1: Downloading
To install Debian, you will need to have an ISO file and flash it onto a drive (USB Drive, Flash Drive).
You can choose different flavors of Debian, (Ubuntu, Pop!_OS, Linux Mint, RPI OS) but in this tutorial we will install Debian itself.
Download the Debian ISO here.
If you want to install a different Debian-based system, we have a list of downloads to those here.
2: Flashing it onto a drive
Now, locate the ISO file you downloaded earlier. Now, open rufus.ie and download Rufus.
After that, open rufus. You will have a list of options.
Select the ISO image and your USB Drive and click Start.
3: Booting
After flashing, you'll need to boot from the USB.
Each Motherboard manufacturer has its own key for the boot menu.
You can search for your motherboard manufacturer's boot menu key on Google. We will put here a list of keys.
Dell: F12
HP: ESC
ASUS (and a lot of other brands): Delete

If you want to use the entire disk, choose Guided - use entire disk (as the name says :D)

If the package manager asks if you want to install something from the USB, say no.

Leave the proxy blank. (if you don't have one)
Wait again.
