After looking bug #499176, I found the cause of my problem. In /boot/grub/device.map (hd0) /dev/hdb
But my hd0 is /dev/hda When I installed Debian Lenny, this disk is the slave disk, but sometimes later, I changed it as the master disk. I changed fstab, menu.lst etc but I forgot to change devices.map After changing device.map, I installed linux-image-2.6.486 package without any problem.
