    How to build a multi-boot USB under UEFI


    I am trying to build a multi-boot USB under UEFI but am having no luck. I am trying to build a 4GB USB with the following bootable applications:
    - Acronis Boot Media 2017
    - Clonezilla 2.6.3.7
    - GParted 1.0.0.5
    - Samsung SSD Eraser

    I have tried using YUMI 2.0.6.9 and XBoot 1.0.14. However, when I create a complete USB with all the aforementioned applications, the USB is not seen as a bootable device under UEFI.

    I can successfully build a bootable USB for either Acronis Boot Media 2017 or Samsung SSD Eraser on their own (not together), but this obviously does not solve the problem of needing all 4 applications. Also, the USB is bootable if I switch from UEFI to legacy BIOS, but again, this does not solve the problem, because I installed Windows 10 under UEFI so want to have access to the same environment.

    There must be a solution to this as I am sure many people have succeeded in doing this, but I just cannot figure it out and see what I am doing wrong.

    I would really appreciate any help on this, and if someone who has succeeded in doing this, can give me a step-by-step guide that would be great; although I have already read many tutorials on this without success.

    I am running Windows 10 Pro x64 10.0.19008.1000 (Yes, I am enrolled on the Windows Insider Programme)

    You may need to turn Secure Boot off in the BIOS. It generally is defaulted to ON by the MB makers to prevent unauthorized external boot devices, like thumbs and DVDs.

    Then, possibly, change the boot order to see the USB first, if present.

    32-Bit UEFI Booting is not supported.. Except on ATOM processor..
    Acronis & Samsung both support x64 Bootable Media - thus UEFI

    I guess that was the one thing I forgot to say. "Secure Boot" has always been switched off, so this should not be the problem.

    Both GParted and Clonezilla are the x64 versions.

    well , then it is a matter of how your are trying to create your media...
    You should only have ONE bcd - pointing to different Source Folders
    ie Samsung/source - Acronis/sources - gparted/files - clonzilla/files

    then you added those sources into the EFI/ boot menu

    This is where my knowledge is sadly lacking. I tried using YUMI and XBoot and simply followed the basic instructions of loading the .ISO files and letting the tools do their thing. The option I had to choose which I may have done wrong was choosing between: "GRUB4Dos", "GRUB to RAM" or "Syslinux". I tried all 3 but to no avail.

    Also, the USB is not seen in the UEFI setup as a bootable device, nor is it listed in the boot menu via F7, so maybe there is something else going on?

    To Be UEFI Bootable the Boot Manager has to be on a Fat32 Partition...

    Apologies for not responding for a while.

    I am still unable to get this to work. I did a simple test using an Acronis ISO and YUMI boot builder. I formatted the USB to FAT32 and used GRUB for the boot loader. UEFI sees the USB in the boot order menu (F7) but does not boot from it.

    I tried zipping and uploading the contents of the USB to post here, but the upload did not work. Is there any specific file content I can post here to help you identify the problem?

    Just to be clear, earlier in this thread I mentioned I got Acronis to boot, however, this was not using YUMI, this was building the USB direct from the Acronis application.

    you would have upload to your cloud account and then post a link to it..
    This is due to forum upload size limitations..

    I do not have any cloud accounts to upload to. The biggest file in the ZIP by far is the Acronis ISO. I could exclude that and try again if that would help?
