Clone a partition, but not the entire drive

I am using Acronis True Image Home 2009 on a USB boot drive (Bart PE).
I have a new 320GB hardrive with two partitions on it; one for an operating system (D:), and one for data (W:).
I would like to clone a single partition 60 GB drive (C:) with an operating system and programs onto the first partition of the 320 GB drive, and leave the second parttion data portion of the drive intact.
e.g.
Drive 1; 60GB, Single partition, operating system and programs (Source drive) (C:)
Drive 2; 320GB, two partitions as follows:
Partition 1 - 80 GB (reserved for operating system (Target) (D:),
Partition 2 - 240 GB that contains data I want to preserve (keep data, no changes)(W:).
I can not find a way to clone the operating system from Drive 1 onto the partition 1 of the new drive 2.

Can anyone tell me how this may be accomplished?
