This question already has an answer here:

I recently purchased a Toshiba laptop, that had Windows 8 pre-installed. As Windows 8 is awful, I decided to attempt to dualboot Ubuntu. Did some research, and found out that it is not as simple with UEFI enabled. If there is some way to keep UEFI enabled (unless it is completely pointless) I would love a step-by-step tutorial. Either way, I could really appreciate some help as I have seen multiple methods, all of which are different. If you require any more information about my system, feel free to ask.

Thanks in advance.

BTW I am a first time Ubuntu installed, so like I said STEP-BY-STEP instructions would be appreciated.

Seth, like I said I haven't installed Ubuntu on a system before, so I haven't even gotten to that point.

UEFI is not completely pointless, but you have to turn it off to install Ubuntu 12.10 (32 bit at least) I'm pretty sure. And computers didn't used to have it, but it is safer. I did this recently, I think it was in the boot menu.

STEP 1: Seth is correct. If you want to install Ubuntu 12.10 in 32 bit you have to switch from UEFI to Legacy at least temporarily. He provided a great guide that was upvoted 46 times. Do that first. Once you've turned off UEFI you can install Ubuntu.

ALTERNATIVELY, if you have a 64 bit system you can follow this guide to installing Ubuntu in UEFI: https://help.ubuntu.com/community/UEFI

STEP 2: Did you put Ubuntu on a CD/DVD or USB? You need to make a bootable CD/DVD or USB with Ubuntu. There are a million great guides online to do this.

STEP 3: Change your boot menu order so that when you turn your computer on, it reads the usb and boots from that instead of from your harddrive. This means you'll be running your OS from your USB or CD as you install it. This will also be included in pretty much every installation guide.

I am infact on 64 bit, so first I disable UEFI? This won't change anything important in windows will it? –  user1446371 Mar 9 '13 at 5:36
    
I put Ubuntu on a USB using Universal USB Install, and it all went well. So now I go ahead and disable UEFI? –  user1446371 Mar 9 '13 at 6:01
    
I installed Ubuntu 64 bit on a UEFI system by disabling it, but it says in the link that you can do it without disabling UEFI on a 64 bit system. I've never tried this personally, but if you're concerned than you could go that route. It's just a security measure they added in, it won't change anything. –  NicBaird Mar 9 '13 at 6:04
    
So I basically just disable UEFI then I can just follow a YouTube tutorial for installing it and it should be fine? –  user1446371 Mar 9 '13 at 6:13
