Re: Problem creating iso for a USB stick
Hi,
i am the developer of xorriso and always interested

What kind of machine do you use ?
What kind of firmware does it have: PC-BIOS , UEFI, ... ?
How far does it get with booting ?
Does the USB stick make any difference when plugged in
or is it just ignored ?
How did you put the result onto USB stick ?

Did you submit it as emulated hard disk (rather than as CD-ROM) ?
BIOS treats both device classes very different. (MBR vs. El Torito.)
An USB stick would be treated by real BIOS as hard disk.

This looks ok as far as PC-BIOS booting from USB stick is
concerned. It should work on i386 and amd64 processors.
You may leave out -partition_offset 16 and check whether this
changes anything with bootability. Some machines demand it, some
hate it. Most work with both variants.
(If you want to see "Custom Install CD" as name of the filesystem
then you should use -V rather than -A.)
Have a nice day :)
