I can't recall having seen jumpers on my SATA drives, but you may have to boot from the drive on connector 1 (or whatever they call it). On my MB (ASUS P5W DH Deluxe) SATA connector 1 is specifically called "Boot" and the rest "Data", although it is possible to use 1 as a Data drive, if I boot from a PATA drive.
There are no jumpers on SATA drives. Some BIOS' allow you to pick which drive you want to boot off of. I'm using Gigabyte motherboards and they give you this option.
It sounds like you are already booting to Windows off your original drive. Have you formatted the new drive? Right click on My Computer and select Manage. Then click on Disk Management in the left window. You should see the new drive as Disk 1. If it doesn't have a drive letter assigned, then you'll need to give it one. Then look to see if it's formatted. It should show how many GB and the file system such as NTFS on the middle line. The bottom line will show Healthy if the drive is formatted and working properly.
Which version of Partition Magic are you using? Some versions don't support the current drive sizes. If you have PM 8.0, then make sure you upgrade that version. It's either 8.01 or SP1 you add. Then you may need to add another additional patch which corrects a couple issues with the last update. See Symantec's website.
