    Question Can't boot from USB

    Hello guys! I'm new to Backtrack, really new, and I was wondering if you could help me with this issue. I tried to get Backtrack bootable from a USB, I did it as it says on the wiki, I tried both ways actually, and none worked. I managed to do the whole process just as the guide says, but when it's meant to boot there's a message saying "Operating system not found". Then it boots from my hard disk. My PC supports USB booting and I have done it before, even from that same USB. I don't really know what am I doing wrong (@.@) So thank you very much for any help you could provide me! I'm looking forward to your answers

    Have you tried a different USB drive?
    Have you checked the MD5 hash?
    Have you tried another program to make your USB drive bootable?

    Probably is not finding the kernel image and the initramfs image.

    Did you formatted the usb as fat32?..If not, it should be done so....

    Luck.

    Question Can't boot from USB


    Hello Guys,

    Im new to Linux and BT, having same issue with booting to live USB.

    - Formatted USB Stick as FAT 32
    - Verified BT 5 R2 file with Hash Calc (Checked OK)
    - Used Power ISO to make RAR from download to an ISO
    - Used Unetbootin app to burn ISO to USB (Burned Successfully)
    - Restarted computer and booted into BIOS
    - Changed Boot Sequence for USB (Saved and Exit)
    - Restarted PC and did not boot to USB (Booted To HDD/Windows)
    - Tried Other USB Ports (No Difference)
    - Reformatted and repeated steps

    Any suggestions greatly appreciated...

    I do not understand: Used Power ISO to make RAR from download to an ISO?..The download comes in .ISO format..You are doing something wrong...There is only 2 download formats: ISO and VMWare..You need to download the ISO..But RAR?...

    Check the download page..You will see there is no RAR download in any of both 32 and 64 bit BT5 .

    Does your bios support a keystroke menu e.g f12 during bootup that lets you manually select a drive to boot from... I know youve selected in the bios boot order but just to be sure the bios is pointing to the right drive...

    Don't use Power ISO to make bootable USB.
    Power ISO is not reliable as unetbootin because that's new feature in Power ISO.

    download newest unetbootin and that should work.
    also do not use preserved space option in unetbootin because that didn't work with my KDE version of bt5r2 (not sure for GNOME)

    Also try GNOME version, it's more stable then KDE.
