    bios has fast boot option not windows 10 ,that's why you don't find it ,and it maybe that you don't have a uefi firmware bios neither ,that's why the win10 repair option doesn't show it.
    andi said it before and ill say it again ,computers have been disabling onboard video as soon as it detects the addin video card ,for a few years now ,so if you di get into the bios you will not find a setting for to dieable it ,,, what you need to do is reinstall win7 and start the upgrade over
    Windows 10 has a Fast Startup option that can make it hard to access the BIOS on boot up. And yes, if you don't have a UEFI BIOS or installed in legacy mode, that boot o UEFI settings option will be MIA. My posts are bit out of sync, didn't read the all the posts in the tread before posting.

    Lots and lots of people hear "Fast Startup" and immediately think BIOS. It might even be called that in some BIOS. In mine its Fast Boot or Fast Bootup, I'd have to go look to confirm. I always leave it on, its never been an issue for me. If you turn it off, you get all kinds of on screen status messages etc that really slow the Boot process down. I have SSD's in my laptop and desktop so the Windows Fast Startup doesn't really give me any benefit. I do a powercfg -h off anyway to kill sleep mode and hibernate and delete the hyperfill.sys file. I never use sleep or hibernate. It also kills Windows Fast Startup. Then I go in and tweak my power settings. One of the gotchas with Fast Startup is your PC never fully shuts down, it goes in a hybrid sleep mode. That's why BIOS access is so hard on boot up. Your not really booting up, your coming out of a sleep mode.

    It is called "Fast Boot". On my desktop with an SSD it adds approx 1/4 second to boot time. It is disabled because I usually need to enter the BIOS at least once a day (device is heavily overclocked and used for hardware testing and benching). All other machines it is enabled. If I need access to BIOS on them I can use the shift+power for UEFI access through windows

    The BIOS "Fast Boot" option, for me, has no effect on whether I can access my BIOS or not. I can get in with it turned on of off. I never turn it off. Turning on Windows Fast Startup on the other hand makes it impossible for me to enter the BIOS on boot up by pressing a keyboard key.

    For one i see this system was not tested to see it can run Windows 10, there are also no updated drivers for Windows 10 on Dell's site

    My XPS8100 is also "not tested" however it upgraded to Win 10 with no problems and nicely runs some programs and printers that are not approved for Windows 10. Of course reinstalling those programs and printers could be a problem later.

    It is just so weird how everyone's unique hardware/software setups impact upon everything else. Windows Fast Startup doesn't stop me entering my BIOS on my testing rig and is therefore enabled

    I'm not sure if this problem has already been solved, but I decided to enable Fast Boot once to see how it went, and apparently it disables USB devices during the POST so I couldn't access the BIOS. I had to reset the CMOS (you can either do this by the jumper or removing the CMOS battery) and it reset my BIOS to default settings which has the Fast Boot option set to Disabled. Although this may vary by BIOS, when my computer started after I reset the CMOS, it gave me a pop-up asking me if I wanted to enter the BIOS, so if my default BIOS settings had Fast Boot enabled, that could be a way to access the BIOS for me.

    Do you have a UEFI Bios or Legacy? If you have a UEFI see post #5

    I can press Esc key on my laptop or F8 on my desktop and access my BIOS Quick Boot menu. That menu will let me boot from a USB thumb drive for that one boot. Even with the BIOS Fast Boot option enabled. The laptop is UEFI the desktop legacy BIOS.
