Burn a Windows Vista Recovery Disc
To burn your own Windows repair disc:
1. Click Start, type create and click Create a Recovery Disc
Note: The system repair disc utility is located in %systemroot%\system32\recdisc.exe
2. If prompted, click Continue on the User Account Control dialog:
3. 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.
