Is the session on the disk closed?
When windows runs, it has drivers running that allow you access to open session disks.
That is not the case before windows drivers load.
Also, the disk has to be burned as a BOOTABLE disk for it to load the program's menu at bootup.
Whatever burning program you used, you should have choosen "make this disk bootable".
Using windows default burning software you can create a bootable disk, then add the files of your program to it.
