Previously, it supported the situation that /boot area with separate boot partition: ... menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" { set root=(hd0,1) linux /bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp } ... But didn't consider the situation that /boot within root partition: ... menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" { set root=(hd0,1) linux /boot/bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp } ... We should support them both.
