Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system

I want to install the ubuntu 12.10 or 12.04 desktop for my new pc.

steps: I created a bootable usb, config the bios to boot from the usb drive. press "try ubuntu before you install it" ubuntu 12.10 and 12.04 on my new desktop, it is failed.

Can anyone give me some advice?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Pressing "Try Ubuntu before you install it" does not install it. You need to select 'Install Ubuntu 12.x' instead. – Mochan Jan 13 '13 at 11:45
Why is it failing, can you describe where are you getting stuck or what do you see on the screen? Any error messages or faults? – Bruno Pereira Jan 14 '13 at 10:33
@Mochan Or select Try Ubuntu and then run the installer from the desktop. – Eliah Kagan Jan 14 '13 at 23:57

What options are there when booting Ubuntu from a USB or CD?

You have two options when booting from a bootable USB or using a LiveCD.

The first option is:

Try Ubuntu

Try Ubuntu

The Try Ubuntu option allows you to try Ubuntu without permanently installing it and altering your system. It creates a environment, run by the files on your CD/USB and using the hardware on your computer. While in this state, your hard-disk is not affected and no changes are permanently made to your system.

The second option is:

Install Ubuntu

Install Ubuntu

The Install Ubuntu option permanently (unless you want to remove it) installs Ubuntu onto your computer, and from that point on will use your hard-drive to save files and to operate off. If you choose to dual-boot with Windows or OS X, you are able to choose which one to start at the boot of your computer.

Which should I use?

  1. If you are looking to test Ubuntu, you should:

  2. If you wish to permanently install Ubuntu, you should:

    • Choose the Install Ubuntu option, and
    • Run it alongside (dual-boot) Microsoft Windows, Apple OS X, or another OS you have installed, or
    • Replace your old OS with Ubuntu. Please not that this will remove all files and data on the other OS.

Depending on what you want to do, you must choose the right option!

Good luck!

i already tested "Try Ubuntu" option but failed by a bootable usb. Is there any other options ? thanks – michel Jan 13 '13 at 15:01
Do you want to install Ubuntu, or just try it? – Mochan Jan 14 '13 at 0:12
This has nothing to do with what the user is complaining about. pretty sure he knows how to boot either to try or install, but something is going wrong. – Bruno Pereira Jan 14 '13 at 10:32
to Bruno Pereira when i choose try ubuntu before install it, there is only black screen with blinking underscore....then it stop blinking.... – michel Jan 14 '13 at 11:47
