Can I install Ubuntu as the only OS on a new Windows 11 pc without first setting up Windows

system-installation

I have bought a cheap new PC which I hope to put Ubuntu 24.04 or an official flavor as a sole operating system. The PC is an Acer XC-840 manufactured in September 2022 and still in box unused. Spec Intel N4505 processor ,4GB DDr4 Ram, 256 GB SSD , Intel UHD graphics , Bios R01-A2 . Hopefully this is able to run Ubuntu . I have never installed on other than very old computers and would like to know what I need to do to avoid failure . Do I need to run Windows first or can I Boot from a USB with Ubuntu ISO on and just select install using whole drive without disabling secure boot or making other changes beforehand ? As is probably obvious I am very much a beginner with Linux and would appreciate any available guidance.

To answer the question in the subject line: Yes, as long as you already have a bootable media. On Acer computers, the F12 key during system initialization will give you a boot menu from which you can select your bootable media. Then, you can Try Ubuntu before you install it to ensure everything works with your hardware.

If you don't have a bootable media, and no other computer from which to create one, you can use your Windows 11 installation to create it. Setup the Windows11 OS minimally, including an Internet capable network connection. Then, follow the instructions to create the media.

During installation, you will be given the option Erase disk and install Ubuntu to reclaim all your drive space for a clean and full use of your storage by the Ubuntu OS.
