    Cant access BIOS in Legacy mode


    So last weekend I was trying to install Tails OS on a usb so I can play around on the dark web. Before when I could get to my bios I mistakenly changed it to legacy mode. Now nothing I seem to try wont let me access the bios. Here are a few thing I've tried so far.

    -Using the MBR to GPT coversion utility in cmd. But the conversion failed for some reason.

    -Holding shift while restart, going to troubleshoot, advanced options but there is no option for UEFI settings

    -Remoming the CMOS battery from my mobo which didnt seem to do anything.

    -Downloading AsRock restart to UEFI for my mobo. Which DOES get me to BIOS but my mouse wont move at all.

    -Using AOMEI partition assistant to convert from MBR to GPT but gave an error.

    Now AOMEI partition assistant said something about my boot partition and system partition being on seperate drives. I'm not quite familiar with fiddling with drive partitions. My boot part in on my C: and my system is on my D: I beleive. Is there any way to resolve this without a Win 10 reinstall? I do have a usb with Win 10 ready to go in such a case. By the way my Windows version is 1909 OS build 18363.900. Thank you for your time.

    :)

  3. access BIOS settings in Win 10

    I have an 8-year old computer running Win 10. I need to access the BIOS settings. It used to be the holding down the F2 key during startup would bring up the BIOS screen in Windows computers. But this no longer works. A web article listed a complicated
    series of steps leading to a reboot . . . but still no access to BIOS. Any suggestions?

    Accessing BIOS menu

    How do I access the BIOS menu when none of the keys at the blue logon screen will function to get to the BIOS? I have also tried going through the Recovery and restart mode in Settings under Update and Security but there is no option to change the UEFI
    firmware (as my disk is in legacy mode). I also tried Troubleshooting under Recovery but none of the listed options (F1 through F9, not F10, nor even Enter) is active.
