    unetbootin, failure to boot after creation

    I went through the USB creation process but am now unable to boot from the usb. I know my bios is caplable of booting USB's.

    host: ubuntu 12.04
    create usb: ubuntu 10.04 live, capacity is 4GB
    selected 200MB persistent

    Directory of usb

    felix@xxx:~$ ls -l /media/KINGSTON

    -rwxr-xr-x 1 felix felix 1934624 Sep 14 2011 urDrive.exe


    On attempting to boot there is a countdown timer that starts at 10, when it reaches 0 it just starts at 10 again

    The tab key produces,
    ">ubnkern initrd=/ubninit persistent"

    Thanks for any help

    Double-check that you used a valid 10.04 image.
    Try making the USB Stick again.

    The directory listing you posted seems to have neither a kernel or a compressed-system to use that kernel, both of which come from the 10.04 image.

    Re: unetbootin, failure to boot after creation

    Thanks for infomation

    This is where I got it from. A fresh the iso image was downloaded by the program in each case.
    http://unetbootin.sourceforge.net/

    To my amazement this time the result was different, there are even less files put onto the usb. This looks to me to be some sort of buffer problem, at least that's my guess. The corrent files being sent to the usb by the program ( unetbootin-linux-575 ) but then not being written to the usb before closing down. Any ideas?

    First try, selected reboot at end
    Second try, selected exit and then closed down
    Will now try exit, list usb files, umount usb, and then closing down?

    Re: unetbootin, failure to boot after creation

    You can see here it is just not putting on all the files on the USB. Next I'll try downloading an ISO image from this site and then comparing it to the one I'm already using.

    Re: unetbootin, failure to boot after creation

    I have isolsted the problem a bit but not solved.

    It makes no difference what OS or iso I try to load, the list of files copied to the drive varies each time and of course it never boots.

    I'd be very surprised if it's a unetbootin problem now. I tried a different usb drive by a different manufacturer and unetbootin for that worked fine. I bought 4 new USB drives last week, all the same manufacturer ( KINGSTON ) and none of them work. It comes with something called urDrive that seems difficult to get rid of.

    I tried "dd if=xxx.img of=/dev/sd?" and seems to copy the image but won't boot.

    I even tried "dd if=/dev/zero of=/dev/sd? bs=4096" to try and destroy whatever is on the USB but after creating the partition table again etc etc. it was still the same. I am wondering if the usb appears to be something that it is not.

    Wasted hours on this.
