During a single session, you can recover several partitions or disks, one by one, by selecting one disk

and setting its parameters first and then repeating these actions for every partition or disk to be

recovered.

Disk and partition images contain a copy of track 0 along with the MBR (master boot record). It

appears in this window in a separate line. You can choose whether to recover the MBR and track 0 by

selecting the corresponding box. Recover the MBR if it is critical to your system booting.

When MBR recovery is chosen, the "Recover disk signature" box will appear in the bottom left corner

at the next step. Recovering disk signature may be desirable due to the following reasons:

1. Acronis True Image OEM Quick Backup creates scheduled tasks using the signature of the source

hard disk. If you recover the same disk signature, you don't need to re-create or edit the tasks

created previously.

2. Some installed applications use disk signature for licensing and other purposes.

3. If you use Windows Restore Points, they will be lost when the disk signature is not recovered.

4. In addition, recovering disk signature allows to recover VSS snapshots used by Windows Vista

and Windows 7's "Previous Versions" feature.

If the box is unselected, Acronis True Image OEM Quick Backup generates a new disk signature for

the recovered drive. This may be needed when you use an image backup not for disaster recovery

but for cloning your Windows Vista hard drive to another one. Trying to boot Windows after cloning

with both drives connected will result in a problem. During Windows booting, its loader checks the

disk signatures of all the connected drives, and if it finds two identical disk signatures, the loader

changes the signature of the second disk, which would be the clone disk. Once this happens, the

clone disk would not be able to boot up independently of the original disk, because the

MountedDevices fields in the clone's registry reference the disk signature of the original disk, which

will not be available if the original disk is disconnected.
