To just copy files and directories, you can use any "burner". I use
"k3b" on my KDE desktop. I used to use command line "growisofs",
but I don't burn CD/DVD much, so GUI frontend is easier.<br>
<br>
Now, to make it bootable, that's different. <br>
<ol>
<li>Since your USB stick is already bootable, you can make
duplicate USB stick and copy the image to file on your computer
as backup. That way, you can make another USB stick if needed.
"dd" is what you use. </li>
<li>If your USB stick is already "isohybrid" format, then just
burn it to CD/DVD as image. Depending on your burner program,
you may read directly from USB stick, or make image of USB stick
first and use that.</li>
<li>If your USB stick is just harddisk format, then you may be
able to convert and burn at the same time. Depending on your
burner.</li>
</ol>
<p>I recommend option #1. It came as USB stick, so stick with that.<br>

recently purchased the latest version of Eurosoft's PC Check. The
software came on two 8 GB USB thumb drives. I would like to know
how to back the contents of the thumb drives up, preferably to a
bootable CDROM, which I can not accidently overwrite, as PC Check
contains options to destructively erase hard drives.
<br>

The output of df -hT shows this:
<br>
<br>
Filesystem Type Size Used Avail Use% Mounted on
<br>
/dev/sdh1 vfat 6.5G 63M 6.5G 1%
/media/john/EUROSOFT
<br>
<br>
As you can see, the thumb drive is mostly blank and the files will
easily fit on a CDR. PC Check boots to EURODOS, and runs PC Check
from there.
<br>
<br>
I know I can use mkisofs to create an iso file containing all the
files from the mountpoint /media/john/EUROSOFT, and then write
that iso file to a CDR or DVD-R. How can I make said CDR or DVD-R
bootable? I did read the man page for mkisofs, but find all the
options confusing.
