    Stuck on boot: Syslinux Problem

    Hello there, I'm Alecossy.
    I've been using linux distros for over 4 years now, going from Fedora to Chakra, passing through ubuntu, knoppix and another couple of minor forks.
    Just yesterday I decided to remove my chakra copy to try out Ubuntu Studio 12.04 on an Acer Aspire 5742ZG laptop.
    I went straight to making the flash USB just to find that it gets systematically stuck on SYSLINUX.
    The exact message says:
    "Syslinux 4.03 2010-10-22 EDD Copyright (C) 1994-2010 H. Peter Anvin et al"
    Used to this kind of problems from other distros i tried to browse your forum looking for a solution.
    Of the few I tried none worked.
    I'm sure my computer supports USB boots because all other distros have been installed using this very USB Drive i'm using now (Including a version of Android x86) and I made the flash drive both using LiLi and Unetbootin.
    I'm now wondering, what might the problem be?

    Re: Stuck on boot: Syslinux Problem

    There are usually three possibilites:

    1) The syslinux bootloader was corrupted and needs to be reinstalled.
    2) syslinux.cfg is pointing to the wrong kernel
    3) syslinux.cfg is pointing to the wrong initrd (root system)

    Take a look at the .cfg file and try to eliminate some possibilities.

    If you don't know how to read it, post it here.

    Re: Stuck on boot: Syslinux Problem

    Here's the content of my syslinux.cfg:
    Note that I never used syslinux before so I'm completly new to the whole thing.
    Code:
    default menu.c32
    prompt 0
    menu title UNetbootin
    timeout 100
    
    label unetbootindefault
    menu label Default
    kernel /ubnkern
    append initrd=/ubninit file=/cdrom/preseed/ubuntustudio.seed boot=casper quiet splash --
    
    label ubnentry0
    menu label ^Help
    kernel /ubnkern
    append initrd=/ubninit 
    
    label ubnentry1
    menu label ^Try Ubuntu Studio without installing
    kernel /casper/vmlinuz
    append initrd=/casper/initrd.lz file=/cdrom/preseed/ubuntustudio.seed boot=casper  quiet splash --
    
    label ubnentry2
    menu label ^Install Ubuntu Studio
    kernel /casper/vmlinuz
    append initrd=/casper/initrd.lz file=/cdrom/preseed/ubuntustudio.seed boot=casper only-ubiquity  quiet splash --
    
    label ubnentry3
    menu label ^Check disc for defects
    kernel /casper/vmlinuz
    append initrd=/casper/initrd.lz boot=casper integrity-check  quiet splash --
    
    label ubnentry4
    menu label Test ^memory
    kernel /install/mt86plus
    append initrd=/ubninit 
    
    label ubnentry5
    menu label ^Boot from first hard disk
    kernel /ubnkern
    append initrd=/ubninit

    Re: Stuck on boot: Syslinux Problem

    Looks like the install is set up for a LiveCD instead of a LiveUSB environment. Perhaps you simply copied it over? If so, that won't work; it needs to be installed properly - the CD and USB environments are a bit different.

    How, exactly, did you create the bootable USB?
    What program did you use to create it?

    For example, take a look at this line from the syslinux.cfg:
    append initrd=/ubninit file=/cdrom/preseed/ubuntustudio.seed boot=casper quiet splash --
    See how the system is looking for a preseed file on the CDROM instead of the USB?

    Are you really trying to install Ubuntu Studio? Is the preseed file on your USB stick?
    If so, simply fix the string(s) to reflect the correct location.

    Re: Stuck on boot: Syslinux Problem

    As I said, I used Unetbootin - 575, Windows version.
    I simply downloaded ubuntustudio-12.04-dvd-amd64.iso from the ubuntu studio site and ran a checksum to be sure, then I opened Unetbootin and selected "ubuntu" and the 12.04_live_x64 version.
    I then selected the drive and hit the okay button.
    The result is what you see before us.
    Did I do something wrong?
    I also tried to use LiLi (which is a windows application called LinuxLive USB Creator) but the result was the same.

    Re: Stuck on boot: Syslinux Problem

    Perhaps you did something wrong. Or perhaps you have discovered a bug with the way unetbootin handles preseed files.

    Doesn't seem relevant to your problem right now. We know what the problem seems to be in the syslinux.cfg file.
    Do you understand how to fix it?

    Re: Stuck on boot: Syslinux Problem

    hi, first of all sorry for my english, not my native language, i have made some research with the info posted here, and made some tests, i had the same problem running any distro: i've tried ubuntu, linux mint, and wifiway, and made tests with yumi and unetbootin, and tested it on 2 laptops, the first one (sony vaio) booted the livecd on the usb stick normally with no problems (any distro, with unetbootin or yumi) the other one (lenovo g475), didnt run any of them, no matter the distro, no matter the software used.
    but if i use wifiway with unetbootin and then i run \boot\bootinst.bat
    this script primarily what it does is to run this command
    \boot\syslinux\syslinux.exe -maf -d \boot\syslinux %DISK%
    (being %DISK% the letter of our usb stick)
    the problem is solved and now i can boot wifiway on the lenovo g475
    this didnt worked on yumi because i think is a multiboot software and things arent that simple (at least for me)
    so i made some comparisons with winmerge (file comparison tool) comparing the "before command" stick and the "after command" stick, and the only thing that changed was this file:
    \boot\syslinux\ldlinux.sys
    and it was only one line of the file, saddly a text editor is not a propper tool to see that file so i didnt understand what info changed...
    so now its you turn gurus to tell me how i apply this solution to yumi, so i can have my multiboot usb stick working on any computer hehe... well, i hope i have contributed on something...

    Re: Stuck on boot: Syslinux Problem

    I am having the very same problem with my HP Mini. The only distro I could boot so far is DamnSmallLinux, which does not recognize its wireless card anyway. I have spent the last 6/7 hours trying to boot Lubuntu on it, without any luck. The drive is fine (I am typing from Lubuntu live on my Pavilion dv5 right now) as it would boot on three other terminals BUT on the HP mini. I will try to change the values of the MBR if I somehow manage to manipulate it, and let you know if it is resolutive once and for all.

    Re: Stuck on boot: Syslinux Problem

    I'm having the same issue, I'm familiar with syslinux from old days setting up pxe boot, but this is driving me a little nuts.

    I know this threads a bit old but did you guys have a Solid state drive or a Bios with EFI?

    Re: Stuck on boot: Syslinux Problem

    I had this issue today when trying to install xubuntu on my old Acer netbook using unetbootin.

    Eventually I found out that the problem was that the 1 GB USB-stick was detected as USB-FDD,
    I tried with another newer 4GB USB-stick and it was detected as USB-HDD instead.

    After switching to the 4GB USB-HDD stick, I had no problems booting and installing xubuntu with unetbootin.
