Reinstall Darwin bootloader possible?

I need to know how to deal with missing Darwin bootloader.


The situation is like follows:


- perfectly working 10.5.6 on Dell Optiplex GX620

- create compressed image with SuperDuper! to a USB key

- change the hard drive to a brand new one

- boot off installation DVD ie iDeneb v1.4

- restore the image from the USB key to the internal drive with Disk Utility


Resulting disk has all the data, but of course does not boot


Any idea how to fix it?

i would also like to know. I some how messed up my loader because it keeps restarting on me at boot, BUT it will boot fine if i have my Leopard DVD in the CD drive. It uses the bootloader on the CD to boot.



can anyone help us please :)

Thanks, in fact all is on the installation DVD in /usr/standalone/i386/README


One needs to run the fdisk / dd from /usr/standalone/i386 directory





Normal Install (non-RAID):



Suppose that your installation is on /dev/disk0s2


- Install boot0 to the MBR:

fdisk -f boot0 -u -y /dev/rdisk0


- Install boot1h to the partition's bootsector:

dd if=boot1h of=/dev/rdisk0s2


- Install boot to the partition's root directory:

cp boot /


Works like a dream
