Hi,
Make your own System Repair Disk from the information in this Tutorial:
"How to Create a Windows 7 System Repair Disc"

"This will show you how to create a Windows 7 system repair disc to be able to use to boot to **system recovery options** to help recover your Windows 7 installation if you don't have a Windows installation disc, can't find your Windows installation disc, or can't access the recovery options provided by your computer manufacturer.
A system repair disc is not able to install Windows 7.
Note
If you are unable to boot your Windows 7 to create a Windows 7 System Repair Disc, then you could create it on another computer to use on your computer."
