It turns out that Microsoft is going to let you create your own Vista repair disc when Service Pack 1 comes out in a month or so. If you can't wait that long, the nice people over at Neosmart have created their own Vista Repair Disc available for download.
The file is an ISO image file… if you are familiar then skip to the link, otherwise we've also got instructions on how to create a CD from the ISO file.
Burn Vista Recovery Disc ISO to CD
You may already have a tool to do this such as Nero, but the best tool available for burning ISOs is ImgBurn, a freeware utility that does nothing else but burn ISO images, and it does it well.
