Activate
Activation enables the boot time prompt "Press F11 for Acronis Startup Recovery Manager…" (if you
do not have the GRUB boot loader) or adds the "Acronis Startup Recovery Manager" item to GRUB's
menu (if you have GRUB).
The system disk (or, the /boot partition in Linux) should have at least 100 MB of free space to activate Acronis
Startup Recovery Manager.
Unless you use the GRUB boot loader and it is installed in the Master Boot Record (MBR), Acronis
Startup Recovery Manager activation overwrites the MBR with its own boot code. Thus, you may
need to reactivate third-party boot loaders if they are installed.
Under Linux, when using a boot loader other than GRUB (such as LILO), consider installing it to a
Linux root (or boot) partition boot record instead of the MBR before activating Acronis Startup
Recovery Manager. Otherwise, reconfigure the boot loader manually after the activation.
Do not activate
Disables boot time prompt "Press F11 for Acronis Startup Recovery Manager…" (or, the menu item in
GRUB). If Acronis Startup Recovery Manager is not activated, you will need one of the following to
recover the system when it fails to boot:

boot the machine from a separate bootable rescue media

use network boot from Acronis PXE Server or Microsoft Remote Installation Services (RIS).
