after your upgrade to A05 did you do step #1 and check if AHCI in on.
it's better to use a new hard drive, but if you already have window on it you will have to format your drive with disk utility to install 10.6.3
at boot try -v -f
Yes AHCI was defiinately selected.
I do already have windows installed on the machine, however this has been imaged and I'm not bothered about having to format the drive. Does this need to be done so that I can get the installation process to start? Note: I cannot even get to the accepting the license, so I don't have a chance to get to Disk Utility.
How do I enable -v -f? I use the BootCDE6410 boot CD then boot the Retail DVD.
I have tried pressing F8 while both are loading but nothing happens...
