With a Toshiba, you try tapping F12 when it boots.
That should get you to the boot menu
The MemTest86 test (not the MemTest86+) should be bootable directly from this menu.
To boot to the hard drive diagnostics, you'll have to change settings in the UEFI.
This includes disabling SecureBoot along with enabling CSM/Legacy boot options.
Each system is different, so it may take some experimentation
You may want to try this bootable diagnostic suite: http://support.lenovo.com/us/en/downloads/ds030861
I have not tried it myself, but the specs sound like it'll work for the hard drive test
I don't know if it'll limit itself to just Lenovo systems or not - but it's worth a shot if you have a spare USB drive.
Also, you may wish to try Rufus and add a bootable ISO to it
Rufus is free from here: https://rufus.akeo.ie/
I haven't done this one either, but it seems as if it'll work.
Still working on this one - can't get it to work for me.
Tried both Rufus and YUMI to boot Seatools/WD DLG/UBCD - and all failed on my system (but my BIOS/UEFI is setup a bit differently).
Will see what I can do at work tomorrow.
