I just upgraded from the e6600 to the q6600 and I am having problems installing the operating system. I have tried my copy of xp and it loads and then says that I am missing the ntloader file while rebooting. I have also tried my vista and it never get thru with the install sayin that certain files are missing from the cd. Any help will be much appreciated. I have checked all the connections on the hardware and they are all in so I dont know what else it could be.
