  • How to chainload MemTest86 to Windows 10 boot manager?

    Hi there, this tool is offered as ISO or IMG for burning to CD/USB, which works. I wonder if it's also whichever way possible to integrate either the ISO or the disk image directly to Windows boot menu, either as another OS or replacement/another entry as to Microsoft memory Diagnostics. There's no way to hook ISO or IMG formats directly, only WinPE images (.WIM). If I look inside one of the two FAT partitions of memtest86-usb.img, I get this

    There's nothing like BOOT.WIM. But eventually extracting the whole partition somewhere to C:, then registering directly either the BOOTX64.EFI or BOOTIA32.EFI via bcdedit, probably the same class as MS MemDiag is registered (not WinPE either) could work.

    bcdedit lists MemDiag as this entry

    Windows Memory Tester
    identifier              {memdiag}
    device                  partition=\Device\HarddiskVolume2
    path                    \EFI\Microsoft\Boot\memtest.efi
    description             Windows Memory Diagnostic
    locale                  en-us
    inherit                 {globalsettings}
    badmemoryaccess         Yes
    So it's apparent registering boot choice as .EFI file is possible. I'm kinda lost in these formats but maybe the *.EFI files offer an usable entry point.
    Any clues to make the boot integration done would be appreciated.

    It isn't something we have attempted.
