If 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:



Add the driver to any of the previously specified locations and click Retry.



If you do not remember the location, click Ignore to continue the process. If the result is not
satisfactory, reapply 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.

Universal Restore in Linux

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

When 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.

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 Universal Restore
cannot find a module it needs, it records the module’s file name into the log.

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.

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, 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 Universal Restore more than once (for example, after you have added missing drivers).

To revert to the original initial RAM disk, do any of the following:



Rename the copy accordingly. For example, run a command similar to the following:

mv initrd-2.6.16.60-0.21-default_acronis_backup.img
initrd-2.6.16.60-0.21-default



Specify the copy in the initrd line of the GRUB boot loader configuration.
