Can't boot from usb drive for nothing

[Arisu]

Recently i've been having some problems with wifi connection on 20.3, i tried fixing it but eventually it just stopped working completely (the network settings doesn't show any wifi options).

I figured i should install the 21.1 version so i made a bootable usb drive. Problem is, i just have no idea on how to run this thing. Grub just won't show up whatsoever.
I've managed to install the 21 version with the terminal, and yet the wifi problem still continues and it still wont boot from the usb drive.
Already tried pressing F12 and holding Ctrl+Alt and pressing Del, both wont work.

Please help.

Hello and welcome to the forum.

It sounds like you have been in your bios before. How do you get into your bios? Delete, F1, F9, or something else.

How did you make that bootable usb drive?

You plug it in, start the computer, get to your boot menu in your bios, and select the bootable usb drive.

How did you do that?

I never got to manually choose the bios while starting the pc, Mint is the only OS on it.

The bootable usb was made by downloading the ISO, then writing it on the usb drive right clicking the ISO, as demonstrated here: https://linuxmint-installation-guide.re ... /burn.html

You plug it in, start the computer, get to your boot menu in your bios, and select the bootable usb drive.

That's what i've been trying to do, but i just can't access the boot menu, it's the whole problem really.

I followed the instructions on this page: https://www.edivaldobrito.com.br/como-a ... ntupgrade/

What brand and model of laptop or desktop are you using?

You can try the following ...

• Read the manual and be certain you are using the correct keyboard key to enter the manual.
  Remove the boot drive from the motherboard and try to boot into the BIOS.
  When booting do not have any USB devices attached to the computer.
  Read the manual and see how to reset the BIOS. Have a flashable BIOS firmware on hand.

You said the computer came with Linux on it so was this a turnkey system you bought? If so, the manufacturer may have, for their own sanity, disabled the USB boot on the PC or laptop. Once you do get into the BIOS be certain to enable that and to look for an option that will display the full boot message or an option that will say to display the boot prompts for a certain amount of seconds. If there is a time for the prompt then set it for something like 8 seconds, this will give the BIOS time enough to display it during the boot process and time enough for you to react to it. People that set it for 1 second may shorten their boot times but they also make it difficult to get into the BIOS as the prompt ends before they can respond to it.
