text: needs help on reinstalling windowsxp pro? i have been using my pc which installed windowsxp pro for a year. yesterday  it couldn't start normally again. when i try to turn on my pc it prompts me  to choose start with 'safe mode', 'start normally' or 'start with command  prompt' etc. no matter which one i choose, the system restarts again to the  same page and prompts me to choose again.  can anybody let me know how to make it work again, or if i have to reinstall  windowsxp, how can i install it without needing to format my hard drive? if you are looking for installing windows xp without formatting, then i am not your piece of cake. but i can solve your probs. when the options menu you said occurs again, choose safe mode and boot. windows xp will boot whatsoever. then windows xp will automatically rechange you settings to the last working configuration. if this does not work, go to start -> acessories -> system tools ->system restore. the comp will restore your spec as according to the date u want. if you insist on lazy methods and don't want complication, use the option 'boot with last known good configuration'(though this menu comes when the os gets frustrated{after several reboots}). if not all this best reinstall windows xp. simple procedure, just insert the disk and it will guide you through.
