I have a DELL Optiplex 1GHz, 128 mb memory, 20 GB HD (divided into 2 FAT32 partition) running Win98 SE English. I want to install Win2k or XP Japanese version on the 2nd partition using FAT32 instead of NTFS. I know that this is possible with both OS in English. What sort of problems I may encounter?

Another question would be, What files are installed on to the C: Drive during Win2000 dual booting procedure and in what directories? Assuming the English version of Win2000 was used and NOT the Japanese version.
