I had first installed XP(C drive) ,then installed Windows 7(D drive) and i had no problem switching to any OS.After 2 days when switching to XP,desktop is displayed for 2 seconds and system started to restart:S.I have tried several times and decided to format XP keeping Windows 7 undisturbed.But now when i start Switching OS login screen is not appearing and my system directly logins to XP.Windows 7 is still present in D drive so please suggest me how to get dual OS working properly with login option........
Thankss
