I got a problem with my lap top HP it uses Home premium Vista 64bit. I reformatted the entire system. I don't have home premium vista cd to recover it, so i used vista ultimate 64 bit, when it starts to read the CD it stops and it cant go any further so it stops installing. However so i tried to down grade it to windows XP Pro, it does totally different it says there is no hard drive detected. But now i tired to install Linux Mint, and it works ta da but i don't want to use Linux. What the hells the problem it cant be my hard drive, because it gets detected even though my XP says its not there the cd works on the other computers that i have, so it cant be CD. I played with BIOS i set to defaults, i put the proper boot still same old thing. HELP ME PLEASE!!!!
