Which I have done many times as needed over the years.But now with the revocations for Secure Boot, does using Bcdboot like I did affect

  2. Windows 10 random automatic repair after changing boot priority.

    Hello. So i have an Windows 10 Pro. Sometimes when i am changing in bios boot order from USB to HDD ( SDD ) windows starts booting with AUTOMATIC REPAIR and then restarting. Is this something with BIOS \ Windows 10 bug related? Tested on pc and on laptop , and sometimes it doing the same.


    Situation on PC first,listen:

    Few days ago after i change boot in UEFI BIOS from USB to SSD.
    Then Windows 10 showed at 1 boot Automatic Repair.
    When starting Windows 10 boot loader starts by "preparing automatic repair" and diagnosing pc.
    Interesting is that if I restart Windows (after procedure mentioned earlier) it will boot normally. This startup problem was occured only when starting system again after shutdown or restarted pc from windows.So i was needed 2 boots to boot properly to windows.
    But on pc, format was needed to remove completely issue and after format is fine.

    Pc :
    2x8gb Kingston Hyperx 1600mhz DDR3
    SSD samsung Evo 250 gb
    4790k stock
    Asus Sabertooth Z97 Mark 2 with UEFI BIOS


    Now laptop with old standard bios:
    On laptop i made the same operation, change boot from USB to HDD and on first boot Windows 10 shows Automatic Repair. But it happened once and i cant reproduce. No format was needed.

    laptop is very old with 2gb ram

    Why on pc format was needed when on laptop not?



    Thanks for suggestions.

  3. 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.
