    MemTest86+ version 5.01 Booting Failures/"Use of" Questions

    TenForums is the best source I've seen for MemTest86+ guidance, so here are two questions regarding MemTest86+ version 5.01.

    1. I downloaded a Memtest86+ V5.01 "Pre-Compiled Bootable ISO (.zip)" and extracted and burned the small ISO file to a DVD-RW. At the time my PC would only boot from a Windows Recovery CD or USB device. When I replaced a Windows Recovery DVD with the Memtest86+ ISO DVD, the PC continuously failed to boot. Finally came this explanation:

    ERROR: No boot disk has been detected or the disk has failed.

    Should I have downloaded instead the "Pre-Compiled Bootable Binary (.zip)?" I should mention that during disk creation I forgot to check off the "burn" confirmation box. But I find it doubtful disk creation failed.

    2. Before running MemTest86+ is it absolutely necessary to reset BIOS first boot order to CD or USB? Can't I simply use (in my case) F12 for "Setup" to initiate MemTest86+ from the CD or USB? I ask this because a) I see nothing in the MemTest86+ instructions suggesting it needs a reboot to finalize testing, and b) My recent highly troubled upgrade to Windows 10 Creators Update brought the above mentioned booting failure ordeal for which cause and correction remain undetermined[/URL]. By "correction" here, I mean a correction did in fact occur -- unexpectedly and unexplainedly. So although my PC now functions flawlessly under "Creators," I am leery about changing boot order at this time. Under the previous Windows 10 Version 1607 Anniversary Update the Windows Memory Diagnostic Tool consistently reported a hardware problem. But under "Creators" the tool consistently shows no memory problems.

    Hi WJB2,

    Welcome to the 10forums :)

    I'll have a look at some things for you, with a little luck there are only a few things you need to do.

    You shouldn't have to reset the boot order.
    When booting, before Windows loads, you should see 2 options at POST. 1 is to go to the BIOS and the other is to get a list of bootable devices. Choose the one with the list of bootable devices.

    I can't find what I'm looking for, does your BIOS have an option for legacy boot or similar options?

    MemTest86+ version 5.01 Booting Failures/"Use of" Questions

    First bootable device is the EFI; no Legacy option when viewed from BIOS (see here) .
    Attachment 151594
    Prior to this photo I had to remove the DVD with the Memtest86+ ISO because it endlessly spun, stopped, then spun again, keeping the HDD indicator solidly lit. To confirm the problem was the disc, not the internal "DVD Super Multi Drive," I inserted a Windows 10 64-bit Repair Disc. It worked fine, spinning into ready service and going quiet, with the HDD barely "winking" throughout. Prior to burning the Memtest86+ ISO the problem disc worked perfectly.
    So please at your convenience continue with your much appreciated guidance. In the meantime I will decide between eventually retrying a "Pre-Compiled Bootable ISO (.zip)" or placing a "Pre-Compiled Bootable Binary (.zip)" onto a USB drive.
    Finally ... not sure what you were looking for; online technical manual here.

    I'm looking for an option that enables legacy mode, I don't see an option to do this or it is not described.

    Enabling legacy mode (and disabling fast startup) make it possible to boot from a USB with memtest86+ for a long time if there were issues booting memtest86+.

    Didn't see it mentioned but I've never had luck with RW discs even if closed/finalized, only the R when wanting to boot to them.

    MemTest86+ version 5.01 Booting Failures/"Use of" Questions

    Well, Axe0's and Berton's comments provide potential options. Such as burning the MemTest86+ ISO to an R disk, which I have several of. Though during my recent, prolonged rescue efforts I had not one problem booting from a Windows 10 Creators Update ISO on disc. I'll also look for a way to disable fast start-up, which I'm sure there must be and will seek help if necessary from ACER Community forums.

    Will update as appropriate if/when successful. Thanks all!
