Installing Ubuntu on a Pre-Installed Windows 8 system

I just bought a new computer and it has windows 8 but I don't like windows 8 and wanted to use ubuntu 12.10 and am wondering if this is possible to do because of UEFI. It is an hp pavilion p6-2376.

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.

    
I managed to install 12.10 with UEFI. As for 12.04, you would have to use legacy boot. –  Melon Dec 27 '12 at 22:24
    
is your computer 32 or 64 bit? I am not sure but I think 32 bit ubuntu does not have EFI support, yet. Also 12.10 has it and 12.04 not. –  don.joey Dec 27 '12 at 22:26
    
My computer can support both 32 and 64 bit. I will download the 64 bit and burn it to a dvd and try it. Is there something that I have to do because my computer already has windows 8 installed or can I just boot to the ubuntu cd and overwrite windows 8 –  user117106 Dec 27 '12 at 22:48
    
Try using a USB stick (faster than CD/DVD), but initially run Ubuntu alongside (using LiveCD) to test. –  david6 Dec 27 '12 at 23:02
    
I did the live but I just get a black screen. I tried the 64 bit. Can someone help me with this and why its happening? –  user117106 Dec 28 '12 at 2:13

UEFI is not an impediment to installing Ubuntu 12.10. Contrary to one comment, it's not an impediment for 12.04, either, or even several earlier versions -- but Ubuntu's UEFI support has improved with recent releases, so it's better in 12.10 than in 12.04.

That said, you may need to do things differently than you would on a BIOS-based computer. Windows 8 machines also usually ship with Secure Boot enabled, which can cause problems. (This is an area in which 12.10 is supposedly better than 12.04, but I've seen a few problem reports even with 12.10, so you may have to disable Secure Boot in your firmware.)

I've heard that the image file used to distribute Ubuntu boots successfully in EFI mode from CD, but not when burned to USB drive. I ran across instructions for adapting it recently, but I didn't save the URL, so I'm afraid I can't point you to it.

I've read that with secure boot enabled, Ubuntu will install but may still fail to boot.

To disable UEFI secure boot:

go to the Charms Bar in Windows 8 and select Settings > Change PC Settings > General > Advanced Start Up. On the next screen select Troubleshoot > Advanced Options > UEFI Firmware Settings (this option is available only on new Windows 8 machines). (from: http://www.pcworld.com/article/2015107/downgrading-from-windows-8-to-7-what-you-need-to-know.html?page=2)

On my HP Pavilion laptop, I run Ubuntu in VMware Player since when installed under Wubi or to a partition, the fan runs non-stop and the cpu gets too hot.
