There is no public specification of the EXFAT filesytem, There are some
attempts to write a linux driver:

Also Tuxera wrote aa EXFAT driver for linux, based on Microsoft
documentation, but source code is not available atm (if ever):

Why don't you use ext2/3/4 instead of FAT32? Because you want to boot
linux, it can't be a problem to create/use ext2/3/4 partitions.

Never use a ISO editor to edit bootable iso's.
Always remaster this iso with mkisofs and the -boot-info-table switch if
the iso uses ISOLINUX. The -boot-info-table switch patches some bytes in
the bootsector of the CD, which are originally the first 2048 bytes of
isolinux.bin. This patched bytes tell the boot sector where the rest of
isolinux.bin is located. If your ISO editor moves the isolinux.bin file,
the location in the boot sector still points to the same location as
before, but this location doesn't contain the isolinux.bin file anymore.
