A system repair disc only needs to be created once.
A system repair disc is not a system image disc(s).
If you have repartitioned your drive, then a new System Image created using Windows Backup and Restore is definitely to be performed.
Here is how you make a System Repair Disc. System Repair Disc - Create
DISC - CREATE A SYSTEM REPAIR DISC START
| type System Repair
key | Create Disc
I recommend, if you haven't already, that you create a system repair disc which will fit an a normal CD.
Boot from the System Repair Disc and familiarize with the options there.
