    Default Leap 15.3 ISO to USB Legacy

    I could not find the way to write ISO image to USB with Legacy (MBR) that is not with EFI. Will it work if I delete the efi partition from the USB?

    Thanks

    The ISO has both, legacy and UEFI.

    The Installation decides on the Modus, if usind Legacy or UEFI.
    On Legacy, you will see on the first desktop the F-keys in the lower Row, on UEFI you have to hit the e-key.

    Use imagewriter or in terminal:
    Code:
    dd
    You can use this one to write it on USB:

    I am sorry that I have not stated my problem in sufficient detail. Let me try again:

    I have a PC with two SSDs one for Windows 10 and the other for Linux (Leap 15.2 at present). Both are Legacy (MBR) not EFI. So I have to instal Leap 15.3 in addition to existing Leap 15.2 in legacy mode. However when I write to downloaded file as ISO image to USB pen drive the drive is formatted for EFI. Though I have set up BIOS options to boot either EFI or Legacy, on pressing F12 the pen drive does not show up in boot options. I have tried all the options available (except setting up to boot from EFI only) but the pen drive just does not show up. I do not wish to mess up the existing installed systems.

    I am hoping to write the ISO image to pendrive with Legacy MBR. Can it be done?

    There is no "drive formatted to EFI".

    You can only "writre" an ISO with some special programms.

    What not is working is copying the files.

    The installer will use MBR or EFI to install depending on how it is booted. Boot installer in legacy mode and it installs the OS in legacy (MBR)

    That is what I understand, But I have been unable to write to USB in Legacy mode!

    I have still to try the "dd" method pointed out by JulianB and hcvv.

    By the way when I first downloaded the file name ended with x86_64. When my first attempt failed I thought that I had made some mistake so I downloaded again. The new filename ends with x86_63-Current.
    Is something wrong or there are two different files?

    Thanks
