If you can use Target disk mode to another mac
use that mac to run a new download of Leopard Mac OSX 10.5.8 Combo update
if it allows you to instal to your G5

Otherwise it is probably an archive and instal from Leopard disk
followed by a new download of Leopard Mac OSX 10.5.8 Combo update ( PPC version ? )

My SP G5 1.8 will not boot. Sits at the grey screen with the apple and the spinning cog.
Sequence leading up to this as follows
Downloaded 1.5.8 and proceeded with install
Instal went right to the end then came up with "Install failed source file damaged"
would not then reboot
since then I have run Disk Warrior ran to completion with minor errors only noted
still no boot
ran disk utility from leopard DVD. Completed repairs satisfactorily, it said
then ran repair permissions, many changes but ok
still will not boot
zapped pram
still will not boot though a folder icon now flashes up briefly before the apple
and the cog goes on and on

Help urgently needed
