory. If Acronis
Universal Restore cannot find a module it needs, it records the module’s file name into the log

Acronis Universal Restore may modify the configuration of the GRUB boot loader. This may be
required, for example, to ensure the system bootability when the new machine has a different
volume layout than the original machine

Acronis Universal Restore never modifies the Linux kernel

Reverting to the original initial RAM disk
You can revert to the original initial RAM disk if necessary

The initial RAM disk is stored on the machine in a file. Before updating the initial RAM disk for the
first time, Acronis Universal Restore saves a copy of it to the same directory. The name of the copy is
the name of the file, followed by the _acronis_backup.img suffix. This copy will not be overwritten if
you run Acronis Universal Restore more than once (for example, after you have added missing

To revert to the original initial RAM disk, do any of the following:
l Rename the copy accordingly. For example, run a command similar to the following:
mv initrd-
l Specify the copy in the initrd line of the GRUB boot loader configuration
