Vista boot disc / recovery disc

When you need to start Windows Vista from a CD/DVD because the version on the harddisk does not work properly anymore, the question rises how to make a boot disc? I had this problem recently on a laptop where there where disc errors on the C partition. Normally you could just schedule a disc check, unfortunately this did not work (chkdisc did not start). The truth is that I couldn't find out how to make a boot disc, maybe it is not even possible...

I found a solution though, you can download a recovery disc from this website. With this disc I was able to boot from CD and run chkdisc from the CD. The size of the download is approximatly 120 MB and best of all completly free.
