|If you are sure that you don't have any way to recreate your system either from a hidden partition or by making disks then you might look at a few ideas. |
One is to buy them from Sony.
Make an image of some kind that can be returned hopefully by booting to some cd. Even if you have to borrow a Windows 7 cd to do it.
Make a backup/image to some media using linux live cd's.
Buy image software such as ghost or acronis or other.
I like to make a complete image of my system after I get it like I like it. When it dumps all I have to do is go back to that date.
The best solution is usually the OEM disks. They are stamped and not burned and don't fail as often.
