Boot from USB-Stick – Unetbootin required, but does not work properly

[Member Xaver]

MyPC is about 10 years old.
AMD Athlon(tm) Dual Core Processor 5050e 2600 MHz
Mainboard Abit AN-M2HD (MCP68 – NVIDIA GeForce7050PV/nForce 630a Chipset))

The Phoenix BIOS does not know USB-sticks. But if I set the BIOS to boot from USB-LS120, I can boot from USB-sticks by the following trick:
– preparing the USB-stick with bootflash from PartedMagic 2013-05-01 or Puppy 4.3.1
– Then install the iso on the USB-stick with Unetbootin.

Unfortunately with antiX 17 Unetbootin does not work.
(error message: gfxboot.c32: not a COM32R)
The sticks made with the antiX methods do not work on this PC.
(They are ok – they do work on my 3 years old Asus notebook.)
Creating a non hybrid iso did not help either.

Does anybody have an idea?
Is there a way to modify the iso (i.e. with isomaster), so that I could still use Unetbootin?

That message is usually caused by the system you made the stick from not having syslinux 6.

@ dolphin_oracle
I have used unetbootin from PartedMagic 2013-05-01 to put antiX-17_x64 on the stick.
This method still works fine with Ubuntu 16.04 and with Clonezilla-live, but not with antiX.
If a missing syslinux 6 causes the problem, how can I fix it? How can Iget syslinux 6 on that stick?

That would be a question for the PartedMagic folks. Your PartedMagic iso is going on 5 years old now…

The fact that it still works for Ubuntu 16.04 (almost 2 years old, but an ubuntu LTS version, so still supported by Ubuntu), likely means that ubuntu 16.04 still uses syslinux 4, which I would guess is installed on your PartedMagic iso.

at this message (error message: gfxboot.c32: not a COM32R) on your current stick, try typing “Live” at the : prompt. (might be live or Live, I forget which).

How can Iget syslinux 6 on that stick?

Install it via synaptic package manager before making the stick with unetbootin. Check parted magic to see if installed. Might be in /usr/bin. But I don’t know for sure.

Also. This works real well on Ubuntu.

Works well in AntiX 17 and MX 17 also.

Might work in parted magic also.

prompt. (might be live or Live, I forget which).

Hit the enter key after to see if it boots.

You can probably boot the stick by pressing the key shift, when the error message appears
Then type live
Then press enter.

If booted into the stick, you can probably install sylinux to the stick
Open a terminal

sudo -i 
 apt-get update
 apt-get install syslinux
 mount | grep cdrom

The last command shows, from which device the usb-stick is booted

In the following command change the X in /dev/sdX1 , with the device you have determined

syslinux /dev/sdX1

 reboot

Thank you all for your help.
Dolphin Oracle was right. PartedMagic gave my stick an outdated version of syslinux: 3.73 of 2009-01-25.
Now I have used PartedMagic only to run bootflash (or flashboot ?) to prepare the stick for my ancient PC.
Then I have installed antix-17_x64 to the stick with unetbootin 608 from Lubuntu 16.04 to .
It installs suylinux 6.03 and the stick boots without any problems, even with the hybrid iso.
To my great joy I have now discovered, that unetbootin 608 is included in the antiX repos.
So this method will work from antiX too.
