    Just a quick update. I decided to compile my own grub2 bootloader and have managed to boot my backtrack 5 usb in uefi mode.

    Though when I do, grub tells me "error: no suitable video mode found. booting in blind mode!" Soon after, I get a garbled screen, but I can tell that backtrack was loaded.

    I will find a way to resolve this issue eventually.

    The following is my grub.cfg. Please replace the set root= and UUID values with values that are appropriate for your system.

    default=2
    timeout=30
    # terminal console
    gfxmode=640x480

    set menu_color_normal=yellow/blue
    set menu_color_highlight=blue/yellow

    menuentry "BT5R2 3.2.6" {
    search --fs-uuid --no-floppy --set=root 6808-7BF1
    linux /vmlinuz-3.2.6 root=UUID=aa512382-97d8-4bca-af30-f38fa6a166ac
    initrd /initrd.img-3.2.6
    }

    menuentry "Windows 7" {
    search --fs-uuid --no-floppy --set=root 4896-78D2
    chainloader (${root})/EFI/Boot/bootx64.efi
    }
    I like the bleeding edge, but I don't like blood loss

    I read up on some documentation about EFI boot loaders here: Managing EFI Boot Loaders for Linux.

    I have a basic understanding of partitions in linux too.

    My EFI partition (ESP?) is /dev/sda1. Using the command "mountvol Z: /s" in Windows to see my EFI partition, My bootx64.efi file is located in Z:\EFI\Boot.

    Here is my, "setup:"

    Windows 7: installed on Hard drive
    Ubuntu 12.10: installed on one flash drive
    Backtrack 5 R3 Gnome 64 Bit: installed on another flash drive

    So where should I copy the EFI folder from the Ubuntu 12.10 iso to? I suppose I would copy it to my ESP partition, overwriting my old bootx64.efi.
    However, once copied, there is no grub.cfg or any of the grub .mod files in my ESP partition.

    My question is, should i be copying anything over to my Backtrack USB? Because at the moment, when I copy the files over to my /dev/sda1 (EFI) partition and create a grub.cfg in the same folder as bootx64.efi and grubx64.efi, nothing noticable happens when I attempt to boot my BT thumb drive.

    I would prefer to have all of my GRUB2 files on my ESP partition. Rob Smith from the site I linked says this is the best way to configure GRUB2.
    Sorry I have been offline for awhile. rename the existing EFI folder on /dev/sda1 to winefi. Copy the EFI folder from the to /dev/sda1. This is the contents of my /EFI/BOOT folder:

    The mod files might be elsewhere on the CD or they might be compiled into bootx64.efi. Use the grub config I posted in the above message.
    I hope this helps.

    I know it's just temprorary solution but you will turn on back track. Download Virtualbox and you can use all tools from backtrack. But just like i said it's only temprorary solution if you need back track now. you can't instal backtrack using virtualbox
    sorry for my bad english

    I just bought a new HP computer and it supports UEFI booting. I installed windows 7 pro 64 bit using UEFI by booting from a UEFI enabled windows 7 pro usb thumb drive. I am now trying for a UEFI booting BT5R1 install. The first problem is my BIOS EFI issues and I have already contacted HP about this. I have 4 Windows Boot Manager entries in my EFI menu and I can't get rid of them I also can't boot a non UEFI thumb drive anymore.
    The next issue is the isos don't support UEFI. The final issue is the Ubuntu installer screws up the existing UEFI partition.

    I realize that the BT developers didn't write the installer or syslinux or even grub2. I am only asking that they and everyone else help pester the Ubuntu people to get these problems fixed so the next version of BT can be booted by both UEFI and legacy systems. UEFI is the future and the sooner these issues get fixed upstream the sooner the BT developers can take advantage of them.

    The bugs can be found here:
    UEFI bugs:
    Deletes Windows efi partition
    Installer should not format an existing EFI System Partition
    https://bugs.launchpad.net/ubuntu/+s...fi/+bug/769669
    EFI SYSTEM PARTITION should be atleast 100 MiB size and formatted as FAT32, not FAT16

    ctrl-x does not work in grub-efi

    grub-update fails to detect windows bootloader on a uefi system
    https://bugs.launchpad.net/ubuntu/+s...b2/+bug/807801

    Please add yourself to these bugs so we can get them fixed.
    Thank you.
    Bug??????? Bugs??????...It seems to me like there are people trying to block installation of free OS like linux.

    It is not a Bug....One thing is for sure, and you can bet on it, Linux World will succeed, they will work that "small" setback out sooner than later...

    That is my very personal point of view...But defenetly is not a Bug....

    And it shows that not only you, but so many people everywhere are irritated at this issue, the so called Secure boot...mmmmmm.

    Remember people, BT5 exists because of linux and it is free, yes, BT5 is free to the people, you do not have to pay a cent...It is the product of many people working real hard to put this exquisite distro at your reach, free of charge..

    Luck.
