Additional information
Disk letters in standalone Acronis True Image 2021 might sometimes differ from the way Windows
identifies drives. For example, the D: disk identified in the standalone Acronis True Image 2021 might
correspond to the E: disk in Windows. The disk labels and information on partition sizes, file systems,
drive capacities, their manufacturers, and model numbers can help in correctly identifying the disks
and partitions.
You won't be able to use the previously activated Acronis Startup Recovery Manager if the
Try&Decide is turned on. Rebooting the computer in the Try mode will allow you to use Acronis
Startup Recovery Manager again.
Does Acronis Startup Recovery Manager affect other loaders?
When Acronis Startup Recovery Manager is activated, it overwrites the master boot record (MBR)
with its own boot code. If you have any third-party boot managers installed, you will need to
reactivate them after the Startup Recovery Manager has been activated. For Linux loaders (e.g. LiLo
and GRUB), you might consider installing them to a Linux root (or boot) partition boot record instead
of MBR before activating Acronis Startup Recovery Manager.
UEFI boot mechanism is different from the BIOS one. Any OS loader or other boot program has its
own boot variable that defines a path to the corresponding loader. All loaders are stored on a special
partition called EFI System Partition. When you activate Acronis Startup Recovery Manager in
UEFI-booted system, it changes the boot sequence by writing its own boot variable. This variable is
added to the list of variables and does not change them. Since all loaders are independent and do
not affect each other, there is no need to change anything before or after activating Acronis Startup
Recovery Manager.
13.4 Try&Decide
When you turn Try&Decide on, your computer is in the Try mode. After that you can perform any
potentially dangerous operations without worrying that you might damage your operating system,
programs or data. When you turn Try&Decide off, you decide if you want to apply the changes to
your computer or you want to discard them.
When Try&Decide can help
We recommend that you turn Try&Decide on before you try to:
Change any system settings, when you are not sure how these changes may affect your
computer.
Install system updates, drivers, etc.
Install unfamiliar applications.
Open mail attachments from unknown senders.
Visit websites that might contain potentially troublesome content.
