    With ventoy you just drop the ISO's on to the USB and thats it.

    How and what are you doing exactly?

    I've created a multible Windows editions + Snappy Installer on a 32gb flash drive
    I need to create a Windows 10 LTSC 2021 AiO ISO with x86&x64 compressed with ESD and compatible with UEFI as two seperate ISO's wont fit in the USB stick

    Download the UUP > ISO project and put in the separate x86 and x64 ISOs with install.esd and run "multi_arch_iso.cmd" and it will offer you 2 options to create the multi-arch ISO, see here for info:

    On UEFI it gives a .efi file error and on Legacy mode it only shows 32bit version
    I'm using el-gr_windows_10_enterprise_ltsc_2021_x64_dvd_c83eab34.iso and gr_windows_10_enterprise_ltsc_2021_x86_dvd_c7850ec0.iso

    This is the ISO creation process, this shows errors.

    First you showed VM in action but now you show the creation with errors.

    Best to verify the checksums for both ISOs.

    Thanks it works perfectly now I wanted to ask:
    How can I create a AutoUnattend.xml that when any of the LTSC version install is done it automatically skips the telemetry options and creates a user Administrator account?
    I tried that on NTlite but it only works on one version of the install of the AiO iso
