I have a machine with Windows XP and a separate CD player and DVD player in it. I want to do a fresh install of Windows 7 on it and I went into the BIOS boot sequence and don't see an option where I can make the DVD player the 1st bootable device. It shows the CD as an option but not the DVD. I have tried to boot to the CD with the DVD in the DVD player but no luck. Any words of wisdom would be appreciated.
