Some old motherboards chipsets cannot boot from the Windows 7 Installation CD
The easiest way is to boot from a Windows Vista System Repair Disk, go to fix computer option , got to command line, then insert Win 7 install disk, enter D:, enter cd sources, enter setup
I also had to update my motherboard bios first (ASRock) to be able to even boot from the vista disk. If your vista does not boot, check your bios (enter with F2 or Del right after booting and check the Bios version or see motherboard manufacturer website how to check this) download the newest version and burn to a CD. If it's not bootable by itself you need to create a DOS boot disk, boot from that and then use it - I used the
Ultimate Boot CD - Overview and booted the Netware DOS, the entered T: or whatever letter your CD drive has been assigned and updated the downloaded bios from another CD (Burn as simple ISO), then the vista boot disk worked
Have fun
