    Everything worked just as you described. Now have a new box with Windows 8 62 bits and Ubuntu 12.04 64 bits. Great!

    Followed this tutorial to the letter, but easybcd and eufi installations dont work very well I think, cannot boot ubuntu 13.04. Also I dont see the metro bootloader.

    I don’t believe you did a clean uefi/gpt install.

      Same here, I tried many different other tutorials but I think Microsoft messed around with their stuff disabling dual booting for other operating systems.

        Thats not for UEFI he/she was using a MBR disk keep in mind for full UEFI usage you need a GPT HDD not MBR it won’t work!

    Can I use Windows’s Disk Manager in the pc to do that because I don’t have the disk.

    OR

    Is there any other way to create.

      Windows DM is a fairly unrobust and limited tool and it DOES NOT create partition with perfect alignment. At least the one that came with XP and Windows 7 did not and I don’t believe anything has much been changed with Windows 8 DM or even disk part tool. Parted magic although will create partitions with the 1mb alignment and also sector alignment if you so desire.

    hi finid

    I was trying to dual boot linux with windows 8 but I got a problem here. The link below shows a screenshot while installing linux on my system-
    https://www.dropbox.com/s/466izb8bex6m6wu/DSC_0539.jpg
    When I select the free space and choose boot partition as primary then the remaining space becomes unusable. So is it possible to select all the partitions of linux including the boot partition as logical.

      Yes, all Linux partitions can be logical.

          From what I see in the first image you showed, the most likely cause of the failure to boot is that the boot partition is too far from the first sector of the disk, or the start of the disk. A boot partition on a 1 TB HDD located at close to the 950 GB mark is way past the point where the system can detect it.

          If that’s the correct diagnosis, and I think it is, the best solution is to create the boot partition right after the Windows system partition, which means repartitioning and reinstalling both OSs.

            hey i tried googling on this issue nd i found that through grub shell command prompt some commands need to be entered to boot manually or using the linux live cd to fix it. but i am not able to get through with the steps correctly. do u have any idea on this…
            the following imformation was taken from the following site-
            http://tuxers.com/main/instigating-a-manual-boot-from-the-grub-prompt/
            please do give me a solution if possible because reinstalling and repartition is a complete headache

          2. finid

            It is very unlikely any method will solve your problem. I think the boot partition is too far out from the first sector of the disk for any method to help.

            But I could be wrong. Try the steps given in that article that you found or the one given here.

            Hi finid
            You were wrong in ur earlier statement. I finally worked it out by trying boot repair….removed both grub nd installed new one. Only the boot menu is in ubuntu style but thats not a problem for me…
            Thanx for ur help for doing the overall procedure.

    I need some assistance. I followed this guide exactly the way you suggested. Everything is working fine except one small issue. The Windows Dual Boot screen is displaying the old command line Windows Boot Manager instead of the Metro bootloader. I googled about it and tried all the settings but this never changes. I’m at a loss for what could be the reason for this.

    I do sometimes see the Metro bootloader at random but I don’t know what could have caused it to appear. I really need that metro bootloader because my bluetooth keyboard is not responsive in command line or bios for me to change selection. I have to plug in a wired keyboard just for that which is annoying.

    I would really appreciate if you can help me resolve my issue. I have a SSD hard disk on which Windows 8 is installed and a normal hard disk on which Ubuntu is installed.

      I think this is a normal behavior with this really semi dual boot installation procedure.
      You will see the Metro boot loader after booting up with Windows-8, then shutting down, and restarting your computer.
      In other words, the Metro Boot Loader will allow you to switch from Windows-8 to Linux/Unbuntu, not the other way around.

        But I’m not seeing it in Restart either. It happens randomly.

        Do you get the Metro Boot Loader always?

          Yes, I always get the Metro Boot Loader after a full shutdown of Windows-8 then restart of the computer.
          — I get the Windows Boot Manager if I select to boot up Ubuntu (from the Metro Boot Loader) then shutdown Ubuntu and restart the computer.
          — If I select Ubuntu from the Windows Boot Manager, it brings up Grub the Linux boot loader, from which I can select to boot Ubuntu or Windows or whatever is there.

          It is kind of convoluted, but the dual boot works fine and cleanly.
          I have installed Windows-8 Professional VL for x64, and the Ubuntu Linux-secure-12.10 for x64, and of course the latest version of EasyVCD 2.2 (you need to download it directly from Neosmart), all on a newly built UEFI system, with a virgin disk, nothing preloaded on it.

          Maybe disabling Windows “Fast Startup” can help to avoid the random behaviour/appearance of the metro boot loader.
          To get back to metro boot loader from the “old” boot loader I found something in the EasyBCD forum: “…Win 8 > opened easyBCD > Selected “Useful Utilities” > Selected “EasyBCD Power Console” > ran command bcdboot c:\windows > I then rebooted…”
          For me this helped, however choosing Kubuntu 12.10 leaves me with the problem Loonbloom descriped (“…it says that the boot file is either missing or damaged, it mentions the file “/NST/AutoNeoGrub0.mbr” as the file that can’t be read…”). Pressing enter brings me back to metro boot loader where Win8 can be started without problems. Although I completely reinstalled Kubuntu, I can only boot it from UEFI/”BIOS”

    @Wega–> Somehow, your Linux installation is corrupted. You cannot have more than 4 PRIMARY partitions.

    I did this today. After Ubuntu install laptop booted to Grub menu where I could select Ubuntu or Windows 8. For me this is fine even though I like the look of the Windows 8 dual boot OS Select screen more.

      However, if you select to boot up Windows from the Grub menu, boot up Windows then restart your computer, you will boot up to the Windows dual boot select screen.
      I am assuming you did download and used the updated version of EasyBCD 2.2 , and you saved the new settings as described in the last step of the procedure.

    This procedure works well on newly built PC’s if it is strictly followed. Thank you. However,

    1. Your digressions and comments about GPT and the MBR are plainly misleading, and you may want to update and remove them from your text.

    2. The size of the Linux partitions in your tutorial are questionable. In particular, the size of the swap area is supposed to be twice the size of the RAM on your computer. So 8 GB would be a better recommendation.

    Finally got Windows 8 and Fedora 18 to dual boot (I chose Fedora 18 instead of Ubuntu 12.10 because Fedora 18 has better support for full disk encryption when you choose to create your linux partitions manually). Anyway, here’s what I did:

    1. If you bought a computer pre-installed with Windows 8, disable
    Fast boot and Secure Boot (DO NOT change the BIOS from UEFI to
    legacy).
    2. In Windows 8, shrink your Windows 8 partition to free space
    for Ubuntu (or whatever distro your installing).
    3. Insert your Ubuntu 12.10 installation DVD and reboot.
    4. Install Ubuntu
    5. After you install Ubuntu and reboot your computer, you will
    either see Ubuntu’s GRUB menu or boot straight into Ubuntu.
    6. Open a terminal and become root:

    $ sudo -s

    7. Enter the following command to disable os-prober:

    # echo GRUB_DISABLE_OS_PROBER=true >> /etc/default/grub

    8. Find the fs_uuid of the Windows boot manager and write down the
    output from the command (yes, the correct boot manager for
    Windows 8 is bootx64.efi NOT bootmgfw.efi as many people have
    posted here and elsewhere):

    # grub-probe –target=fs_uid /boot/efi/EFI/Boot/bootx64.efi

    9. Probe the EFI boot partion for strings hints search parameter
    and write down the output:

    # grub-probe –target=hints_string /boot/efi/EFI/Boot/bootx64.efi

    10. Create a custom menu entry for Windows 8 in /etc/grub.d/40_custom:

    menuentry “Windows 8 (UEFI)” {
    insmod part_gpt
    insmod fat
    insmod search_fs_uuid
    insmod chain
    search –fs-uuid -no-floppy –set=root
    chainloader /efi/Boot/bootx64.efi
    }

    11. Run grub-mkconfig to generate the GRUB config file:

    # grub-mkconfig -o /boot/efi/EFI/ubuntu/grub.cfg

    12. Reboot and enjoy.

    (Note: if your running Fedora 18, the GRUB commands start with grub2 instead of just grub, e.g., grub-mkconfig in Fedora is
    grub2-mkconfig).

      Sorry, for some reason part of the search command in step 10 got truncated. The full command is:

      search –fs-uuid –no-floppy –set=root here.

        Don’t know if I’m typing something wrong or what. The command is:

        search –fs-uuid –no-floppy –set=root your-search-hints-strings here your-fs_uuid-here
