Description
When a disk already contains an Intel partition table, you can't write the boot code in the MBR (except to play with "dd" and a 'good' MBR)
As a workaround, you must :
-clean the MBR with DiskProbe ( write zeros to replace all the MBR content, especially the last 2 bytes).
-reboot
-create the partition table, create and format the partition.
Since USB flash drives rarely have a working MBR boot code, the installation is very difficult for unexperienced users.

It's also a problem if you have multiple partitions on your disk.
Then DriveSetup need a command "FixMBR" to write the boot code.
