"missing operating system" after copying with dd

I have a message of "missing operating system" after copying with dd.

The hard disk is 250G of sata which is installed Centos 5.4 x86 and has a boot partition - 101.9 mb and an LVM - 232 Gb.

I boot by Live CD, and put this command.

> grub

grub> find /grub/stage1

At thos stage I don;t find any guide for this.

Please let me know to boot this drive.

Thanks in advance.

I've found this guide, and solved this problem.

Boot the system from an installation boot medium.

Type linux rescue at the installation boot prompt to enter the rescue environment.

Type chroot /mnt/sysimage to mount the root partition.

Type /sbin/grub-install /dev/hda to reinstall the GRUB boot loader, where /dev/hda is the boot partition.

Review the /boot/grub/grub.conf file, as additional entries may be needed for GRUB to control additional operating systems.

Reboot the system.
