    Re: Booting Windows only if USB flash disk is plugged in.

    Fastboot is off in Windows and in UEFI/BIOS. SecureBoot is also off in UEFI/BIOS.

    As mentioned before, I removed the Drive completely to test if it is causing that issue and I still got the same errors I sent it here before.

    As you can see in the errors. https://www.dropbox.com/s/nzczfkb8kv..._0001.JPG?dl=0

    Does this site have chat? Can I get live assistance to eliminate all problems because it seems like we are not moving ahead? I can boot up the system while live on camera.

    Windows has no issues booting at all.

    But it is not seeing your NTFS partitions. And that is a Windows issue.
    Are you sure Windows fast start up or hibernation is off.

    Fast Start up off (always on hibernation), note that Windows turns this back on with updates, SHIFT + Shut down button

    Re: Booting Windows only if USB flash disk is plugged in.

    I am 100% sure about fast startup. It is off for sure. I also mentioned that I removed the drive from the laptop and still did not work. It only works in legacy support mode. I checked it several times. Even before the last post. It is off.

    But I don't know about hibernation. I don't use it.

    I never new it can be turned off.

    Do I have to turn it off?

    That is mine on win8.1

    The below is some information about the partitions on my drive. I did not create them. They are created by Lenovo.

    Standard set of Windows partitions for UEFI/gpt.

    You need hibernate off also.

    Disabling hibernate did not work either.

    Anyway, I posted a request with Supergrub Forum on Github.

    If it still cannot be solved then I will will just close the thread.

    Re: Booting Windows only if USB flash disk is plugged in.

    I did not get a response from any of the other forums on booting SuperGrub errors on UEFI.

    Even if it did work. It would still not be convenient. Unlike my other system (Legacy support BIOS running Windows 7) where I am using it in every boot up. The solution for that can be found in a link in the 1st post of this thread. On the UEFI system it never remembers the boot order, so each time I have to go to boot menu. To access the Boot Menu I have to press a small button on the side of the laptop, unlike in old systems where all these things where much easier. It also has an issue detecting the attached USB so I would have to keep turning it off and pressing the small button on the side. I have to keep on doing that over and over until it detects the connected USB.

    So over all the solution is not hassle free.

    I think the best solution for this is to install the system with MBR instead of GPT. Maybe one day I will do that and test it on legacy support and update here. But I am not planning to do so.

    Even if it work it won't be convenient because it does not remember the boot up settings mentioned above in this post.

    Re: Booting Windows only if USB flash disk is plugged in.

    UEFI boots external devices from /EFI/Boot/bootx64.efi. Which is usually shimx64.efi with Ubuntu and whatever .efi file Windows uses to boot with. Not sure Windows can boot an internal install from external device.

    If you have a standard entry like "grub" or "ubuntu" in UEFI for an external drive, it will forget that entry when device is unplugged.

    I have put a full install of grub into a flash drive and manually edited grub to loopmount ISO. So it can be customized, but with a grub install without full Ubuntu everything is manual.

    Re: Booting Windows only if USB flash disk is plugged in.

    I recently upgraded Windows 7 to Windows 10 on the system running with Legacy Support.

    The same process in the link of the 1st process dedicated to that method has worked well.

    So in conclusion. Install Windows on Legacy support if possible to get this secure way to work.
