  1. What is Secure Boot? Questions about Memtest86


    I have a few questions about Secure Boot and Memtest86:

    1. What is Secure Boot? If I accidentally downloaded a virus instead of Memtest86 and tried to run it on a bootable USB does Secure Boot stop it or can it get control over my whole PC? If I understand MS documentation correctly, is it a feature that allows only programs signed by Microsoft to boot from USB? Is Memtest86 signed by Microsoft?
    2. Can antivirus like Windows Defender detect malicious .img files?
    3. Is Memtest86 from this site safe to use? Why do I never see people like Linus or JayzTwoCents use it?
    4. Can Memtest86 damage my RAM by stressing it too much?

    Thank you for your answers

  2. Windows 8 Secure Boot Feature: Not So Secure?

    So Linux is switching to secure boot also? Or they have to because of UEFI?

    Windows 8 Secure Boot Feature: Not So Secure?

    • Linux
    • Linux
    • Linux
    • Linux
    • Oh and OSX
    Here is a statement from a Kernal Developer at Red Hat:

    I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.

    What is Secure Boot? Questions about Memtest86

    Memtest86 Free instead of Memtest86+


    Just a suggestion for users here who need to perform RAM tests to rule out hardware issues: Memtest86+ 5.01 has a bug with CPU multicore support (Parallel), as it hangs after some time testing and the only safe way to perform the tests is in single core mode, which is extremely low. This usually happens with test #7:

    Memtest86+ is freezing while running test #7

    The original proprietary version, Memtest86 6.2.0 Free, does not have this bug, which it means it performs the passes much, much faster than Memtest86+. Apparently, older builds of Memtest86+ do not hang with multicore support enabled as well.

    Another advantage of Memtest86 over 86+ is that it supports EFI+GPT, so you don't need to disable Secure Boot on UEFI menu to boot the USB drive with Memtest86 installed like you do with 86+, as it's installed only in MBR. The tests are the same, it perform 4 passes and it can even save a report in HTML format after ending the test. You can download the free version here:

    Here is the report in PDF so you can have an idea:
