Burn a Windows 7 Repair Disc
To burn your own Windows repair disc:
1. Click Start, type create and click Create a System Repair Disc
2. Insert a CD/DVD, choose the DVD drive in which the disc resides and click Create Disc
Once the disc is finished, I recommend booting from the disc to test it—before you really need it.
