Once the USB boots, you need to click "Repair your computer" instead of install and then click Troubleshoot -> UEFI Firmware Settings -> Restart. You can use a Windows 10 install disk as an emergency boot disk.
To force the BIOS to appear under these circumstances, you can try using an emergency boot disk, provided that you can either select a boot device at startup or your computer has set an external USB drive as a higher boot priority than its internal storage drive(s). I've had this problem when I had a missing or corrupted bootloader, I got the Windows splash screen and then a blue screen of death. Depending on what you right-click, the context. However, the biggest problems occur when the system POSTs too fast for you to hit a key and then Windows or Linux tries to boot and fails. As part of Windows 11s full aesthetic refresh, Microsoft created a new right-click context menu thats bigger and easier to read than Windows 10s. If your computer can't load an operating system, because it doesn't detect a bootable drive, it will usually pause, beep and give you the option to enter the BIOS, which it will often call "setup." Open the NVIDIA Control Panel by right-clicking on the NVIDIA icon at the bottom right corner of the taskbar and selecting the NVIDIA Control Panel option. Check whether your monitor is in G-sync mode by turning off and again turning it back on. What if you can't boot your OS or hit a BIOS key? While signing in, turn off all other monitors except the G-sync enabled monitor. If you're running a modern version of Linux such as Ubuntu, you may be able to get to the BIOS by typing "sudo systemctl reboot -firmware" at the command prompt.
