Comment 12 for bug 769669

I will file a bug report for FAT32 vs FAt16. But I do not use Ubuntu directly and modified this bug report only becuase few users reported problems in dual-bot scenario when using FAT16 EFISYS which were solved if FAT32 EFISYS was used.

BTW NTFS is not supposed to be the FS for EFISYS partition. As per my understanding of the Spec, EFISYS part should be FAT32 for non-removable media, and FAT32 or FAT16 for removable media (with FAT12 being used for floppy discs/images). I think it might me am case of misdetection of the FS.

Also where is the 250 MB (or is it MiB) minimum size for FAT32. I have used FAT32 in 100-200 MiB partitions (both EFISYS and normal data ones) and have not faced any problems (no warnings/errors reported by fsck or windows chkdsk utils regarding minimum size limit).

While the spec does not specify a minimum size for EFISYS partition, it is generally accepted by many OS vendors to be at least 100 MiB size (200 MiB recomended).
