    Exclamation BIOS and boot menu won't open and Windows missing after Ubuntu dual-boot

    Hey everyone,


    I recently tried to set up a dual-boot with Ubuntu alongside my existing Windows 10 installation. Unfortunately, I'm running into some major problems:



    • BIOS Inaccessible: I can't access my BIOS settings at all. The usual keypresses during startup aren't working.
    • No Boot Menu: I can't select a different operating system at boot.
    • Missing Windows: It seems like my Windows installation might be gone, as Ubuntu loads immediately on startup.


    I've tried finding fixes online, but my laptop seems determined to make things difficult. Some websites suggested giving this forum a try, so here I am hoping for some tech wizardry!
    Has anyone else experienced this after a dual-boot? If so, I could really use some troubleshooting tips to get my Windows back and make my BIOS reappear. Thanks so much!

    As you can access Ubuntu, open a terminal and enter:-
    Code:
    sudo systemctl reboot --firmware-setup
    While in your firmware settings, disable Secure Boot, Fast Boot , TPM and other security features.
    No Boot Menu: I can't select a different operating system at boot.
    Possibly Windows 10 was hibernating when you installed Ubuntu?
    Boot Windows 10 via your PC boot menu and disable hibernation i.e. fast start up

    Windows will be added to grub if it is not in hibernation state.
    Reboot into Ubuntu, open a terminal again
    Code:
    sudo update-grub
    Any joy?
