    Good afternoon syngef01 !

    I really did not understand your problem well.
    Is your laptop with which OS is installed?
    How did you create bootable media? With Rufus?
    Want to perform a dual-boot?
    Did you disable SecureBoot on Bios?
    Set the external DVD to be the first boot to boot?
    Did you create the installation media with UEFi support?
    Did you use ISO x64?

    I have the resource dvd to reinstall windows... the OS installed on the laptop is Ubuntu 19.04, in the bios I have changed UEFI to legacy to allow me to boot on the external dvd drive

    Some questions are not right.

    1- If the HDD is in GPT and Bios in UEFi, both operating systems, both Windows and Linux, must be installed with UEFi support.

    2- There is an installation order:
    First is installed the Windows system and only after the Linux system.
    If you install Linux and then Windows, the Windows Boot Manager will overwrite Grub and Linux will be lost.
