Why don't you just use the terminal to execute your task.Type the following code and you will be done
sudo dd if="the path of the iso file" of="the path where you want to boot for you it must be /dev/sdb" bs=2M
but first you need to format the usb stick try GParted for executing this task of formatting and format it to fat32!!
I know how to write an iso to my stick. Do it all the time so I can try live linux systems.
What I want to do is have a bootstick to use to boot my hardrive in case I bugger up lilo. I make these bootsticks regularly (lately) but they just do not work when I try them
OK, got home from town and used the same stick for Slackware Live. I booted just fine on two computers.
Just used pkgtool to make a bootstick with the same stick.
Code:
bash-4.3# fdisk -l /dev/sdb

Partition table entries are not in disk order.
bash-4.3#
This looks good! It looks just like mine on my 8GB usb stick.
There really is no "master boot record" as the stick is formatted to only contain a single msdos partition with a volume boot record.
/dev sdb1 is bootable but I sure as heck didn't make it so with fdisk so writing the iso did it.
Interesting
When you write an iso over, it contains the full filesystem, including any bootable flags. So that is why it is marked as bootable without you needing to do anything separate. If you format your own stick, you'd still need to mark it as bootable using fdisk.
For my computer, I power it up, and then press F12 to get a boot menu.
(For other computers it might be F10 or some other key...)
There I select the device that I wish to boot, given several choices.
Hard disk, USB stick, DVD drive, etc.
If I don't do this then it simply boots up to the hard disk.
Can you access the boot menu of your bios?
Good info. I just hit the power button and it boots up to lilo and then I have to hit enter. My computer has usb as the first choice to boot and the hd as the last choice. At no other time or instance is that a problem. I use live usb sticks all the time and they boot right up on the stick
OK. Just took a look and only have two choices there. Have to press F9 and the choices are internal CD/DVD or Notebook Hardrive

Reason: Add info about boot menu

I suspect the stick is good since you see the syslinux boot record and the normal files on the stick.
My system boot menu sees both a USB stick and an EFI usb stick. The elilo code on the stick makes the EFI version work.
For now lets try something else.
One user, Sargent67, found a work around in this thread:
Quote:
Here is what did work: Boot your machine and enter the BIOS config. Turn off boot security and enable legacy support. Go into your boot order and disable all but legacy devices. Reboot the machine with the thumb drive in.
There was an update today, including a new usbboot.img ...
I am not sure how 80.make-bootdisk works, nor where it gets an image.
And this is a WAG but ... Maybe updating and then making a new USB Boot Image will help ???

Some Machines won't allow you to select the USB if it's not bootable.
Some Hp's are among that category ...
I made a boot disk via pkgtools 80.make-bootdisk to a USB on /dev/sde ( yours is /dev/sdb ).
When I looked at the partition tables on my new /dev/sde, they're not marked bootable ( the same as your /dev/sdb )
The session below my sig followed my pkgtools make-bootdisk session.
In a nutshell, I went into fdisk to mark the USB Drive bootable via the 'a' command.
Fdisk was confused about the bootable flag on /dev/sde1 ???
When I typed a on the 'unbootable' /dev/sde1 fdisk said it marked the partition unbootable !
So I pressed 'a' and 1 again and saved & exited the fdisk session via the w flag ...
And now /dev/sde1 is marked bootable !
Maybe you could try 'one more thing' ...
Make a new USB boot disk via pkgtool and then leave your USB Drive plugged in and continue ...
These are the commands I typed to mark my USB Drive as bootable ( The #-strings are comments ; DO NOT TYPE the comments ):
Code:
fdisk /dev/sdX # your USB was /dev/sdb
p # print partition table ; note sdX1 is not marked bootable
a # toggle bootable flag ...
1 # ... on partition 1 ; note fdisk says bootable flag is disabled now !!! ???
a # toggle bootable flag again ...
1 # ... on partition 1 ; note fdisk says bootable flag is enabled now
p # print partition table ; note sdX1 IS marked bootable now
w # save and exit
fdisk -l /dev/sdX # note that partition 1 has a bootable flag now ...
Try booting the USB now ?
-- kjh
p.s. having said all that ... the file system on the USB Drive is not really in a partition, it is on /dev/sdX.
This fdisk business is an attempt to trick your BIOS into including the USB Drive in the bootable medium list.
p.p.s. This was my fdisk session ...
