There's a small boot utility to test physical memory from PassMark and I'd wish to add this tool to Windows 10 boot menu, but unfortunatelly the format in which Passmark delivers this tool (IMG) is so nonstandard that I'm not able to convert it to anything usable for Microsoft's boot manager. At least converting it to proper ISO and adding it to BCD store via EasyBCD would work, but the problem is that the IMG architecture is so strange that the resulting ISO has unrecognizable structure.

By using OSFmount I'm able to mount this image either as physical drive or logical one of the two contained partitions (2x FAT 256MB), then saving the virtual drive to ISO works but as I mentioned, it's not readable.

Any clue how to handle this really weird image for MS bootmgr would be very appreciated!

MBR boot or UEFI32 or UEFI64?





IMPORTANT: MemTest86 V8 images support only UEFI boot. On machines that don't support UEFI, MemTest86 will not boot. Please download the older V4 BIOS release of MemTest86 instead.





System Requirements
x86 based hardware, 32bit or 64bit
UEFI platform firmware
Windows, Linux, or Mac OS
USB Flash Drive (>= 512MB capacity)


You see how the new paradigm is to give to the user LESS choices (thanks to - stupid - UEFI)? :whistling:



@Franz Ferdinand II.

At first sight the disk image is pretty much standard, it has two FAT16 partitions, each with its own EFI bootloader (both 32 and 64 bit).

I have no idea how you can chainload it from BOOTMGR, though, ISO or not ISO, and - personally - I won't touch EasyBCD with anything but a 4' stick.


You will probably need to use GRUB2 "in the middle", but it wil probably be pesky if possible at all, memtest is "low level" enough to be incompatible with a number of boards (see bllacklist.cfg) so it has to be seen how it would react to an intermediate boot manager. :(






However, for UEFI systems that can only boot via CD/DVD media (such as systems with older UEFI implementations, or systems that only support remote boot via CD-ROM emulation through the BMC or IP KVM devices), we provide an (unsupported) CD/DVD ISO image of MemTest86 Free Edition for download.




Which BTW at first sight seems a lot like a pretty much normal hard disk emulation .iso with the same disk image inside.
