Hi, i am the developer of xorriso and always interested in learning about problems.

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 ? > I've checked the resulting iso with vmware fusion on my mac and it works, 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. > xorriso -as mkisofs -D -r -J -joliet-long -L -A "Custom Install CD" > -b isolinux/isolinux.bin -c isolinux/boot.cat -iso-level 3 -no-emul-boot > -partition_offset 16 -boot-load-size 4 -boot-info-table -o ../test.iso > -isohybrid-mbr /usr/lib/syslinux/isohdpfx.bin ../cd 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.)
