    General UEFI Question


    UEFI is a real pain in my butt. I've done extensive reading. I understand (I think) secure boot. I've successfully made a UEFI boot usb windows install disk. I know how to get to access UEFI interface through Windows 8/8.1/10. What I can't find an answer to is how to get to the UEFI interface when Windows will NOT boot. Fast boot makes timing when hitting any sort of key (f2,del,f10 etc) an impossible task. I've tried shift+power and that doesn't work. So someone please tell me how I can access UEFI to turn off secure boot or select my boot order. I have spent many hours on this and I'm about to wear out my power button.

    Also, is there a way I can take a 64 bit Windows 10 recovery drive created on a bios based system and convert it to a UEFI recovery drive using Rufus.

    :)

  2. General question

    Thank you. I do agree with your view that there are many here who should not attempt complicated operations. I'm hoping that by stressing excellence it will attract more enthusiasts who no longer have their own stellar forums as in Windows 7. Clearing
    the complainer rabble after Upgrades should help settle things down to a better learning experience for all levels.

  3. General question

    I've helped about a hundred thousand consumers in Forums for 7+ years and every one who cooperated got their fix. Thousands (for example) had complicated partitioning problems which a shop wouldn't begin to figure out and would just recommend reinstalling,
    but by reading a screenshot of Disk Management I have walked them through complicated partitioning changes like conversion to Basic without file loss, jumping partitions over each other while resizing them all, etc. also without a single failure using the
    flawless tool
    Partition Wizard
    . During the long conversion to UEFI BIOS' I personally helped about 10,000 consumers struggling with buggy early firmware to get Windows 7 installed, until gradually newer firmware sifted out UEFI install problems to near-zero.

    As to MVP's hewing the MS line, I spoke out passionately against what I considered the push to smother Windows 7 in its crib in favor of the new Store-based business plan starting with Windows 8. We were able to get the Windows 7 reinstall ISO's put back
    up for another five years so that millions could get the best install possible following

    Clean Reinstall Windows 7
    which popularized Clean Installs for the masses, backed down OEM's from refusing to Support them, and caused MS to drop a built-in antipathy to them and ultimately automate in Windows 10 as a Reset saving nothing.
    At no time did I feel I could not speak out even when it was critical of MS. In fact my MVP lead during this time JP Clementi encouraged me to speak passionately and brought me and other MVP's in front of a focus
    group of top MS execs to explain where we felt Windows 8 had gone wrong with consumers, which directly led to the consumer-based Insider program helping develop Windows 10.

    I can count on one hand the times I've painfully read MVP advice being wrong, usually when one of us tries to veer out of our specialty. Now as the Consumer MVP program is being reformed with our input, I'm advocating strongly that the standard be that
    MVP's are absolutely top experts in their field.

    To my knowledge and that of several dozen I've asked, there is no higher award in the tech field. It is an honor that has propelled me from an enthusiast to a constant pursuit of excellence during an average 5-8 volunteer hours spent in forums daily.

    On most motherboards, you can press a key to select which device boot from. It's usually F12. If FastBoot is a problem, turn it off.

    Clear the CMOS. Also known as reset the RTC (real time clock). That's the advice from my motherboard manufacturer (Asrock).

    Easy on a desktop PC (jumper or pushbutton). Usually harder on a laptop. (May have to find and unplug the CMOS backup battery, as well as removing the main battery.)

    You turn it off all the time.

    go to power options then click on "Choose what the power buttons do" and then click "change the settings
    that are currently unavailable". Now you can stop fast startup

    Not especially helpful if you can't boot into Windows (post #1).

    You do this in the BIOS so don't need windows loaded.

  11. to access uefi follow these instructions, turn off fast boot in the bios (you cannot access the bios normally in fast boot).

    Access UEFI bios through your desktop environment:

    • Click the Start
      General UEFI Question [​IMG]
      menu
      and select Settings.
    • Select Update and Security.
    • Click Recovery.
    • Under Advanced startup, click Restart now. The system will restart and show the Windows 10 boot menu.
    • Select Troubleshoot.
    • Choose Advanced options.
    • Select UEFI Firmware Settings.
    • Click Restart to restart the system and enter UEFI (BIOS).

    Surely even with fast boot on you can still access the bios from a cold start (not a restart) by pressing F12 or DEL or whatever your mobo requires? I can anyway.

  14. Shut down pc/laptop. press and hold down f2. Restart pc/laptop while still holding f2 down, release when you see bios. enjoy.

    note: IMPORTANT. DON'T BE REFLASHING THE BIOS FOR THIS. warned.

  15. If it's a laptop, power down, remove the battery, unplug the power pack, press and hold the power button for say 10 seconds. Then plug everything back in and power up, pressing your BIOS access key. If it's a desktop PC it's the same only no battery to remove. This should kill what ever hibernation state your in and give you an actual cold boot.
