I tried both the options.
a) I changed on the SD Card (I boot from an SD Card) - no effect
b) I changed the install.sh script in initrd - no effect

Any of the above did not work.


One more information: I have changed the first partition (on which GRUB
resides) from ext3 to FAT32 partition. I made this change in the install.sh
script. Would it have any impact? Would GRUB behave differently when run
from FAT32 partition?
