My constant struggle is some motherboards (mine!) refuse to boot the Windows installer from the UDF-formatted image Microsoft provides as a download; IIRC I have to copy all the files to a FAT32 partition on the disk instead. (I assume their installer-creation tool, which naturally requires an already-working Windows install, plays some games with creating a disk that's both FAT and UDF, and building all the right tables for files to show up in both? Never dug into it though, this is just conjecture.)
