    How to make active@boot disk bootable on uefi/gpt?


    Hey Guys

    Does anyone know how this software can be configured to boot from usb on uefi/gpt.

    I formatted usb using rufus on the relevant mode then dragged over the contents of another usb where it does work on bios/mbr set up.
    But when booting from it on the uefi set up , I get the error " no operating system found"?

    I have compiled the software into an iso then tried rufus , but rufus states the iso is not efi?

    Can anyone shed any light on this?

    Many thanks.

    How to make active@boot disk bootable on uefi/gpt?-capture.jpg

    This is what i did to create a Bootable USB disk for Windows 10.
    I selected GPI partition scheme and formatted my USB with FAT32 filesystem using Windows 10 ISO image. All went smooth.

    You said you dragged over the contents of Another USB which was bootable and working? I think that's not gonna work by just copying and pasting the content from Bootable USB to another USB.

    Try formatting USB by using RUFUS tool and select ISO image then hit the Start button until green bar completes and it says "Ready".

    Do you see a bootmgr.efi on the USB thumb drive? That has to be there to boot in UEFI mode.

    This is the way I do it.

    Extract the contents of the ISO to a folder, insert your usb drive.

    Open a command prompt.

    1. In the command prompt, you need to execute the following commands.
    Type DISKPART and hit enter.
    Now, type LIST DISK and press enter to see list of disks attached to your computer. In the next step, you need to select your USB flash drive that you are using to create system install drive (in this example, we are selecting Disk 1).
    From now on, type all the following commands one by one and then hit enter (again, please make sure that you are replacing the DISK 1 with your Disk number).
    SELECT DISK 1
    CLEAN
    CREATE PARTITION PRIMARY
    SELECT PARTITION 1
    ACTIVE
    FORMAT FS=NTFS
    (Format process may take few seconds)
    ASSIGN
    EXIT
    copy all the contents to your USB from the folder.

    - Added support for UEFI Secure Boot mode.
    How to create UEFI Boot Mode compatible USB flash drive, which is only bootable in UEFI Boot Mode.

    Format your USB flash drive. Note: You need to choose the FAT32 file system.

    When formatting is complete.
    - In Windows 8/10, mount the ISO image file by right-clicking the ISO image file and choosing Mount. If you donít see Mount command from the context menu, go to Open with -> Windows Explorer instead.
    - Select everything in the mounted ISO image file, and copy them into the USB flash drive you prepared earlier.

    Note: UEFI Boot Mode do not use boot sectors on the hard drive (and the USB flash drive) and do not require active partition to be set.

    I am going to throw myself from a first floor window. Never have I seen such problems to install a operating system contact the manufacturer they will advise the correct operation.

    The title of the thread, and in his post, he says he is trying to make an "active@boot" USB. He's not installing an operating system.

    OP, the company that makes the active@boot disk clearly states in their FAQ that they do not support UEFI in any way. You must use legacy mode to boot their product.

    I'm downloading a copy of their boot image to inspect it and determine whether or not it is possible to modify the image to UEFI boot. If this tool is DOS based though, as I suspect it is, then it's much more trouble than it's worth to attempt to boot it in non legacy mode.

    I remember a similar situation many years ago and believe I fixed it by using a a program such as ultraISO or something similar.
