+===== Fix boot after reinstall Mac OS X  =====
+.Of course,first should install rEFIt,and sync the MBR partition list.
+.Fix the grub command,it is really strange,after the new install of Mac OS X,the sda5 has been changed to sda4,so need update all related partition index by -1.
+<code>
+splashimage=(hd0,3)/boot/grub/splash.xpm.gz
+title Gentoo Linux root (hd0,3) root=/dev/sda4 /boot/kernel-3.3.8
+root (hd0,3)
+kernel /boot/kernel-3.3.8 root=/dev/sda4
+title Gentoo Linux root (hd0,4) root=/dev/sda5 /boot/kernel-3.3.8
+root (hd0,4)
+kernel /boot/kernel-3.3.8 root=/dev/sda5
+</code>
+And the fstab also need update:
+<code>
+# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
+/dev/sda4              /           ext4            noatime         0 0
+#/dev/sda4 /boot		ext2		noauto,noatime	1 2
+/dev/sda3		/home		ext4		noatime		0 1
+#/dev/SWAP		none		swap		sw		0 0
+/dev/cdrom		/mnt/cdrom	auto		noauto,ro	0 0
+/dev/fd0		/mnt/floppy	auto		noauto		0 0
