I have installed Windows XP SP3 and the latest Ubuntu 10.04 on a 320 GB HD as a dual boot system. I have made a 125 GB partition for windows and left the rest for linux. When I boot the OSes, linux works fine, but windows takes a very very long time to boot, unlike normal windows single boot PCs. Could someone please tell me how to shorten the loading time of windows xp ? The processor is Pentium IV 2.66 GHz.
