LL2 not booting if one extended partition is formatted to FAT 32

[arunp]

Dear gold_finger,

I have tried all the options as you have said in the mail earlier;

First: During installation i added it to sdb1 as logical FAT32 partition - result - After Grub boot screen the OS doesn't start

Second: Using LL live CD and G parted removed this FAT32 and made it as unallocated using Gparted - result - After Grub boot screen the OS starts fine

Third:  During installation i added it to sdb1 as logical e4xt partition - result - After Grub boot screen the OS starts fine

Fourth: I installed as given in the screen shot of my earlier post and using Gparted made it as another Primary FAT32 partition - - After Grub boot screen the OS doesn't start 

As you mentioned I want to know how to configure FAT32 partition set-up during installation

Also i want to know how to assign it as another primary FAT32 partition and mount it automatically on each start-up.

Pl guide me...
