Wanted to quit last night after weeks of trying and failing. Woke up this morning and decided to give it one more go by following your instructions EXACTLY. Re-downloaded PEtoUSB, Windows 98SE boot files, GRUB4DOS and retrieved my old UBCD SP2 disk (previously I used a BartPE SP3). And it worked the first time. I finally have a 4G USB FAT32 flash drive that boots. TY TY TY.
