Boot windows from a CD problems!!

Hello ppl!

I have windows XP Pro in this PC ( Portuguese Version ), the CD its not original, but this PC suports CD Boot from the BIOS ( Its a PIII 800 with 3/4 years or so ) and it supports, but when i put the Windows CD on it says: "Boot from CD: none" and restarts...and i have to use the damm 6 boot disks wich take forever to complete.. :\

Here are the images of the Content of the XP CD´s ( the first is the Portuguese Version, the one im using now, and the other is the English version, also i have another one that has SP1 but its the same..dont boot ), both the CD´s when inserted on windows load normaly, the screen appears, all, but from DOS dont boot..:\ what is the problem? :\

Not as Cd-Rom are Bootable..
Make Custom CD who is Bootable is not easy either.

1) Check if your cd-rom is bootable with a legal Xp CD.
2) Check if your Custom CD boot on another computer.

You should help you solve your problem.
