dvd with windows 10 image not booting

Hello, i have created an iso and burned on dvd, with an image of windows 10 (that i have generalized and modified). Basically i have changed the install.esd file with the install.wim file. all good.

When i try to boot  from a an external dvd player on a dell vostro desktop i cant see the player and boot from dvd. But if i put inside the original  dvd from windows 10 i can see it.

So i am wondering why is not working ...could you please help me with that....

Thanks in advance
