is there anything that needs to be done after installing 10.5.5 such as patching it to work or replacing any files once the install has completed? It says it has completed the install successfully but then when i reboot it resets the machine as it is loading up on the apple screen (seems to be at the point it would switch to the blue screen).

I removed all ATI related kexts as I don't have any ati hardware, plus the intelcpumanagment kext

an error i have noticed when exiting out of single user mode is UUID of on-disk kernel (mach_kernel) does not match running kernel

Could this be what is causing the reset? if so how would i go about fixing it?

any help gratefully appreciated as always

edit: using -x -f boot options i got to the blue screen after the apple logo with a working mouse but nothing displayed, just blue screen and mouse pointer. Reinstalling backup again
