Secure Boot - Enable or Disable in UEFI

  1. #80

    yes. I have 4 partitions on my boot drive, all created by windows, System Info tells me Bios mode is UEFI

    How do you clear the secure boot keys?

    edit: looking in my motherboard manual, there seems to be a secureboot mode setting that can be set to [custom], which will then enable a key management sub-menu. I am not seeing any info on that sub-menu though.

    Ok, entered UEFI, set secureboot mode to custom, accessed the key management menu, and set every option to [load default], or whatever exactly it said, and could then enable secureboot.

    after restarting and getting a "bad configuration" error message from windows, and restarting again, I was able to see that system information now tells me that secureboot is on.

    I shut down, and started back up cold, just to make sure I hadn't broken my operating system doing this. It appears that so far I haven't.

    Should I leave it like this, or is there some configuring I should do? (and if so could you help me out with said configuring)

    It appears that you have now successfully enabled secure boot if you are not getting anymore errors at boot.

    no more errors

    Hopefully factory defaults are good enough. I am pretty far out of my depth with this stuff, and don't know where to begin furnishing my own values to replace those.

    Thank you for assisting me

    question- does secureboot increase the time it takes for a PC to wake from sleep?

    I generally put mine to sleep whenever I am not using it, and it seems like it generally takes anywhere from 5 to 10 seconds to wake up now. It used to be the case that waking it from sleep frequently took next to no time (like 1 or 2 seconds).

    Hello Yu Gnomi,

    It shouldn't make any noticable difference it boot times.

    Double check to make sure that you have "Fast Boot" enabled in your motherboard's UEFI firmware settings, and have fast startup turned on in Windows to see if that may help.

    My motherboard has a utility which tells me that fast boot is enabled and I also have Intel rapid start enabled.

    As for windows, this is the page with my power options - I don't know how to enable windows fast startup, or check to see if it is already enabled.

    Clicking on the link in my post above will help show you how to check Fast Startup. It requires that you have hibernate enabeled though.

    regarding the extra time it takes my PC to wake from sleep I mentioned a few posts back- I have discovered that it starts up just as quick as before if I do not have my Windows phone connected to the USB on the front. So secure boot was never the issue, I have just been leaving my phone connected to my PC a lot recently.
