Vista - Transferring VISTA etc to new Hard Drive

I have a HP Pavilion TX1340 laptop with a 120GB 2.5" SATA HD running Vista Home Premium. The 120GB HD has two partitions. One is the 104GB is Local Dive C and the other the 7.48GB is the HP Recovery Drive D.

I am now in the process of preparing a replacement 320GB HD.

The 320GB HD is in a USB2.0 caddy and has been initialized and formatted. I have used Acronis True Image 10.0 to clone the two partitions mentioned above on the original 120GB HD over to the new 320GB HD and these are called Local Drive G (104GB) and HP Recovery Drive H (7.48GB). The remainder of the 320GB hard drive is now a third partition called Data Drive I (186GB).

I chose this layout as the laptop will only recognise drives up to 250GB.

What do I need to do/check on the new 320GB HD (partitions G, H and I) to ensure that it will boot up when I place it in my laptop? Do I need to change drive letters of will this be done automatically? Do I need to set up drive G to be the bootable drive?

I do hope you can understand this rather detailed and perhaps confusing description.
