Oops. I should have proposed ls -ld so that we see the directory's info rather than the one of its content. Please retry.

Please run this xorriso command on the modified ISO (i assume the USB stick is /dev/sdc) and send the output to me directly: xorriso \ -indev /dev/sdc \ -pvd_info \ -report_el_torito plain \ -report_system_area plain With the original ISO it reports: Volume id : 'siduction' ...

A "protective" MBR partition of type 0xee and a GUID partition table (aka GPT). And you got it to boot by setting the boot flag to partition 1 ? Or was it bit 1 of the GPT partition ? The GPT flags mean: bit0= "System Partition" Do not alter. bit2= Legacy BIOS bootable (MBR partition type 0x80) bit60= read-only Now i wonder what changed by your manipulation, MBR partition property "Status" or GPT property "partition flags". Have a nice day :) Thomas
