If you purchased your laptop directly from someone like Dell or IBM, then it should have come with a "recovery disc" or something to that affect.  Insert the disc and it should walk you through it.  If you have any tough questions, call the manufacturer.  This will restore it to an "out-of-the-box" laptop.\n\nHOWEVER... the way you phrased your question, and the fact that you're asking it here, it sounds like it won't be that easy.  I would say:\n1. Burn anything you want to save - you will loose everything!\n2. Find a copy of Windows (make sure you have a CD-key BEFORE you start) and broadband access.\n3. Either run the CD or boot to it and begin formatting your hard drive.\n4. Create 2 patitions on your hard drive - one for windows and the other for documents, music, games...\n5. After install, check Microsoft's website for updates.  You may have to do this 3 or 4 times.\n6. Reinstall all other programs and software.\n\nThis is the "Cliff Notes" version.  Check the website below if you have any questions.

just reformat everything.  the windows o/s you have should boot automatically from your CD-ROM.  there are free utilities from majorgeeks.com to retrieve your lost data, even if you've reformatted the drive(s).  good luck, you're NOT an idiot.  everyone has had their computer woes.  how'd your Vista go?

Well, i think you formulated the question wrongly. You can always restart the computer without a CD. Once Windows has been installed in your hard drive the first time, it'll boot from it all the time. Now, if you meant "reinstall" that's another story. If some of the files have been corrupted and you are not able to start windows normally, the you would have to repair or reinstall windows depending on the problem. If you need more info i got more specific answers for you. Just write me an email!\n\nGood luck!

If you are able to use the old disk drive with the old installation of windows xp on it then it is the simple task of using the following free software to recover your product key.\n\nhttp://www.magicaljellybean.com/keyfinder.shtml\n\nBut if that is not possible to do that then a call to microsoft customer services will help you as long (as you have a real copy of windows).

Don't need to do anything hard. Insert your Windows Installation CD-Rom in the Drive, boot your system from CD-ROM, then go on installing windows, then Select " Repair Windows ", that's all you need to do,, nothings gonna change ...

I am assuming that you are saying you lost your windows operating system and CD. If so, you can buy a new version at  the store, which would cost you about eighty dollars. You could also download it if you want to off of the internet either for a fee or for a cost. Downloading it for free is illegal though.

Go to add&#92;remove programs and click to uninstall explorer. It should give you the option of repair. Select this.\nIf this doesn't work, format the drive and reinstall your windows.

You First Have To Insert The Windows XP Disk that came with your PC At Start Up. Once you do that it should say "Press Any Key To Boot From CD". At This Point You Press Any Key.After you do that you will be lead to a blue screen that starts loading a bunch of things. Once it is done loading you have to acsept the licence aggrement from microsoft (I think you press F8 but it will tell what to press). You will then be asked if you would like to repair windows. Cancel and press escape. You Will Then Be shown all the partions on You HardDrive. Delete all the partions (except the unused on). You Have Now Erased the HardDrive. If You Want to install windows again you must create another partion. If you are using only one operating System use the max space alloted. Your new partion will then be formatted. Once that is complete some new files will be written to your hard drive. Now after that is complete your computer will restart and automaticly install windows. From Here all you have to do is pedioticly enter some information (Ex. Name, Time Zone). That Is How Erase A Hard Drive. Note that this could take up to 3 hours. Good Luck.
