    dual boot efi windows and efi linux

    Hi,

    I have a new x64 HP computer that supports EFI. I installed windows 7 pro using a EFI bootable usb thumb drive. Windows 7 works great. Now I want to install Ubuntu Lucid Lynx also by booting from a EFI bootable usb thumb drive. Unfortunately Ubuntu doesn't seem to support EFI booting for installation. So my plan is to boot the ubuntu installer using legancy mode and download grub 1.99 and do the following:
    export EFI_ARCH=x86_64 ./configure --with-platform=efi --target=${EFI_ARCH} --program-prefix="" make
    sudo mkdir -p /mnt/EFISYS # if the mount-point does not exist sudo modprobe dm-mod # required to make grub-probe stop complaining sudo mount -t vfat -o rw,users /dev/sdc1 /mnt/EFISYS sudo mkdir -p /mnt/EFISYS/efi/grub
    cd <grub2_compiled_source_dir>/grub-core ../grub-mkimage -O ${EFI_ARCH}-efi -d . -o grub.efi -p "" part_gpt part_msdos ntfs ntfscomp hfsplus fat ext2 normal chain boot configfile linux multiboot sudo cp grub.efi *.mod *.lst /mnt/EFISYS/efi/grub
    sudo touch /mnt/EFISYS/efi/grub/grub.cfg

    The above is from https://help.ubuntu.com/community/UEFIBooting but doesn't cover exactly what I am trying to do.
    That should be enough to get the system to boot the thumb drive using EFI right?
    Once I get the system to EFI boot how should I partition the Linux system? I have:
    sda - window 7 x64 sp1
    sda1 - windows 7 EFI partition
    sda2 - msr Microsoft reserved partition
    sda3 - windows 7 install

    sdb - Linux blank hard drive

    sdc - usb thumb drive

    Does Linux need its own EFI partition? Can it share with sda1?

    Thanks

    Re: dual boot efi windows and efi linux

    I have not done any of this, but since I hope to soon I have saved some links.
    One bug in grub is that it overwrites the efi partition and reformats it to fat16. It should do neither. So be sure to make a backup of the Windows efi partition so you can restore that and reset to fat32 so Windows works.
    As I understand it, you just about need the very latest version of grub to really work with UEFI and even then may have to work around some bugs they still are fixing.

    Re: dual boot efi windows and efi linux

    The good news is my computer can EFI boot from my linux thumb drive. I used the directions at
    https://help.ubuntu.com/community/UEFIBooting
    The important part was to rename the /efi/grub directory to /etc/boot and rename grub.efi to bootx64.efi
    I don't think HP has all of the bugs worked out of their EFI bios yet. It should have worked without renaming anything.

    However I having difficulties writing a valid grub.cfg. So far all I can do is boot to a grub prompt.

    Did you review the Arch site with UEFI sub-heading:
    https://wiki.archlinux.org/index.php...r_UEFI_systems
    and this:
    UEFI systems


    It seems to go over grub2 and UEFI pretty well and does not look like much is Arch specific.

    Re: dual boot efi windows and efi linux

    Thank you for the Arch Linux link it solved my grub.cfg issue.

    I now have a EFI booting USB thumb drive of Ubuntu. During boot I get a fair amount warnings. I also get a kernel panic when I try to reboot.
    I am using Ubuntu 10.04 LTS, Linux kernel 2.6.39.4

    I am not going to install Linux to the second hard drive as the above bugs haven't been fixed yet. I hope they get fixed for 12.04 LTS.

    Re: dual boot efi windows and efi linux

    I managed to install Ubuntu 10 LTS on my system using EFI. I started the installer and selected the option to manually create the partition layout. I used the following layout on my 250GB drive:
    200MB /dos fat32
    240GB / ext4
    8GB swap

    Before I clicked on install I selected advanced and deselected the option to install grub. I then clicked on install. Everything installed fine. I then opened a terminal and copied my grub2 configuration from my usb thumb drive to /target/dos
    cp -R /cdrom/EFI /target/dos

    Here is my grub.cfg
    # Config file for GRUB2 - The GNU GRand Unified Bootloader
    # /boot/grub/grub.cfg

    # DEVICE NAME CONVERSIONS
    #
    # Linux Grub
    # -------------------------
    # /dev/fd0 (fd0)
    # /dev/sda (hd0)
    # /dev/sdb2 (hd1,2)
    # /dev/sda3 (hd0,3)
    #

    # Timeout for menu
    set timeout=5

    # Set default boot entry as Entry 0
    set default=1

    # Set default color
    set color_normal=white/blue

    # (0) Original
    menuentry "x64 Linux" {
    set root=(hd1,1)
    linux /vmlinuz-2.6.39.4 root=/dev/sdb2
    initrd /initrd.img-2.6.39.4
    }

    # (1) custom kernel
    menuentry "x64 Linux custom kernel" {
    set root=(hd1,1)
    linux /vmlinuz-3.1.6 root=/dev/sdb2
    initrd /initrd.img-3.1.6
    }

    # (2) Windows
    menuentry "Windows" {
    set root=(hd0,1)
    chainloader (${root})/EFI/Boot/bootx64.efi
    }

    So I have a pretty good system now. I just need to fix the clock in Linux. When I boot back into windows my clock is off by my timezone -5 hours. I also need to write a xorg.conf, the default screen resolution is way too small and kandkresize doesn't have any other resolutions than the highest resolution the monitor supports. I prefer 1280x800 instead of the 1440x960 that Ubuntu is using. Finally I need to figure out how to boot Ubuntu without having X auto start. It used to be easy, edit /etc/inittab and change 5 to 3. I know Ubuntu is using upstart but there is no /etc/event.d directory that the documentation says should be there.

    Since my BIOS doesn't allow me to specify which hard drive to EFI boot from I might move the grub files form the second hard drive to the first to enable grub2 to dual boot without me having to press F9 at exactly the right moment.

    Re: dual boot efi windows and efi linux

    We are trying to test a new bootinfoscript to verify that it has improvements. One is to correctly identify the efi files. Can you run this and post the results.txt? Thanks.

    http://ubuntuforums.org/showthread.php?t=1897412
    Code:
    wget -O bootinfoscript 'http://bootinfoscript.git.sourceforge.net/git/gitweb.cgi?p=bootinfoscript/bootinfoscript;a=blob_plain;f=bootinfoscript;hb=HEAD'
    
    chmod a+x bootinfoscript
    Then you can run it

    sudo bash bootinfoscript

    Re: dual boot efi windows and efi linux

    Thank you for the detailed instructions. I appreciate it. Attached is the results.txt file.

    Please note that the /grub/grub.cfg is NOT the grub.cfg that I use. The grub.cfg I use is in /dev/sdb1/EFI/Boot/ and can be found in my previous posting.

    The /dev/sdb1/grub/grub.cfg came when I did a apt-get install grub2 which is rather pointless as all of the files have to be in /dev/sdb1/EFI/Boot/ for the system to boot.

    Thanks,

    Re: dual boot efi windows and efi linux

    @ Jake42
    Can you download the last version of BIS and run it again?
    The Boot Sector type should now display something else than "Unknown" (Paste that part).
    Code:
    sda1: __________________________________________________________________________
    
        File system:       vfat
        Boot sector type:  Unknown
        Boot sector info:  No errors found in the Boot Parameter Block.
        Operating System:  
        Boot files:        /efi/Boot/bootx64.efi
    Get last development version of Boot Info Script:
    Code:
    $ ./bootinfoscript --update bootinfoscript-git
    $ chmod a+x bootinfoscript-git
    Change log
