I guess you are using Windows XP on your system. If that is the case then simplest way of getting the problem resolved is using System Restore. Start -> Programs -> Accessories -> System Tools -> System Restore and at this point select a date and time ( one of those highlighted) before you opened and installed the application ( make sure that the one selected is  system check point , you will see that in the small windows on the right side of the screen) and then proceed to restore the system to the earlier date .. this will work on windowsx 2000 also .. \nAll the Best

There may have been catastrophic damage to your system. I suggest backing up your data and reinstalling Windows off the OS disk that came with your computer.

Step 1:  Get rid of windows ME.  It's crappy and nobody uses it anymore, because nobody liked it in the first place.  You can run either windows 98 or windows 2000 on that machine.  \n\nStep 2:  Follow step 1, your problem will be solved.

Go to Start and click on help and support\nSystem information\nView the status of hardware and software\n\nThis should give you a list of all the applications and devices on your machine\n\nIf there are any conflicts, you will see the software causing the problem.\n\nLook under obsolete application and device drivers

It seems that your MBR (Master Boot Record) is wiped out and thats why it doesn't recognise the presence of the Operating System.\n\nTry repairing Windows from the CD\n\nIf this doesn't work, then try going through the Setup process normally, choose to leave partition intact [DO NOT FORMAT], and after the blue screen is over, remove the Installation Media and press F8 before Windows starts loading, choose "Safe Mode Command Prompt Only", then type in "Win"\n\n\nPS: I tried something similar, but in a different scenario, so, if you are a risk taker, try it, otheriwse, might have to install a fresh copy of Windows...\n\n\nGood Luck...

You probably have to put your PC into system recovery (non-destuctive) mode.And your windows application will be restored.

The correct answer is to reinstall W2000.\n\nBoot from the W2000 CD (you do have one, don't you) choose install W2000. After a few screens, you will get a message that a previous version was found and do you want to repair it. Answer YES and the system will be rebuilt without loss of data.\n\nBEFORE YOU START, ensure you have the CD Key 26 digit code.

check your bios to see if the drive is being properly recognized. You may need to properly partition the hard drive, but that would be unusual if you are installing windows from this century.

Install your upgrade packs, and if it still doesn't work, you might have to upgrade to win2000.  I can't think of any really stiff requirements for it.\n\nThe computer guy

You might want to think about reformatting your hard drive and doing a fresh install of the operating system. This is usually a last resort after all other troubleshooting is done. If the install does not work then you might be looking at a hardware problem.
