I have not seen this problem before.  You might try again and make a /boot
partition (about 25MB or so).

I can't create boot partition because I have already had two FAT32 partitions, 
and I need one /, one swap. Is there anyway to create one more /boot, to make 
it 5 partitions in one harddisk?

I found it is because LILO can't handle cylinder number > 1023 if use MBR. Is 
there a way to fix it? I hate using floppy to boot into Linux - so slow!

I have had the same problem when I was trying to install Redhat Linux 7.0 on my 
system with 2 partitions. I tried changing the amount of space on the second 
partition so that I could some left over in unformatted space, but, like you, I 
got an error telling me that I needed to have an extra primary partition left 
over for the /boot directory or the <swap> directory (it actually happens to 
what ever Linux partition that is made last under disk druid). I then gave up 
and found out that I had to have one Win32 partition and the rest Linux 
partitions and arranged it that way. Needless to say. the installation went 
without any problems and I was able to boot into linux. Later, when I decided 
to boot into Windows, I found that the partition that I had setup for linux had 
somehow messed with my Windows partition and put the whole hard drive in MS-DOS 
mode and practically killed Windows. I had to delete the Linux partitions and 
reassign the now free space back into Win32. Then I tried to do a partitionless 
install, using the update disk for anaconda, I found that my system could not 
process the loop created by linux and it CRASHED!! But I was able to get the 
error code:
