hello everyone, i hope you are all doing fine! everything has worked for me up until so far,where i am trying to boot Ubuntu from my bootable flash drive. there's a big problem however - my BIOS requires you to use the down arrow key to select "booting from USB" but my down arrow key doesn't work at all. i've tried using the up arrow key to see if that would take me to the bottom of the boot menu, but it doesn't work. i've considered a usb keyboard but i am not sure it would work. i've heard something about "Legacy USB" but i'm not sure if that is going to help with my issue of the keyboard? may i have some advice? thank you!
