    Question Trouble Installing Ubuntu 12.10 to Dual Boot with Windows 8

    I just recently purchased a Gateway DX4870-UB318 Desktop. It has Windows 8 running on it with 1TB hard drive, 8 GB RAM and an i5 and I am trying to install Ubuntu 12.10 as a dual boot option.

    I tried using the Wubi installer but it complained I was missing a file, so I put it onto a USB and installed it that way. Everything seemed to go OK, however it did not detect that I had Windows 8 installed during installation but instead said that 'No operating systems were detected...'. I decided to just partition the hard drive myself and after partitioning and installing Ubuntu 12.10 I restarted the computer when prompted. When everything rebooted it went straight to Windows 8 and I cannot get Ubuntu to boot at all.

    I downloaded EasyBCD for Windows 8 and it finds my Ubuntu partition. When I set that Ubuntu as the 'default' in the 'Edit Boot Menu' and reboot, it prompts me what OS I want to start with but the only option is Windows 8.

    I've been trying to get this installed for a couple days now and any help would be much appreciated!

    Have they updated EasyBCD to work with UEFI. A while ago it did not.

    Did you install the 64 bit version of Ubuntu? And did you install in the UEFI mode. When you boot your flash drive installer, it should give two choices, one UEFI and the other BIOS/legacy/AHCI or whatever. Only the UEFI option will work if you have Windows in UEFI and Windows 8 will be UEFI with secure boot if pre-installed.

    If you did install the 64 bit version in BIOS mode you can convert to UEFI mode with Boot-Repair. You uninstall grub-pc and install grub-efi and then in UEFI/BIOS choose to boot Ubuntu. Grub also has a bug in creating a boot stanza to chain load to Windows, but again Boot-Repair can also add a correct boot for Windows.

    Post the link to the BootInfo report that this creates.

    From my understanding the new EasyBCD 2.2 does indeed have UEFI support, however I should mention I am new to installing my own OS and do not completely understand what UEFI is or what I need to do in order to comply with it?

    I did install the 64 bit version of Ubuntu. I do not know if I installed in UEFI mode, can you help me out with exactly how to do that because I did not see that option when I used by boot installer (Universal-USB-Installer-1.9.16). Do I need to use a different flash drive installer?

    I have seen the Boot-Repair mentioned elsewhere but, this may be a dumb question, but how do I use that utility when I can't get to my Ubuntu installation? That is just a Linux utility, correct? Or do I install those utilities while just running Ubuntu from a flash drive?

    I apologize for the dumb questions and really appreciate your help!

    I ran the Boot-Repair from Ubuntu and the results are here (this is after I deleted the partition I attempted to install on): http://paste.ubuntu.com/1376493/

    Here is an update from Boot-Repair after after I attempted to install Ubuntu 12.10 again: http://paste.ubuntu.com/1376518

    After running Boot-Repair I now can't boot from anything on the hard drive but only from my flash drive. When I go to click install in Ubuntu it detects the other Ubuntu 12.10 installer but it now appears I've screwed something up with Windows 8.

    Ran Boot-Repair again and back to kind of back to where I began. It prompts me on startup for the OS I want to boot to and the only options is Windows 8.

    Since your computer already had win8 in UEFI, you need to install ubuntu in UEFI too.

    That means:
    1. It has to be the 64bit version since the 32bit doesn't support UEFI.
    2. When you boot the cd or usb to install, you have to boot the UEFI device.

    On UEFI systems you will have two devices for the dvd-rom and for bootable usb sticks: one for the older legacy mode, and the other for UEFI mode.

    You have to boot the UEFI device for ubuntu to install in UEFI mode. Be careful to make the correct selection when booting, and it should be fine after that.
