I used vLite to create a DVD with Vista Ultimate that included sp1. Everything appeared to work just fine. In fact, if I insert the disk it will auto-start and give me the option to install windows. However -- Seems like there's always a "however" doesn't it? -- the DVD will not boot. I want to use the Windows Repair function after installing a new mobo in my machine. Shouldn't the product of the Slipstream function be a bootable DVD?
