Create recovery disks when Windows 7 will not load
You should be able to initiate a boot to the repair partition without creating the recovery disks. Normally, you must have access to the OS to actually create these disks.
Sony's usually use the F10 key to access this recovery partition. Pressing F10 while the system is loading (just like F8 for the Windows boot options menu) should open whatever recovery system Sony installed on the laptop.
If F10 doesn't work, post the full model number of the laptop so we can look up the specific instructions for that model.
