You must partition the drive before performing a restore whenever restoring to a new disk on the same controller (i.e. new and original disks are either both SCSI or both IDE) that is a different size than the original. From the restore menu, choose option Restore and View System/Disk Info to restore and view the sizes of the original disk before it was last seen by a bare metal backup. Write these numbers down.
Using the original disk sizes, make new partitions using option FDISK the Main Drive from the main menu. This creates a new MBR. When creating the new partitions, it is OK to make them bigger than the original, but if made smaller, the restore will have problems fitting all of the data onto a given partition.
This type of restore requires restoring using the option Restore Selective Partitions. Otherwise, if restore all is selected, the MBR will be restored, which will undo the work you did using FDISK to partition the drive.
