I too have the same problem, i tried NUMEROUS ways of installing 10.4.9 and have no luck , nothing but a black screen with a dead cursor.
i was ONLY able to sucessfully install 10.4.8 , i downloaded the same version you have , with the 10.4.9 UPDATE included, after instaling and running OS X i applied the UPDATE, it said it sucessfully installed it, however it would not Shutdown or reboot, i had to manually turn off the virtual machine.
upon restarting it OS X would Constantly reboot. it would goto the Grey Screen with the apple then back to the boot sequence . OVER AND OVER again.
i tried all the tips and tricks i could find to remedy this to no avail.
SO!
i am here now reinstalling OS X 10.4.8 and will wait until someone can sucessfully get it updated.
ALSO .
DO NOT try to update OS X from the Mac OS X UPDATER!!!!
it will not work and you will end up with the SAME results that i have just explained....How do i know you might ask? I Tried it...how do you think i know?
So if anyone knows a remedy to this im ALL EARS
ive got a Pentium 4 Cpu 3.6Ghz
