GRUB重装遇到的异常

今天在台1U的服务器上了安装RHEL6.2,其中1，2号SATA盘安装了WINDOWS2008R2，3，4号盘是SSD，再外接一个DAS型存。机器里面有二个LSI阵列卡。
安装时，我选择了优先WINDOWS。安装完成后重启，直接报DISK ERROR.没法只好去修复，当时报/dev/sda does not have any corresponding BIOS drive。

RHEL6.2

boot cdrom to linx recume，choose 'continue',

#chroot /mnt/sysimage

#grub-install /dev/sdc --when you are intslled OS disk

tip err

/dev/sda does not have any corresponding BIOS drive ---???
