Are you in fact using a BIOS (which would expect a MS-DOS partition table), or are you using newer firmware (which would handle the MS-DOS partition table or the newer G?? Partition Table [GPT]). Some older BIOSes don't handle partition tables on USB devices at all. Either way, it will be expecting one or more variants of FAT. Newer firmware can work with NTFS. I'd use FAT appropriate to the size of the partition. If the firmware is expecting EFI, you'll need a separate FAT partition for that. You also don't tell us the file system on the USB device. As for UDF, I assume you mean Universal Disk Format. https://en.wikipedia.org/wiki/Universal_Disk_Format Are you trying to boot a CD or DVD image on a USB device? That is an entirely different can of worms. > > How can I convert filesystems through DD? Short answer, dd is probably overkill for this. Probably. However, what you have told us so far is so vague and confusing that you should first make clear what you want to do; than we can give you more precise help. > > I want to save a copy of the file in MSDOS or GPT. MS-DOS is an operating system. It used the File Allocation Table (FAT) file system, of which there are many variants. GPT is a partition table layout. You don't save files in either one. You save files in file systems. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
