How to create a bootable Memtest86+ on USB flash drive?

Question

Normally, this should not be a problem. But usually, it always is. The Memtest86+ website hosts a specially prepped EXE auto-installer file that will format your USB flash drive, copy Memtest86+ binaries to it and make it bootable.

It's packed as a ZIP file and should work with Windows 7. The name of the file you run is Memtest86+ USB Installer.exe but I am having no luck with it today. Simply because I am unable to select my USB flash drive from the drop down menu. The menu is not showing any selectable item.

I tried version 5.01 and 4.20 on Windows 7 and got the same results. Can't select my USB flash drive. The flash drive is a SanDisk 4 GB Cruzer Blade, just unwrapped, brand new. I had it formatted with FAT32 inside Explorer to get rid of the extra software that SanDisk puts on it. I also rebooted Windows to make sure drivers are loaded. I can use the flash drive to copy files back and forth effortlessly, it just won't show up in the Memtest86+ prep tool.

I did try downloading the pre-compiled bootable binary for version 5.01 and tried to prep the USB flash drive with it using Linux Pen Drive. Inside this tool (Universal-USB-Installer-1.9.5.2.exe) I selected "Try Unlisted Linux ISO". I got the same problem here. The USB flash drive is just not showing up.

However! Inside this tool you can select "Show all Drives". That way I can select my USB flash drive and hit the Create button.

It starts working on it but then returns an error. Some files are copied to the USB flash drive.

What else can a man do to get this thing working?

Logs are always nice...

For non-EFI machines and EFI implementations that do not not support memtest86.

Tools required

parted, dosfstools, gzip, tar, wget

Define USB device, memtest86+ version and SYSLINUX version

USB=/dev/sdX # where X corresponds to USB device
MEM=5.31b
SYS=6.03

Download URLs

MEMTESTB=http://www.memtest.org/download/${MEM}/memtest86+-${MEM}.bin.gz
SYSLINUX=https://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-${SYS}.tar.xz

Partition USB and create 4MB FAT16 filesystem

parted -s ${USB} mklabel msdos mkpart primary fat16 2048s 5mib set 1 boot on
sync; sync; sync
mkfs.vfat -nMT86PLUS ${USB}1
mount ${USB}1 /mnt

Download and install memtest86+ binary

wget -qO- ${MEMTESTB} | gzip -d > /mnt/mt86plus

Create SYSLINUX configuration file to start memtest86+ binary

cat >/mnt/syslinux.cfg <<'!'
PROMPT 0
TIMEOUT 0
DEFAULT mt86plus
LABEL mt86plus
  kernel mt86plus
!

Download SYSLINUX, install MBR code and install SYSLINUX to USB

wget -qO- ${SYSLINUX} | tar -xJpf -
dd bs=440 if=syslinux-${SYS}/bios/mbr/mbr.bin of=${USB}
syslinux-${SYS}/bios/linux/syslinux -i -s ${USB}1
umount /mnt

Cleanup

rm -rf syslinux-${SYS}

This is admittedly a somewhat roundabout way, but it does let you run Memtest86+ from a USB! The way I ended up doing it was grabbing a Fedora Workstation ISO from https://getfedora.org and putting that onto the USB. Now, you might be wondering what Fedora has to do with this, but on their installer image Memtest86+ is available to be booted.
You will first be taken here. Select Troubleshooting. If you do not see this screen and you're on a UEFI system, try booting the USB via legacy boot/BIOS boot.

Here, choose Run a memory test

You should now be booted into Memtest86+!

Skip Memtest86+! Go to Memtest86! Run! Done!

I've done what was asked of me, and according to the authors website. But it didn't work anyway. So what I have done is I used another Memtest 86 program. The original Memtest86 line, now up in version 5 (new free software license), and owned by PassMark. It was a breeze using it and making the UFD bootable. It's as simple as ABC.

Go to Memtest86.com.
Click on the link "Image for creating bootable USB Drive". This
will download the file
http://www.memtest86.com/downloads/memtest86-usb.zip for Windows.
Unpack the ZIP file.
Run the imageUSB.exe file and follow onscreen instructions.

This should work on both BIOS and UEFI BIOS systems. On UEFI systems you can even use the mouse pointer to navigate.

You can see it had some issues with checksums but it was false alarm, verification passed.
