Renato,

I don't think it would take that long to make a little script that even an XP user could use to generate GPT formatted thumb-drives. 

I believe someone made the Rufus utility for just such an occasion

I made a script for linux cli, that does pretty much the same thing. Since it's CLI though, you could easily edit it to sed the GUID into the syslinux configs deposited onto the partition.

Unfortunately I can't use GPT partitions because the usb stick are created
by non-technical users and lots of them are still using xp 32 bits.

Thanks
