i was installing the update and following the guide on ihackintosh. i went to go open osx86tools and it wouldnt open for some reason it would bounce once and then not do anything so i couldnt do any of the things that it told me to do. so i restarted (bad idea) and now when i start the os i can get to the bootloader fine but it will hang at the apple logo screen and there is no spinny wheel.i have tried safe mode single user and verbose mode but all that comes up is a black screen after the bootloader finishes loading its files. so is there any way i can make this thing run again or am i screwed.

Thanks.

went from 10.5.6 to 10.5.8
