OK right now i have a HP Dv2000 (dv2125nr to be specific) and it is giving me some problems. When it starts up it will not read the hard drive and flashes “Operating System Not Found” I try to install windows and the setup cannot find a hard drive. However its not entirely not there because when i run a live Linux cd (ubuntu) it can find my hard and let me look at everything that is there. I rewrote the MBR to try to fix it and that doesn’t help. How can i fix the fact that my laptop bios will not read my hard drive unless there is a live linux cd running on it?
