“Boot Error” on live-usb flash drive with 15.10


Ubuntu live usb boot error

I just created a bootable Ubuntu usb drive using Unetbootin, and found that it does not boot properly. On bootup it shows the following error.

SYSLINUX 6.03 EDD 20150813 Copyright (C) 1994-2012 H. Peter Anvin et al Boot Error

The problem is with the way, the iso is written to the usb drive by tools like Unetbootin. To fix this, the iso has to be written directly to the drive. There are 2 ways to do this -

Method 1. Write the iso to usb using dd command

Use the lsblk command to find the usb device name.

$ lsblk -d NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 111.8G 0 disk sdb 8:16 0 465.8G 0 disk sdc 8:32 1 15.1G 0 disk sr0 11:0 1 1024M 0 rom

Its sdc here, so the device path would be /dev/sdc

Now run the dd command to write the iso file to the usb drive.

$ sudo dd if=ubuntu-15.10-desktop-amd64.iso of=/dev/sdc bs=1M

Now the usb should boot fine.

Method 2 - Use Gnome Disks

Many Linux enthusiasts want to try Ubuntu to learn about it, but don’t know how to install it safely on their Windows machine. Wait! Before installing Ubuntu on your machine you can taste its flavor by installing on a USB Pendrive. But main problems that many users facing are boot error and their motherboard doesn’t have USB boot support. But, don’t worry! Here is how to overcome these two situations.
To make a bootable live Ubuntu USB drive following things is required

ISO image of Ubuntu operating system (Download it. Tested with Ubuntu 10.10 Netbook edition) Unetbootin (download it from here) USB flash drive (tested with Sandisk 4Gb pendrive )

Now How to create bootable Ubuntu Live USB drive

Insert USB drive into your PC and format it in FAT 32. Run UneBootin (no installation required). Select distribution (here is Ubuntu) and select version (10.10_live). These two things should be exact; otherwise you’ll get boot error. Now select ISO and browse for the Ubuntu...

I am trying to download Windows 10 and install it at a later time when I am ready.

I am upgrading from Windows 8.1 (x64) to installing Windows 10 using the Media Creation Tool, I am getting the error:

"We can't find a USB flash drive."

1. I tried refreshing the Drive List as suggested. That did not work.

2. I tried a different USB physical location located on my ASUS cpu tower. That did not work.

3. I tried deleting all but the necessary file (Media Creation Tool) on the USB Drive (located in G:) and even tried refreshing the Drive List again after I did this. That did not work.

4. I tried right-clicking on the G: drive under This PC (located in C:) and clicking on Format... and reformatted the USB drive by wiping it clean. That did not work.

5. The requirements of storage is 4GB. My USB Stick is 16GB. So that is not the problem.

6. I know that the USB stick works because I saved and later copied a Notepad file and uploaded...

The general procedure to install Ubuntu (or Ubuntu flavour, Kubuntu, Lubuntu, Xubuntu, ...) from a USB flash drive is:

Acquire the correct Ubuntu installation files ('the ISO') Put Ubuntu onto your USB flash drive Configure your computer to boot from USB flash drive and boot from it

Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ...) before installing it

Install Ubuntu to your internal drive (hard disk drive or solid state drive).

Ubuntu can be installed from a USB flash drive. This may be necessary for netbooks and other computers without CD drives and is handy for others because a USB flash drive is so convenient. Also, you can configure Ubuntu on the USB flash drive to save changes you make, unlike a read-only CD-ROM drive.

Booting from a USB flash drive created with usb-creator alias Startup Disk Creator and mkusb will behave just as if you had booted from the install CD. It will show the language selection and then the install menu, from which you can install...

I have been stuck on this for days now. I want to install ubuntu and uninstall windows 8.1 on my acer

1.Downloaded ubuntu 14.04/15.04 went smoothly

Download linux live usb creator and another live usb creator

Formatted usb fat32 and created live usb on sandisk 32gb and pny 16gb

disabled fast startup

in uefi mode

plugged in usb then restarted and clicked f-12, but windows is the only bootable option. I tried this for both ubuntu versions on both flashdrives with both live usb creators and also have tried doing it with secure boot off.

My first time trying it the sandisk 32gb with ubuntu 14.04 appeared in the boot menu but gave me a premature file error.

8.since then i have had no look getting my live usb to appear on the boot menu when plugged into my computer the usb is displayed as "install ubuntu" with the ubuntu logo.

Could it be a problem with my...

Hello Tenforums.com

No matter what I do, my Lenovo Flex 2-14 doesn't seem to recognise my USB as an UEFI Windows bootable flash device, despite following this guide https://www.tenforums.com/tutorials/2...dows-10-a.html (Option 2), step by step.

I am using a Verbatim 16GB USD v3.0 with Windows 10.10586 x64 on it, and I tried from all three USB-slots on the laptop.

BIOS configuration is as following:

Wireless LAN: Enabled
SATA Controller working mode: AHCI
Hotkey Switch: Hotkey Mode
Power Beep: Disabled

I cannot make a USB boot drive with the Ubuntu Startup Disk Creator in Lubuntu Wily beta 2.

The SDC no longer complains about udisks. It finishes and seems successful, but the created pendrive does not work: There is an 'early error' when booting, a black screen with white letters at the top:

"SYSLINUX 6.03 EDD 20150813 Copyright (c) 1994-2014 H. Peter Anvin et al

Boot Error"

I tested with 'the easiest case', in a live session of Wily: I tried to create a pendrive with Wily of the same architecture (i386 --> i386).

Another user reported a case with amd64 (in 15.04), so the bug seems to affect both architectures.

Flash media offer speed and flexibility

That ultra-light netbook PC was great until some malicious code or innocent mistake hosed its operating system. A rescue CD could get it back up and running, but the tiny PC lacks an optical disk drive. Now what to do?

The one media connector found in all modern PCs is the USB port. If you don’t have an external CD/DVD drive sitting around (and most PC users don’t), one of the cheap and ubiquitous flash drives may be the best way to provide access to otherwise-inaccessible files and possibly fix the broken OS.

Even if you have an optical drive, booting off flash has considerable advantages over laser light. Flash media is faster and far more easily erased and rewritten, making it exceptionally flexible.

There’s just one catch: it’s more difficult to set up a Windows rescue system on flash drives than it is on optical media. You can’t simply double-click an .iso file and burn it onto the flash...

Many computers do not have the external CD/DVD drive and thus you need the bootable USB drive to install Windows. Creating a bootable USB is fairly easy and all thanks to some really good freeware programs available for this purpose. But, what if the computer wouldn't boot from the USB drive? If you have run into such a problem, here are some solutions for you.

Part 1: Check If Your PC Supports USB Booting

Your computer will boot from the USB bootable drive only if it supports this type of boot. Not all the computers support USB boot. While most modern computers today support USB booting, there are some that do not. In order to find whether your computer is USB bootable or not, you will need to check the BIOS setup. The steps may vary across computer models but remain more or less the same for all PCs:

Step 1. Restart the computer or if it is shut down, power it on.

Step 2. When the PC starts to run, on the first screen it will display the key you need...

After using Tuxboot 20101224 to create a USB flash drive with GParted
Live stable (0.7.1-1), the USB flash drive failed to boot. Following
are the steps I used and comments:


1) I started with a working USB flash drive with System Rescue CD
version 1.6.3

2) Next I downloaded GParted Live stable 0.7.1-1 .iso file

3) Then I started Tuxboot and chose the option to use the .iso file.

4) Then I clicked on the button to start the process.

5) When prompted if I wanted to overwrite some already existing files,
I chose "Yes to All".

6) When the process was complete, I rebooted the computer with the
USB flash drive still inserted.

7) The computer booted to a screen that listed details about Syslinux
including the version. Unfortunately nothing happened after this
point, even if I pressed keys such as "Enter".

My guess is that this problem might be related to the GParted Live

I tried to boot my target with an sdi image but I have an error message :

Windows could not start due to an error While booting from RAMDISK.

My Bios don't emulate the USB hard disk (when I boot with DOS, I don't see
the USB hard disk) but detect if an USB flash disk is connected and boot
with it.

I prepared my USB flash disk with an other platform.

I generated my image included Windows RAM disk and terminated FBA phase on
my target hard disk.

I verify the sequence boot.

NTLDR launched correctly

NTDETECT launched correctly

Fist Try:

I copy the target hard disk on USB flash disk.

I can't boot with USB flash disk.

Second Try:

I generate a sdi file with the target image, and modify the boot.ini on the
USB flash disk.

Fixing problems with installing Ubuntu from a USB flash drive

David W. Pierce / Scripps Institution of Oceanography / 28 May 2013

Do you have problems installing Ubuntu from a USB flash drive? For years I did too. This perl script is designed to fix the problem.

Description of the problem:

Installing from the USB flash drive seems to work, but soon into the process you get this error message:

There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM.

Failed to copy file from CD-ROM. Retry?

Retrying does not fix the problem. Using a new, or different, USB flash drive does not fix the problem. As far as you can tell,


fixes the problem. Screaming and cursing ensue.

How to fix the problem:

Make your USB flash drive as per normal (i.e., the one that doesn't work). I use Linux Live USB creator If you are making...
