The <br>
software came on two 8 GB USB thumb drives. I would like to know how to <br>
back the contents of the thumb drives up, preferably to a bootable <br>
CDROM, which I can not accidently overwrite, as PC Check contains <br>
options to destructively erase hard drives.<br>
<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 <br>
easily fit on a CDR. PC Check boots to EURODOS, and runs PC Check from <br>
there.<br>
<br>
I know I can use mkisofs to create an iso file containing all the files <br>
from the mountpoint /media/john/EUROSOFT, and then write that iso file <br>
to a CDR or DVD-R. How can I make said CDR or DVD-R bootable? I did <br>
read the man page for mkisofs, but find all the options confusing.<br>
