I replaced the hard drive in my laptop (HP HDX 16), going from a WD scorpio blue to the scorpio black. I reinstalled windows, which took about 5 hours. The hard drive activity light was on constantly and every step took forever. Now that windows is installed it is taking forever to boot, and again the hdd activity light is on constantly. Any ideas? I tried running linux on it and it works perfectly, what's up with windows?
